Superfluid to Mott transition in a Bose-Hubbard ring: Persistent currents and defect formation
Lucas Kohn, Pietro Silvi, Matthias Gerster +4
We revisit here the Kibble-Zurek mechanism for superfluid bosons slowly driven across the transition towards the Mott-insulating phase. By means of a combination of the Time-Depend…
Quantum versus classical many-body batteries
Gian Marcello Andolina, Maximilian Keck, Andrea Mari +2
Quantum batteries are quantum mechanical systems with many degrees of freedom which can be used to store energy and that display fast charging. The physics behind fast charging is…
Persistent currents by reservoir engineering
Maximilian Keck, Davide Rossini, Rosario Fazio
We demonstrate that persistent currents can be induced in a quantum system in contact with a structured reservoir, without the need of any applied gauge field. The working principl…
Extractable work, the role of correlations, and asymptotic freedom in quantum batteries
Gian Marcello Andolina, Maximilian Keck, Andrea Mari +3
We investigate a quantum battery made of N two-level systems, which is charged by an optical mode via an energy-conserving interaction. We quantify the fraction E(N) of energy stor…
Entropy production and asymptotic factorization via thermalization: a collisional model approach
Stefano Cusumano, Vasco Cavina, Maximilian Keck +2
The Markovian evolution of an open quantum system is characterized by a positive entropy production, while the global entropy gets redistributed between the system and the environm…
Probabilistic low-rank factorization accelerates tensor network simulations of critical quantum many-body ground states
Lucas Kohn, Ferdinand Tschirsich, Maximilian Keck +3
We provide evidence that randomized low-rank factorization is a powerful tool for the determination of the ground state properties of low-dimensional lattice Hamiltonians through t…
Dissipation in adiabatic quantum computers: Lessons from an exactly solvable model
Maximilian Keck, Simone Montangero, Giuseppe E. Santoro +2
We introduce and study the adiabatic dynamics of free-fermion models subject to a local Lindblad bath and in the presence of a time-dependent Hamiltonian. The merit of these models…
Quantum optimal control within the rotating wave approximation
Maximilian Keck, Matthias M. Müller, Tommaso Calarco +1
We study the interplay between rotating wave approximation and optimal control. In particular, we show that for a wide class of optimal control problems one can choose the control…
