TL;DR: In this article, the authors studied the dynamics of isolated quantum many-body systems whose Hamiltonian is switched between two different operators periodically in time, and established conditions on the spectral properties of the two Hamiltonians for the system to localize in energy space.

TL;DR: The possibility that quantum processing with nuclear spins might be operative in the brain is proposed and then explored, and the Posner molecule is identified as the unique molecule that can protect the neural qubits on very long times and thereby serve as a (working) quantum-memory.

TL;DR: By introducing the scalar potential as modification in the mass term of the Klein-Gordon equation, the influence of a Coulomb-type potential on the Klein -Gordon oscillator was investigated in this article.

TL;DR: In this paper, a new model of nonlinear electrodynamics with two parameters is investigated, where the electric field of a point-like charge is not singular at the origin and there is the finiteness of the static electric energy of pointlike charged particles.

TL;DR: In this paper, the authors formulate a general gauging framework, characterize the anyon structure of twist liquids, and provide solvable lattice models that capture the gauging phase transitions, explicitly demonstrating the measuring of the Z 2 -symmetric toric code, S O ( 2 N ) 1 and S U ( 3 ) 1 states as well as the S 3 -symetric S O( 8 ) 1 state and a non-Abelian chiral state.

TL;DR: In this article, the authors show that MBL in translation-invariant systems with two or more very different energy scales is less robust than perturbative arguments suggest, possibly pointing to the importance of nonperturbative effects which induce delocalization in the thermodynamic limit.

TL;DR: In this paper, the authors studied a two-state vector formalism (TSVF) where the choice of the experimenter has been encrypted within the weak measurement's outcomes, even before the experimenters themselves know what their choice will be.

TL;DR: Using the mimetic matter approach, this paper studied F (R ) gravity with scalar potential and Lagrange multiplier constraint and showed that for a given F ( R ) gravity and for suitably chosen mimetic potential, it is possible to realize inflationary cosmology consistent with Planck observations.

TL;DR: In this paper, a novel Wetterich-type functional renormalization group equation for gravity is constructed, which encodes the gravitational degrees of freedom in terms of gauge-invariant fluctuation fields.

TL;DR: In this article, the authors introduce a way to extend the set of symmetric Projected Entangled Pair States (PEPS) in order to include local gauge invariance and investigate lattice gauge theories with fermionic matter.

TL;DR: In this article, the experimental evidences of conductive filaments, the transport and switching mechanisms, and the memory performances and enhancing methods of perovskite oxide based filamentary RRAM cells have been summarized and discussed.

TL;DR: In this article, a magnetically charged regular black hole in general relativity was obtained, which was constructed on the basis of three conditions: the Maxwell asymptotic in the weak electromagnetic field limit; the presence of vacuum birefringence phenomenon; and satisfying the weak energy condition (WEC).

TL;DR: In this paper, the oscillatory component of the quantum state density in a separable (integrable) system can develop rather strong finite-size precursors of excited-state quantum phase transition (ESQPT) expressed as singularities in the state density.

TL;DR: In this article, the authors consider a many-body generalization of the Kapitza pendulum and show that it is dynamically stable to periodic drives with finite frequency and amplitude.

TL;DR: In this paper, the authors show how to make such expansions meaningful via their completion into resurgent transseries, encoding both perturbative and nonperturbative data, which can be used to define gauge theory for any complex value of N.

TL;DR: In this paper, a time dependent Schrodinger equation for the system composed by Hawking radiation and BH quasi-normal modes is presented, where the physical state and the correspondent wave function are written in terms of a unitary evolution matrix instead of a density matrix.

TL;DR: In this paper, a set of quantum hydrodynamic equations for spin-up and spin-down electron evolution in a uniform external magnetic field are presented, assuming that plasmas are placed in an uniform magnetic field.

TL;DR: In this article, the steady state of a three-level system in contact with a non-equilibrium environment, which is composed of two independent heat baths at different temperatures, was studied.

TL;DR: In this paper, the authors consider Dirac semimetals with two Dirac points ± K and consider the case when the deformations are caused by the dislocations, and show that in the presence of external electric field the quasiparticles/holes are pumped from vacuum along the dislocation.

TL;DR: In this article, a new class of information-theoretic uncertainty relations (ITURs) based on information theory for both discrete and continuous distribution functions are briefly reviewed and extended to account for (differential) Renyi entropy and its related entropy power.

TL;DR: In this paper, a LC circuit is used to induce the necessary interaction between flux qubits, each magnetically coupling to a nitrogen-vacancy center ensemble (NVCE).

TL;DR: In this article, a complete description of vector Bessel (vortex) beams in the context of the generalized Lorenz-Mie theory (GLMT) for the electromagnetic resonance scattering by a dielectric sphere is presented, using the method of separation of variables and the subtraction of a non-resonant background (corresponding to a perfectly conducting sphere of the same size) from the standard Mie scattering coefficients.
