Wasserstein-2 gradient flows and the geometry of entropy production in classical and quantum stochastic thermodynamics
Olga Movilla Miangolarra, Ralph Sabbagh, Artemy Kolchinsky
The second law does more than set the direction of thermodynamic evolution: it endows nonequilibrium transformations with an underlying geometry. In this work, we provide a unified…
Quo vadis, stochastic thermodynamics?
Jan Korbel, Artemy Kolchinsky, Sarah A. M. Loos +4
Stochastic thermodynamics is a framework for describing non-equilibrium processes at the level of fluctuating trajectories, where the state of a system evolves as a stochastic time…
On a time-resolved interpretation of the Husimi function
Ralph Sabbagh, Olga Movilla Miangolarra, Tryphon T. Georgiou
In this Letter, we interpret the Husimi function as the conditional probability density of continuously measuring a stream of constant position and momentum outcomes, indefinitely.…
Regulation of a continuously monitored quantum harmonic oscillator with inefficient detectors
Ralph Sabbagh, Olga Movilla Miangolarra, Tryphon T. Georgiou
We study the control problem of regulating the purity of a quantum harmonic oscillator in a Gaussian state via weak measurements. Specifically, we assume time-invariant Hamiltonian…
Quantum Schrodinger bridges: large deviations and time-symmetric ensembles
Olga Movilla Miangolarra, Ralph Sabbagh, Tryphon T. Georgiou
Quantum counterparts of Schrodinger's classical bridge problem have been around for the better part of half a century. During that time, several quantum approaches to this multifac…
An excursion onto Schrödinger's bridges: Stochastic flows with spatio-temporal marginals
Asmaa Eldesoukey, Olga Movilla Miangolarra, Tryphon T. Georgiou
The purpose of the present work is to expand substantially the type of control and estimation problems that can be addressed following the paradigm of Schrödinger bridges, by incor…
Wasserstein speed limits for Langevin systems
Ralph Sabbagh, Olga Movilla Miangolarra, Tryphon T. Georgiou
Physical systems transition between states with finite speed that is limited by energetic costs. In this work, we derive bounds on transition times for general Langevin systems tha…
A matching principle for power transfer in Stochastic Thermodynamics
Olga Movilla Miangolarra, Amirhossein Taghvaei, Tryphon T. Georgiou
Gradients in temperature and particle concentration fuel many processes in the physical and biological world. In the present work we study a thermodynamic engine powered by anisotr…
Minimal entropy production in anisotropic temperature fields
Olga Movilla Miangolarra, Amirhossein Taghvaei, Tryphon T. Georgiou
Anisotropy of temperature fields, chemical potentials and ion concentration gradients provide the fuel that feeds dynamical processes that sustain life. Dynamical flows in respecti…
Inertialess Gyrating Engines
Jordi Ventura Siches, Olga Movilla Miangolarra, Amirhossein Taghvaei +2
A typical model for a gyrating engine consists of an inertial wheel powered by an energy source that generates an angle-dependent torque. Examples of such engines include a pendulu…
Stochastic thermodynamic engines under time-varying temperature profile
Rui Fu, Olga Movilla Miangolarra, Amirhossein Taghvaei +2
In the present paper, we study the power output and efficiency of overdamped stochastic thermodynamic engines that are in contact with a heat bath having a temperature that varies…
Thermodynamic engine powered by anisotropic fluctuations
Olga Movilla Miangolarra, Amirhossein Taghvaei, Yongxin Chen +1
The purpose of this work is to present the concept of an autonomous Stirling-like engine powered by anisotropy of thermodynamic fluctuations. Specifically, simultaneous contact of…
Energy harvesting from anisotropic fluctuations
Olga Movilla Miangolarra, Amirhossein Taghvaei, Rui Fu +2
We consider a rudimentary model for a heat engine, known as the Brownian gyrator, that consists of an overdamped system with two degrees of freedom in an anisotropic temperature fi…
On the relation between information and power in stochastic thermodynamic engines
Amirhossein Taghvaei, Olga Movilla Miangolarra, Rui Fu +2
The common saying, that information is power, takes a rigorous form in stochastic thermodynamics, where a quantitative equivalence between the two helps explain the paradox of Maxw…
Harvesting energy from a periodic heat bath
Rui Fu, Olga Movilla Miangolarra, Amirhossein Taghvaei +2
The context of the present paper is stochastic thermodynamics - an approach to nonequilibrium thermodynamics rooted within the broader framework of stochastic control. In contrast…
