Title: Quantum forces in cavities
Authors: E. Cavalcanti and A.P.C. Malbouisson
Abstract summary: We compute the quantum pressure on the boundaries of a compactified space in a thermal bath. Considering both periodic and antiperiodic boundary conditions in the cavity, we discuss the attractive or repulsive character of the quantum forces.

Abstract: We present an alternative route to investigate quantum forces in a cavity, for both a free scalar field and a free fermionic field. Considering a generalized Matsubara procedure, we compute the quantum pressure on the boundaries of a compactified space in a thermal bath. Also, considering both periodic and antiperiodic boundary conditions in the cavity, we discuss the attractive or repulsive character of the quantum forces. Our results highlight the relevance and interdisciplinarity of the generalized Matsubara procedure as a theoretical platform to manage quantum phenomena in nontrivial topologies.

Emergent Fracton Hydrodynamics in the Fractional Quantum Hall Regime of Ultracold Atoms [41.94295877935867]
We show that in the lowest Landau level the system generically relaxes subdiffusively. The slow relaxation is understood from emergent conservation laws of the total charge. We discuss the prospect of rotating quantum gases as well as ultracold atoms in optical lattices for observing this unconventional relaxation dynamics.

Dirac Equation with Space Contributions Embedded in a Quantum-Corrected Gravitational Field [0.0]
The Dirac equation is considered with the recently proposed generalized gravitational interaction (Kepler or Coulomb) We discuss several known generalizations of the Coulomb potential within this formulation in terms of certain Heun functions. The impossibility of solving our equation for the quantum-corrected Coulomb terms using known exact or quasi-exact nonperturbative analytical techniques is discussed.

Embezzling entanglement from quantum fields [41.94295877935867]
Embezzlement of entanglement refers to the counterintuitive possibility of extracting entangled quantum states from a reference state of an auxiliary system. We uncover a deep connection between the operational task of embezzling entanglement and the mathematical classification of von Neumann algebras.

Matter relative to quantum hypersurfaces [44.99833362998488]
We extend the Page-Wootters formalism to quantum field theory. By treating hypersurfaces as quantum reference frames, we extend quantum frame transformations to changes between classical and nonclassical hypersurfaces.

Quantum Reference Frames at the Boundary of Spacetime [0.0]
An analysis is given of the local phase space of gravity coupled to matter to second order in perturbation theory. The boundary modes take the role of reference frames for both diffeomorphisms and internal Lorentz rotations. A multi-fingered Schr"odinger equation determines the relational evolution of the quantum states in the bulk.

Measurement phase transitions in the no-click limit as quantum phase transitions of a non-hermitean vacuum [77.34726150561087]
We study phase transitions occurring in the stationary state of the dynamics of integrable many-body non-Hermitian Hamiltonians. We observe that the entanglement phase transitions occurring in the stationary state have the same nature as that occurring in the vacuum of the non-hermitian Hamiltonian.

Scalar-Mediated Quantum Forces Between Macroscopic Bodies and Interferometry [0.0]
We study the quantum force between classical objects mediated by massive scalar fields bilinearly coupled to matter. We show that the quantum pressure inside a Dirichlet sphere is finite -- up to renormalizable divergences. In plane-point geometry we show how to compute the contribution of the quantum force to the phase shift observable in atom interferometers.
