Adiabatic Theorem for Quantum Spin Systems
Sven Bachmann, Wojciech De Roeck, Martin Fraas
The first proof of the quantum adiabatic theorem was given as early as 1928. Today, this theorem is increasingly applied in a many-body context, e.g. in quantum annealing and in st…
Indirect acquisition of information in quantum mechanics: states associated with tail events
M. Ballesteros, M. Fraas, J. Fröhlich +1
The problem of reconstructing information on a physical system from data acquired in long sequences of direct (projective) measurements of some simple physical quantities - histori…
On Landau-Zener transitions for dephasing Lindbladians
Martin Fraas, Lisa Hänggli
We consider a driven open system whose evolution is described by a Lindbladian. The Lindbladian is assumed to be dephasing and its Hamiltonian part to be given by the Landau-Zener…
Dynamical crossing of an infinitely degenerate critical point
Sven Bachmann, Martin Fraas, Gian Michele Graf
We study the evolution of a driven harmonic oscillator with a time-dependent frequency . At time the Hamiltonian undergoes a point of infinite spectral degen…
Full statistics of erasure processes: Isothermal adiabatic theory and a statistical Landauer principle
Tristan Benoist, Martin Fraas, Vojkan Jaksic +1
We study driven finite quantum systems in contact with a thermal reservoir in the regime in which the system changes slowly in comparison to the equilibration time. The associated…
