Time-delayed feedback turns Arrhenius escape logarithmic
Roy Podgaetsky, Vishwajeet Kumar, Arnab Pal +1
Thermal escape is governed by the Arrhenius law, where the mean escape time scales exponentially with the barrier height. We show that the non-Markovianity induced by time-delayed…
Speeding up Brownian escape via intermediate finite potential barriers
Vishwajeet Kumar, Ohad Shpielberg, Arnab Pal
The mean first-passage time (MFPT) for a Brownian particle to surmount a potential barrier of height is a fundamental quantity governing a wide array of physical and chemical…
Inferring intermediate states by leveraging the many-body Arrhenius law
Vishwajeet Kumar, Arnab Pal, Ohad Shpielberg
Metastable states appear as long-lived intermediate states in various natural transport phenomena which are governed by energy landscapes. As such, these intermediate metastable st…
Systematic analysis of critical exponents in continuous dynamical phase transitions of weak noise theories
Timo Schorlepp, Ohad Shpielberg
Dynamical phase transitions are nonequilibrium counterparts of thermodynamic phase transitions and share many similarities with their equilibrium analogs. In continuous phase trans…
Emerging universality classes in thermally-assisted activation of interacting diffusive systems: A perturbative hydrodynamic approach
Vishwajeet Kumar, Arnab Pal, Ohad Shpielberg
Thermal activation of a particle from a deep potential trap follows the Arrhenius law. Recently, this result was generalized for interacting diffusive particles in the trap, reveal…
Arrhenius law for interacting diffusive systems
Vishwajeet Kumar, Arnab Pal, Ohad Shpielberg
Finding the mean time it takes for a particle to escape from a meta-stable state due to thermal fluctuations is a fundamental problem in physics, chemistry and biology. For weak th…
Universal entanglement entropy in the ground state of biased bipartite systems
Ohad Shpielberg
The ground state entanglement entropy is studied in a many-body bipartite quantum system with either a single or multiple conserved quantities. It is shown that the entanglement en…
Power law decay of entanglement quantifiers in a single agent to a many body system coupling
Ohad Shpielberg
Manipulating many body quantum systems is a challenge. A useful way to achieve it would be to entangle the system to a diluted system, with a small particle number. Preparation of…
Thermodynamic uncertainty relations for many-body systems with fast jump rates and large occupancies
Ohad Shpielberg, Arnab Pal
A universal large theory of nonequilibrium fluctuations emerges in the limit of fast jump rates and large occupancies. We use this theory to derive a set of coarse gr…
Uncertainty Relations for Mesoscopic Coherent Light
Ariane Soret, Ohad Shpielberg, Eric Akkermans
Thermodynamic uncertainty relations unveil useful connections between fluctuations in thermal systems and entropy production. This work extends these ideas to the disparate field o…
Imitating non-equilibrium steady states using time-varying equilibrium force in many-body diffusive systems
Ohad Shpielberg, Takahiro Nemoto
An equivalence between non equilibrium steady states (NESS) driven by a time-independent force and stochastic pumps (SP) stirred by a time-varying conservative force is studied for…
Diffusion and entanglement in open quantum systems
Ohad Shpielberg
The macroscopic fluctuation theory provides a complete hydrodynamic description of non-equilibrium classical diffusive systems. As a first step towards a diffusive theory of open q…
Universality in dynamical phase transitions of diffusive systems
Ohad Shpielberg, Takahiro Nemoto, João Caetano
Universality, where microscopic details become irrelevant, takes place in thermodynamic phase transitions. The universality is captured by a singular scaling function of the thermo…
Transport in quantum chains under strong monitoring
D. Bernard, T. Jin, O. Shpielberg
We study the transport properties of quantum 1D systems under strong monitoring. The quantum Zeno effect inhibits transport and induces localization. Beyond the Zeno freezing and o…
Geometrical Interpretation of Dynamical Phase Transitions in Boundary Driven Systems
Ohad Shpielberg
Dynamical phase transitions are defined as non-analytic points of the large deviation function of current fluctuations. We show that for boundary driven systems, many dynamical pha…
Numerical Study of Continuous and Discontinuous Dynamical Phase Transitions for Boundary Driven Systems
Ohad Shpielberg, Yaroslav Don, Eric Akkermans
The existence and search for thermodynamic phase transitions is of unfading interest. In this paper, we present numerical evidence of dynamical phase transitions occurring in bound…

Ohad Shpielberg, Eric Akkermans
A stability analysis of out of equilibrium and boundary driven systems is presented. It is performed in the framework of the hydrodynamic macroscopic fluctuation theory and assumin…
Disorder induced power-law response of a superconducting vortex on a plane
N. Shapira, Y. Lamhot, O. Shpielberg +6
We report drive-response experiments on individual superconducting vortices on a plane, a realization for a 1+1-dimensional directed polymer in random media. For this we use magnet…
Universal current fluctuations in the symmetric exclusion process and other diffusive systems
Eric Akkermans, Thierry Bodineau, Bernard Derrida +1
We show, using the macroscopic fluctuation theory of Bertini, De Sole, Gabrielli, Jona-Lasinio, and Landim, that the statistics of the current of the symmetric simple exclusion pro…
