Self-organizing reinforcement learning: a learner-free swarm approaches the explore-exploit optimum
The explore/exploit trade-off is the core problem of reinforcement learning (RL).Exact probability laws of random inner products: Dirichlet splines, overlaps, uncertainty, and Bargmann invariants
Inner products of random matrices and random quantum states---such as orbital inner products, expectation values, overlaps, and cyclic Bargmann invariants---are shown to follow from two underlying…Response theory at low temperature for weakly interacting quantum spin systems
Recent work by Greenblatt, Lange, Marcelli, and Porta (Commun.Spatial Discretization Error for Quantum Chemistry Simulation
Nonrelativistic quantum chemistry is based on the Schrödinger equation in continuous, unbounded space.Upper Bound on the Correlation Energy of a Dense Fermi Gas in the Thermodynamic Limit
We prove that the random phase approximation provides an upper bound on the correlation energy of a three-dimensional, weakly interacting, Fermi gas in the thermodynamic limit at high density.De Finetti Structures in Networks of Quantum Systems
Consider $N$ identical quantum systems at the vertices of a graph, interacting via pairwise edge couplings.\textit{In situ} certification of multiparticle indistinguishability in a generic interferometer
We propose a scalable and efficient \textit{in situ} method for assessing the multiparticle indistinguishability of identical bosons or fermions in quantum interference experiments on linear…Topological Quantum Gates on FCIs with Bounded Quantum Geometry
Two-band 2D fractional Chern insulators (FCIs) have recently been shown, in principle, to admit unusual anyonic order, associated with Bloch Hopfions localized in momentum space.Upper bounds on the number of images produced by point-mass lenses at different distances
If a light source is sequentially lensed by $n$ intervening point-mass lenses at distinct distances, the number of isolated images for a generic source position cannot be greater than $2\cdot…Where should we look for the deviation from quantum mechanics?
We argue that the experimental measurement of the lifetime and decay law of metastable helium is a promising way to find a deviation from quantum mechanics.An example of a non-sofic hyperbolic group
We construct a torsion-free, two-dimensional, word-hyperbolic group which is not sofic.On the relationship between the POVM framework and the no-signaling hypothesis
The quantum foundations literature contains dozens of "no-signaling" arguments that rely on the Born rule or, more generally, the positive operator-valued measure (POVM) framework to show that the…Anticommuting Displacement Operators, Exact Pauli Algebras,and the Singlet State from the Oscillator Vacuum
We give an explicit construction of a pair of anticommuting Weyl displacement operators for a harmonic oscillator and use bounded functional calculus to obtain exact dichotomic representatives of…Partially isophase electro-magnetic configurations
Separation of variables in Schrödinger equation allows an infinite-dimensional family of physically distinct field configurations that are dynamically indistinguishable in one selected sector…Recursive Operator Localization and Spectral Gap Descent via the Geometry of Local Spectral Expansion
We introduce Recursive Operator Localization (ROL), a framework for constructing hierarchies of local energy problems linked by linear maps between Hilbert spaces.Rapid mixing within a phase for Ising models
We study Glauber dynamics for Ising measures conditioned to have a sufficiently large majority of $+1$ spins.Translation-Invariant Pure States with Exotic Half-Chain Factors
We construct translation-invariant pure quasifree fermionic states on the one-dimensional lattice whose half-chain von Neumann algebras are hyperfinite factors of type $\mathrm{II}_\infty$ or…Singular wave functions and quantum collapse in inverse-power potentials
Quantum collapse (QC) occurs under the action of the inverse-power potential U(r)=-U_{0}/(2r^{n}) in the framework of the Schroedinger equation.Operator-Space Entanglement Entropy in Random Fermionic Gaussian Dynamics
We study the von Neumann operator-space entanglement entropy (OSEE) of initial product operators evolved under random gaussian dynamics, as modeled by a Brownian SYK$_2$ model.Classical Capacity of Single-Mode Bosonic Gaussian Channels
The classical capacity of a noisy optical channel is the maximum rate at which information can be transmitted reliably, given a constraint on the mean input energy.
