On optimal currents of indistinguishable particles
Mattia Walschaers, Andreas Buchleitner, Mark Fannes
We establish a mathematically rigorous, general and quantitative framework to describe currents of non- (or weakly) interacting, indistinguishable particles driven far from equilib…
Monotonicity of the von Neumann entropy expressed as a function of Rényi entropies
Mark Fannes
The von Neumann entropy of a density matrix of dimension d, expressed in terms of the first d-1 integer order Rényi entropies, is monotonically increasing in Rényi entropies of eve…
Extractable work from ensembles of quantum batteries. Entanglement helps
Robert Alicki, Mark Fannes
Motivated by the recent interest in thermodynamics of micro- and mesoscopic quantum systems we study the maximal amount of work that can be reversibly extracted from a quantum syst…
Connecting the von Neumann and Renyi entropies for Fermions
Mark Fannes, Nicholas Van Ryn
We explore the relation between the von Neumann entropy and the Renyi entropies of integer orders for shift-invariant quasi-free Fermionic lattice systems. We investigate approxima…
Fermionic Markov Chains
Mark Fannes, Jeroen Wouters
We study a quantum process that can be considered as a quantum analogue for the classical Markov process. We specifically construct a version of these processes for free Fermions.…
Matrices of fidelities for ensembles of quantum states and the Holevo quantity
Mark Fannes, Fernando de Melo, Wojciech Roga +1
The entropy of the Gram matrix of a joint purification of an ensemble of K mixed states yields an upper bound for the Holevo information Chi of the ensemble. In this work we combin…
