Role of energy uncertainties in ergodicity breaking induced by competing interactions and disorder. A dynamical assessment through the Loschmidt echo
Pablo R. Zangara, Patricia R. Levstein, Horacio M. Pastawski
A local excitation in a quantum many-particle system evolves deterministically. A time-reversal procedure, involving the invertion of the signs of every energy and interaction, sho…
Loschmidt echo in many-spin systems: contrasting time-scales of local and global measurements
Pablo R. Zangara, Denise Bendersky, Patricia R. Levstein +1
A local excitation in a quantum many-spin system evolves deterministically. A time-reversal procedure, involving the inversion of the signs of every energy and interaction, should…
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…
The Loschmidt Echo as a robust decoherence quantifier for many-body systems
Pablo R. Zangara, Axel D. Dente, Patricia R. Levstein +1
We employ the Loschmidt Echo, i.e. the signal recovered after the reversal of an evolution, to identify and quantify the processes contributing to decoherence. This procedure, whic…
Storage of Quantum Coherences as Phase Labeled Local Polarization in Solid State NMR
María Belén Franzoni, Rodolfo H. Acosta, Horacio M. Pastawski +1
Nuclear spins are promising candidates for quantum information processing because their good isolation from the environment precludes the rapid loss of quantum coherence. Many stra…
Perfect state transfers by selective quantum interferences within complex spin networks
Gonzalo A. Alvarez, Mor Mishkovsky, Ernesto P. Danieli +3
We present a method that implement directional, perfect state transfers within a branched spin network by exploiting quantum interferences in the time-domain. That provides a tool…
