Recent Submissions

Thermodynamic control  an old paradigm with new applications
(20200624)Tremendous research efforts have been invested in exploring and designing socalled shortcuts to adiabaticity. These are finitetime processes that produce the same final states that would result from infinitely slow ... 
Quantum stochastic thermodynamic on harmonic networks
(IOP, 20160104)Fluctuation theorems are symmetry relations for the probability to observe an amount of entropy production in a finitetime process. In a recent paper Pigeon et al (2016 New. J. Phys. 18 013009) derived fluctuation theorems ... 
Controlling the speed and trajectory of evolution with counterdiabatic driving
(Cold Spring Harbor Laboratory (CHS), 20200604)The pace and unpredictability of evolution are critically relevant in a variety of modern challenges: combating drug resistance in pathogens and cancer, understanding how species respond to environmental perturbations like ... 
Quantum speed limits and the maximal rate of quantum learning
(20170614)The BremermannBekenstein bound is a fundamental bound on the maximal rate with which information can be transmitted. However, its derivation relies on rather weak estimates and plausibility arguments, which make the ... 
Quantum speed limits and the maximal rate of information production
(American Physical Society (APS), 20200214)The BremermannBekenstein bound sets a fundamental upper limit on the rate with which information can be processed. However, the original treatment heavily relies on cosmological properties and plausibility arguments. In ... 
Repeatability of measurements: NonHermitian observables and quantum Coriolis force
(American Physical Society (APS), 20160826)A noncommuting measurement transfers, via the apparatus, information encoded in a system's state to the external “observer.” Classical measurements determine properties of physical objects. In the quantum realm, the very ... 
Information free energy for nonequilibrium states
(20120118)We introduce an information free energy for thermodynamic systems driven by external timedependent parameters. We show that the latter is a nonequilibrium state function and that it is a natural generalization of the usual ... 
Quantum work distribution for a driven diatomic molecule
(Elsevier, 20150113)We compute the quantum work distribution for a driven Morse oscillator. To this end, we solve the timedependent dynamics for a scaleinvariant process, from which the exact expressions for the transition probabilities are ... 
Foundations of statistical mechanics from symmetries of entanglement
(IOP, 20160609)Envariance—entanglement assisted invariance—is a recently discovered symmetry of composite quantum systems. We show that thermodynamic equilibrium states are fully characterized by their envariance. In particular, the ... 
Quantum work statistics of charged Dirac particles in timedependent fields
(American Physical Society (APS), 20150928)The quantum Jarzynski equality is an important theorem of modern quantum thermodynamics. We show that the Jarzynski equality readily generalizes to relativistic quantum mechanics described by the Dirac equation. After ... 
Quantum fluctuation theorems in the strong damping limit
(IOP, 20110421)We consider a driven quantum particle in the strong friction regime described by the quantum Smoluchowski equation. We derive Crooks and Jarzynski type relations for the reduced quantum system by properly generalizing the ... 
Fast forward to the classical adiabatic invariant
(American Physical Society (APS), 20170310)We show how the classical action, an adiabatic invariant, can be preserved under nonadiabatic conditions. Specifically, for a timedependent Hamiltonian H=p²/2m+U(q,t) in one degree of freedom, and for an arbitrary choice ... 
Efficiency of Harmonic Quantum Otto Engines at Maximal Power
(MDPI, 20181215)Recent experimental breakthroughs produced the first nano heat engines that have the potential to harness quantum resources. An instrumental question is how their performance measures up against the efficiency of classical ... 
PTsymmetric slowing down of decoherence
(American Physical Society (APS), 20161027)We investigate PTsymmetric quantum systems ultraweakly coupled to an environment. We find that such open systems evolve under PTsymmetric, purely dephasing and unital dynamics. The dynamical map describing the evolution ... 
KibbleZurek scaling of the irreversible entropy production
(American Physical Society (APS), 20171116)If a system is driven at finite rate through a phase transition by varying an intensive parameter, the order parameter shatters into finite domains. The KibbleZurek mechanism predicts the typical size of these domains, ... 
Quantum fluctuation theorem for error diagnostics in quantum annealers
(Springer Nature, 20181121)Near term quantum hardware promises unprecedented computational advantage. Crucial in its development is the characterization and minimization of computational errors. We propose the use of the quantum fluctuation theorem ... 
Jarzynski Equality for Driven Quantum Field Theories
(American Physical Society (APS), 20180227)The fluctuation theorems, and in particular, the Jarzynski equality, are the most important pillars of modern nonequilibrium statistical mechanics. We extend the quantum Jarzynski equality together with the twotime ... 
Interference of identical particles and the quantum work distribution
(American Physical Society (APS), 20141215)Quantummechanical particles in a confining potential interfere with each other while undergoing thermodynamic processes far from thermal equilibrium. By evaluating the corresponding transition probabilities between ... 
Shortcuts to adiabaticity: suppression of pair production in driven Dirac dynamics
(IOP, 20151221)Achieving effectively adiabatic dynamics in finite time is a ubiquitous goal in virtually all areas of modern physics. Socalled shortcuts to adiabaticity refer to a set of methods and techniques that allow us to produce ... 
Precision thermometry and the quantum speed limit
(IOP, 20180205)We assess precision thermometry for an arbitrary single quantum system. For a ddimensional harmonic system we show that the gap sets a single temperature that can be optimally estimated. Furthermore, we establish a simple ...
