Anomalous discharging of quantum batteries: the ergotropic Mpemba effect
Ivan Medina, Oisín Culhane, Felix C. Binder +2
Anomalous thermal relaxation is ubiquitous in nonequilibrium statistical mechanics. An emblematic example of this is the Mpemba effect, where an initially ``hot'' system cools fast…
The role of correlations in a sequence of quantum observations on empirical measures
Joseph A. Smiga, Gabriel T. Landi
The outcome of continuously measuring a quantum system is a string of data whose intricate correlation properties reflect the underlying quantum dynamics. In this paper we study th…
Eigenoperator approach to Schrieffer-Wolff perturbation theory and dispersive interactions
Gabriel T. Landi
Modern quantum physics is very modular: we first understand basic building blocks (``XXZ Hamiltonian'' ``Jaynes-Cummings'' etc.) and then combine them to explore novel effects. A t…
Time-resolved Stochastic Dynamics of Quantum Thermal Machines
Abhaya S. Hegde, Patrick P. Potts, Gabriel T. Landi
Steady-state quantum thermal machines are typically characterized by a continuous flow of heat between different reservoirs. However, at the level of discrete stochastic realizatio…
Role of Quantum Coherence in Kinetic Uncertainty Relations
Kacper Prech, Patrick P. Potts, Gabriel T. Landi
The Kinetic Uncertainty Relation (KUR) bounds the signal-to-noise ratio of stochastic currents in terms of the number of transitions per unit time, known as the dynamical activity.…
Collisional thermometry for Gaussian systems
Gabriel O. Alves, Marcelo A. F. Santos, Gabriel T. Landi
We investigate a quantum thermometry scheme based collision model with Gaussian systems. A key open question of these schemes concerns the scaling of the Quantum Fisher Information…
Waiting time statistics for a double quantum dot coupled with an optical cavity
Luis F. Santos, Gabriel T. Landi
A double quantum dot coupled to an optical cavity is a prototypical example of a non-trivial open quantum system. Recent experimental and theoretical studies show that this system…
Quantum stochastic thermodynamics in the mesoscopic-leads formulation
Laetitia P. Bettmann, Michael J. Kewming, Gabriel T. Landi +2
We introduce a numerical method to sample the distributions of charge, heat, and entropy production in open quantum systems coupled strongly to macroscopic reservoirs, with both te…
Universal energy fluctuations in inelastic scattering processes
Samuel L. Jacob, John Goold, Gabriel T. Landi +1
Quantum scattering is used ubiquitously in both experimental and theoretical physics across a wide range of disciplines, from high-energy physics to mesoscopic physics. In this wor…
Queued quantum collision models
Guilherme Fiusa, Gabriel T. Landi
Collision models describe the sequential interactions of a system with independent ancillas. Motivated by recent advances in neutral atom arrays, in this Letter we investigate a mo…
Parameter estimation for quantum jump unraveling
Marco Radaelli, Joseph A. Smiga, Gabriel T. Landi +1
We consider the estimation of parameters encoded in the measurement record of a continuously monitored quantum system in the jump unraveling, corresponding to a single-shot scenari…
Fisher information rates in sequentially measured quantum systems
Eoin O'Connor, Steve Campbell, Gabriel T. Landi
We consider the impact that temporal correlations in the measurement statistics can have on the achievable precision in a sequential metrological protocol. In this setting, and for…
