Orthogonality Catastrophe as a Consequence of the Quantum Speed Limit
Thomás Fogarty, Sebastian Deffner, Thomas Busch +1
A remarkable feature of quantum many-body systems is the orthogonality catastrophe which describes their extensively growing sensitivity to local perturbations and plays an importa…
Thermalization of finite many-body systems by a collision model
Onat Arısoy, Steve Campbell, Özgür E. Müstecaplıoğlu
We construct a collision model description of the thermalization of a finite many-body system by using careful derivation of the corresponding Lindblad-type master equation in the…
Spin-orbit coupling in the presence of strong atomic correlations
Ayaka Usui, Thomás Fogarty, Steve Campbell +2
We explore the influence of contact interactions on a synthetically spin-orbit coupled system of two ultracold trapped atoms. Even though the system we consider is bosonic, we show…
Quantum Thermodynamics: An introduction to the thermodynamics of quantum information
Sebastian Deffner, Steve Campbell
This book provides an introduction to the emerging field of quantum thermodynamics, with particular focus on its relation to quantum information and its implications for quantum co…
Energetic cost of quantum control protocols
Obinna Abah, Ricardo Puebla, Anthony Kiely +3
We quantitatively assess the energetic cost of several well-known control protocols that achieve a finite time adiabatic dynamics, namely counterdiabatic and local counterdiabatic…
Stable adiabatic quantum batteries
Alan C. Santos, Barış Çakmak, Steve Campbell +1
With the advent of quantum technologies comes the requirement of building quantum components able to store energy to be used whenever necessary, i.e. quantum batteries. In this pap…
Precursors of non-Markovianity
Steve Campbell, Maria Popovic, Dario Tamascelli +1
Using the paradigm of information backflow to characterize a non-Markovian evolution, we introduce so-called precursors of non-Markovianity, i.e. necessary properties that the syst…
Discrete and generalized phase space techniques in critical quantum spin chains
Zakaria Mzaouali, Steve Campbell, Morad El Baz
We apply the Wigner function formalism from quantum optics via two approaches, Wootters' discrete Wigner function and the generalized Wigner function, to detect quantum phase trans…
Collisional unfolding of quantum Darwinism
Steve Campbell, Barış Çakmak, Özgür E. Müstecaplıoğlu +2
We examine the emergence of objectivity via quantum Darwinism through the use of a collision model, i.e. where the dynamics is modeled through sequences of unitary interactions bet…
