Pauli component erasing quantum channels
Jose Alfredo de Leon, Alejandro Fonseca, Francois Leyvraz +2
Decoherence of quantum systems is described by quantum channels. However, a complete understanding of such channels, especially in the multi-particle setting, is still an ongoing d…
A trivial observation on time reversal in random matrix theory
L. Kaplan, F. Leyvraz, C. Pineda +1
It is commonly thought that a state-dependent quantity, after being averaged over a classical ensemble of random Hamiltonians, will always become independent of the state. We point…
Large N Scaling Behavior of the Lipkin-Meshkov-Glick Model
F Leyvraz, WD Heiss
We introduce a novel semiclassical approach to the Lipkin model. In this way the well-known phase transition arising at the critical value of the coupling is intuitively understood…
Globally singularity-free semi-classical wave functions in closed form
C. Jung, F. Leyvraz, T. H. Seligman
We use a factorization technique and representation of canonical transformations to construct globally valid closed form expressions without singularities of semi-classical wave fu…
