Fragility of superposition states evaluated by the Loschmidt Echo
Denise Bendersky, Pablo R. Zangara, Horacio M. Pastawski
We consider the degradation of the dynamics of a Gaussian wave packet in a harmonic oscillator under the presence of an environment. This last is given by a single non-degenerate t…
Time Fluctuations in Isolated Quantum Systems of Interacting Particles
Pablo R. Zangara, Axel D. Dente, E. J. Torres-Herrera +3
Numerically, we study the time fluctuations of few-body observables after relaxation in isolated dynamical quantum systems of interacting particles. Our results suggest that they d…
Interaction-disorder competition in a spin system evaluated through the Loschmidt Echo
Pablo R. Zangara, Axel D. Dente, Aníbal Iucci +2
The interplay between interactions and disorder in closed quantum many-body systems is relevant for thermalization phenomenon. In this article, we address this competition in an in…
GPU accelerated Trotter-Suzuki solver for quantum spin dynamics
Axel D. Dente, Carlos S. Bederián, Pablo R. Zangara +1
The resolution of dynamics in out of equilibrium quantum spin systems lies at the heart of fundamental questions among Quantum Information Processing, Statistical Mechanics and Nan…
