Effective Hamiltonian approach to kinetic Ising models: Application to an infinitely long-range Husimi-Temperley model

V. I. Tokar

The probability distribution (PD) of spin configurations in kinetic Ising models has been cast in the form of the canonical Boltzmann PD with a time-dependent effective Hamiltonian…

Optimal time-entropy bounds and speed limits for Brownian thermal shortcuts

Luís Barbosa Pires, Rémi Goerlich, Arthur Luna da Fonseca +4

By controlling in real-time the variance of the radiation pressure exerted on an optically trapped microsphere, we engineer temperature protocols that shortcut thermal relaxation w…

Exact renormalization group equation for lattice Ginzburg-Landau models adapted to the solution in the local potential approximation

V. I. Tokar

The Wilson Green's function approach and, alternatively, Feynman's diffusion equation and the Hori representation have been used to derive an exact functional RG equation (EFRGE) t…

Renormalization group approach to unified description of continuous and the first order phase transitions: application to the Blume-Capel model

V. I. Tokar

The renormalization group (RG) equation in the self-consistent local potential approximation (SC-LPA) suggested earlier for the description of continuous phase transitions in latti…

Noise and ergodic properties of Brownian motion in an optical tweezer: looking at the crossover between Wiener and Ornstein-Uhlenbeck processes

Rémi Goerlich, Minghao Li, Samuel Albert +3

We characterize throughout the spectral range of an optical trap the nature of the noise at play and the ergodic properties of the corresponding Brownian motion of an overdamped tr…

Self-consistent renormalization group approach to continuous phase transitions in alloys. Application to ordering in -brass

V. I. Tokar

A self-consistent (SC) renormalization group approach of the effective medium kind has been developed and applied to the solution of the Ising model (IM). A renormalization group e…

Effective medium approach in the renormalization group theory of phase transitions

V. I. Tokar

An effective medium approach similar to the coherent potential approximation (CPA) in the theory of disordered alloys and to the DMFT has been extended to the renormalization group…

Optimal protocols and universal time-energy bound in Brownian thermodynamics

Yoseline Rosales-Cabara, Giovanni Manfredi, Gabriel Schnoering +3

We propose an optimization strategy to control the dynamics of a stochastic system transferred from one thermal equilibrium to another and apply it experimentally to a Brownian par…

Does a Single Eigenstate of a Hamiltonian Encode the Critical Behaviour of its Finite-Temperature Phase Transition?

Keith R. Fratus, Syrian V. Truong

Recent work on the subject of isolated quantum thermalization has suggested that an individual energy eigenstate of a non-integrable quantum system may encode a significant amount…

Phase-change switching in 2D via soft interactions

Rogelio Díaz-Méndez, Guido Pupillo, Fabio Mezzacapo +3

We present a new type of phase-change behavior relevant for information storage applications, that can be observed in 2D systems with cluster-forming ability. The temperature-based…

Event-Driven Monte Carlo: exact dynamics at all time-scales for discrete-variable models

Alejandro Mendoza-Coto, Rogelio Díaz-Méndez, Guido Pupillo

We present an algorithm for the simulation of the exact real-time dynamics of classical many-body systems with discrete energy levels. In the same spirit of kinetic Monte Carlo met…

Dynamics of entanglement entropy and entanglement spectrum crossing a quantum phase transition

Elena Canovi, Elisa Ercolessi, Piero Naldesi +2

We study the time evolution of entanglement entropy and entanglement spectrum in a finite-size system which crosses a quantum phase transition at different speeds. We focus on the…

Fluctuation-Dissipation Theorem in an Isolated System of Quantum Dipolar Bosons after a Quench

Ehsan Khatami, Guido Pupillo, Mark Srednicki +1

We examine the validity of fluctuation-dissipation relations in isolated quantum systems taken out of equilibrium by a sudden quench. We focus on the dynamics of trapped hard-core…

From laser cooling to aging: a unified Levy flight description

Eric Bertin, Francois Bardou

Intriguing phenomena such as subrecoil laser cooling of atoms, or aging phenomenon in glasses, have in common that the systems considered do not reach a steady-state during the exp…

Electronic lifetimes in ballistic quantum dots electrostatically coupled to metallic environments

F. Guinea, R. A. Jalabert, F. Sols

We calculate the lifetime of low-energy electronic excitations in a two-dimensional quantum dot near a metallic gate. We find different behaviors depending on the relative values o…

Compression modulus of macroscopic fiber bundles

P. Beckrich, G. Weick, C. M. Marques +1

We study dense, disordered stacks of elastic macroscopic fibers. These stacks often exhibit non-linear elasticity, due to the coupling between the applied stress and the internal d…

In-plane magnetic reorientation in coupled ferro- and antiferromagnetic thin films

P. J. Jensen, H. Dreysse

By studying coupled ferro- (FM) and antiferromagnetic (AFM) thin film systems, we obtain an in-plane magnetic reorientation as a function of temperature and FM film thickness. The…
