Covid precautions and regulations
We are committed to providing a safe environment for all participants of the conference. The event will be held in accordance with the local public health regulations valid at the time, which can be found here:
In summary, as of August 2022, almost all Covid restrictions have been lifted. Masking however, at least with a medical mask, is still required in public transportation. Regarding the LMU premises the recommendation states: The wearing of masks is no longer compulsory. People are recommended to continue wearing surgical or FFP2 (N95) masks in cases where close contact with other individuals (without a minimum distance of 1.5 meters) is unavoidable (e.g. in facetoface meetings, teamwork situations and longer periods of inroom presence).
In addition to that, and due to the rising case numbers and the absence of the summer slump in this year, we would kindly ask all participants to voluntarily do a selftest prior to their travel/arrival. For example, the following test station is in walking distance of the venue: Apotheke Maxvorstadt. Finally, in case you think you experience Covid symptoms, please stay at your accomondation and do not independently see a test station but ask the hotel to call a doctor who will then arrange a testing under safe conditions.

Titles and Abstracts
Sheldon Goldstein: Bohmian Mechanics, Detlef, and OOEOW
Bohmian mechanics is the interpretation of quantum mechanics, or, better, version of quantum mechanics, that is most naturally suggested by the experimental facts that led to the rise of quantum mechanics in the first place. It is also the version of quantum mechanics that most naturally and most crisply accounts for the new experimental facts, such as quantum probabilities and quantum nonlocality, predicted by quantum mechanics.
« ProgramStefan Teufel: Equilibration of Superposition Weights for Macroscopic Subspaces
To study the longtime behaviour of the unitary evolution of an isolated macroscopic quantum system, we assume (following von Neumann) that different macro states correspond to mutually orthogonal subspaces \(\mathcal{H}_\nu\) (macro spaces) of the Hilbert space. Let \(P_\nu\) denote the projection to \(\mathcal{H}_\nu\). A pure state \(\psi_t\) will generally be a superposition of contributions \(P_\nu\psi_t\) from different \(\mathcal{H}_\nu\)'s. We ask how the superposition weights, i.e., the sizes \(\P_\nu \psi_t\^2\) of these contributions, evolve for a typical initial state \(\psi_0\) starting in some (possibly nonequilibrium) initial macrostate \(\mathcal{H}_\mu\). We show that for large dimension \(d_\mu := \mathrm{dim}(\mathcal{H}_\mu)\) the weights \(\P_\nu \psi_t\^2\) evolve nearly deterministically for most \(\psi_0\in\mathcal{H}_\mu\) (w.r.t. Haar measure) and approach certain timeindependent values \(M_{\mu\nu}\) for large \(t\). Lower bounds on the values \(M_{\mu\nu}\) can be obtained for certain random band matrices. This is joint work with Roderich Tumulka and Cornelia Vogel.

« ProgramFay Dowker: Recovering General Relativity from a Planck scale discrete theory of quantum gravity
I will present an argument that if a theory of quantum gravity is physically discrete at the Planck scale and the theory recovers General Relativity as an approximation, then, at the current stage of our knowledge, causal sets must arise within the theory, even if they are not its basis. We show in particular that an apparent alternative to causal sets, viz. a certain sort of discrete Lorentzian simplicial complex, cannot recover General Relativistic spacetimes in the appropriately unique way. For it cannot discriminate between Minkowski spacetime and a spacetime with a certain sort of gravitational wave burst. This talk is based on joint work with Jeremy Butterfield, available at https://arxiv.org/abs/2106.01297.

« ProgramAlessandro Pizzo: Stability of gapped quantum systems under small perturbations
I will consider families of quantum lattice systems that have attracted much interest amongst people studying topological phases of matter. Their Hamiltonians are perturbations, by interactions of short range, of a Hamiltonian consisting of strictly local terms and with a (strictly positive) energy gap above its groundstate energy. I will review the main ideas of a novel method based on local LieSchwinger conjugations of the Hamiltonians associated with connected subsets of the lattice. By this method fermions and bosons are treated on the same footing, and our technique does not face a large field problem, even though bosons are involved.

« ProgramRodolfo Figari: Revisiting quantum mechanical zero range potentials and interactions
A careful look to the entire family of operators known as many center quantum point interaction Hamiltonians indicates that they do not show any singular or trivial behaviour when the positions of two or more scattering centres tend to coincide. In this sense, they appear to be a “by default" regularisation of the point interaction Hamiltonians defined via identical boundary conditions at each point of the scattering centre array. We will summarise some properties of this latter subfamily of Hamiltonians and we will try to clarify the renormalisation mechanism which makes them regular and physically relevant. We also investigate the reproducibility of the same regularisation mechanism in systems of many quantum particles interacting via zero range forces.

« ProgramSandro Donadi: Collapse dynamics are diffusive
Testing the limits of validity of the superposition principle is of crucial importance in the foundations of quantum mechanics and the development of quantum technologies. A way to quantify possible breakdowns of the superposition principle is given by collapse models. These models modify quantum mechanics by introducing a nonlinear interaction with a classical noise that induces collapse in space. The natural way of testing collapse models is through interferometric experiments of systems with large masses, which is challenging. For this reason, noninterferometric experiments were considered. These experiments exploit the fact that the noise responsible for the collapse induces a diffusion in momentum, in principle detectable even in localized systems by performing high precision position measurements. We first give a summary of the bounds on collapse models from noninterferometric experiments. Then we show how the diffusion in momentum is not just a property of collapse models but it is a universal feature of any dynamics inducing collapse in space. This implies that noninterferometric experiments test the quantum superposition principle in a stronger sense than one might suppose.

« ProgramNiklas Boers: Critical Transitions in the Earth System
In response to anthropogenic release of greenhouse gases, the Earth is warming at unprecedented rates. It has been suggested that several components of the Earth’s climate system may respond with abrupt transitions between alternative stable states in response to gradual changes in forcing. Based on the theory of stochastically forced dynamical systems and their bifurcations, a methodology is presented to measure changes in the stability of a given equilibrium state from observational time series. The method is applied to investigate if and how the stability of the Greenland Ice Sheets, a circulation system in the Atlantic Ocean, and the Amazon rainforest, has varied in the course of the last century.
« ProgramJean Bricmont: Why Bohm and only Bohm?
It is often claimed that there are three "realist" versions of quantum mechanics: the de BroglieBohm theory or Bohmian mechanics, the spontaneous collapse theories and the many worlds interpretation. We will explain why the two latter proposals suffer from serious defects coming from their ontology (or lack thereof) and that the many worlds interpretation is unable to account for the statistics encoded in the Born rule. The de BroglieBohm theory, on the other hand, has no problem of ontology and accounts naturally for the Born rule.
« ProgramLev Vaidman: Can Bohmian mechanics be the leading interpretation?
I believe this was the main question of Detlef Durr research. My views in favor and against Bohmian interpretation will be presented. The question of the possibility of observational differences between Bohmian mechanics and other interpretations (including experiments with unlimited technological power) will be analyzed. The light "surrealistic Bohmian trajectories" shed on this question will be discussed.
« ProgramLea Bossman: Edgeworth expansion for the weakly interacting Bose gas
We consider the ground state of a system of N weakly interacting bosons. We derive an Edgeworth expansion for the fluctuations of bounded onebody operators around the condensate, which yields corrections to a central limit theorem to any order in \(1/N\). This is joint work with Sören Petrat.
« ProgramJürg Fröhlich: The Classical Periphery of Quantum Mechanics  The Example of Particle Tracks in Detectors
In this talk I consider regimes of Quantum Mechanics that can be described in classical terms. Such regimes constitute what I call the "Classical Periphery/Skin of Quantum Mechanics." I won’t develop the general theory, but illustrate it in a study of tracks traced out by quantummechanical particles propagating in detectors. These tracks are close to classical particle trajectories. I will begin the talk with some general comments on the notion of "events" in Quantum Mechanics and their role in understanding "state reduction", as manifested in measurements and observations. My discussion is cast in what I have dubbed "ETHApproach to QM", which I regard as a cornerstone of Quantum Geometry.
« ProgramJoel Lebowitz (Zoom): Boltzmann's Entropy for Macroscopic Systems: Classical and Quantum
Boltzmann’s entropy is defined for individual macroscopic systems in a specified macrostate; equillibirum or not. In the latter case it satisfies the second law of thermodynamics which characterizes the time evolution of a typical isolated macroscopic system in a nonequilibrium macrostate. The time asymmetry of this observed evolution can be understood as arising from: a) the great disparity betreen microscopic and macroscopic sizes, b) initial conditions, and c) what we observe are typical behaviors — not all imaginable ones. While Boltzmann considered classical microscopic laws his conclusions also hold, with some modifications, for quantum systems.

« ProgramTim Maudlin: On the Emergence of Relativistic Structure from Discrete SpaceTime with a Global Foliation
The empirical success of Special and General Relativity, and of theories that incorporate Relativistic symmetries, argues that the Relativistic account of spacetime structure must approximate the truth. But on the other hand, the confirmed violations of Bell’s Inequality for experiments done at spacelike separation equally appears to argue for some global foliation of spacetime that does not appear in the Relativistic theory.
