Characterizing the performance of heat rectifiers
Shishir Khandelwal, Martí Perarnau-Llobet, Stella Seah +2
A physical system connected to two thermal reservoirs at different temperatures is said to act as a heat rectifier when it is able to bias the heat current in a given direction, si…
Uninformed Bayesian Quantum Thermometry
Julia Boeyens, Stella Seah, Stefan Nimmrichter
We study the Bayesian approach to thermometry with no prior knowledge about the expected temperature scale, through the example of energy measurements on fully or partially thermal…
Fundamental limits in Bayesian thermometry and attainability via adaptive strategies
Mohammad Mehboudi, Mathias R. Jørgensen, Stella Seah +3
We investigate the limits of thermometry using quantum probes at thermal equilibrium within the Bayesian approach. We consider the possibility of engineering interactions between t…
Quantum speed-up in collisional battery charging
Stella Seah, Martí Perarnau-Llobet, Géraldine Haack +2
We present a collision model for the charging of a quantum battery by identical nonequilibrium qubit units. When the units are prepared in a mixture of energy eigenstates, the ener…
Surpassing the Thermal Cramer-Rao Bound with Collisional Thermometry
Angeline Shu, Stella Seah, Valerio Scarani
In collisional thermometry, a system in contact with the thermal bath is probed by a stream of ancillas. Coherences and collective measurements were shown to improve the Fisher inf…
Maxwell's lesser demon: a quantum engine driven by pointer measurements
Stella Seah, Stefan Nimmrichter, Valerio Scarani
We discuss a self-contained spin-boson model for a measurement-driven engine, in which a demon generates work from thermal excitations of a quantum spin via measurement and feedbac…
Collisional quantum thermometry
Stella Seah, Stefan Nimmrichter, Daniel Grimmer +3
We introduce a general framework for thermometry based on collisional models, where ancillas probe the temperature of the environment through an intermediary system. This allows fo…
Almost thermal operations: inhomogeneous reservoirs
Angeline Shu, Yu Cai, Stella Seah +2
The resource theory of thermal operations explains the state transformations that are possible in a very specific thermodynamic setting: there is only one thermal bath, auxiliary s…
Nonequilibrium Dynamics with Finite-Time Repeated Interactions
Stella Seah, Stefan Nimmrichter, Valerio Scarani
We study quantum dynamics in the framework of repeated interactions between a system and a stream of identical probes. We present a coarse-grained master equation that captures the…
Violation of all the second laws of thermal operations by inhomogeneous reservoirs
Angeline Shu, Yu Cai, Stella Seah +2
In the resource theory of thermodynamics, the decrease of the free energy based on von Neumann entropy is not a sufficient condition to determine free evolution. Rather, a whole fa…
Quantum Rotor Engines
Stella Seah, Stefan Nimmrichter, Alexandre Roulet +1
This chapter presents autonomous quantum engines that generate work in the form of directed motion for a rotor. We first formulate a prototypical clock-driven model in a time-depen…
Refrigeration beyond weak internal coupling
Stella Seah, Stefan Nimmrichter, Valerio Scarani
We investigate the performance of a three-spin quantum absorption refrigerator using a refined open quantum system model valid across all inter-spin coupling strengths. It describe…
Work production of quantum rotor engines
Stella Seah, Stefan Nimmrichter, Valerio Scarani
We study the mechanical performance of quantum rotor heat engines in terms of common notions of work using two prototypical models: a mill driven by the heat flow from a hot to a c…
Autonomous Rotor Heat Engine
Alexandre Roulet, Stefan Nimmrichter, Juan Miguel Arrazola +2
The triumph of heat engines is their ability to convert the disordered energy of thermal sources into useful mechanical motion. In recent years, much effort has been devoted to gen…
