Exact spectral form factors of noninteracting fermions with Dyson statistics
Tatsuhiko N. Ikeda, Lev Vidmar, Michael O. Flynn
Izvirni znanstveni članek
Oznake: kvantni kaos;neurejeni sistemi;physics;quantum chaos;disordered systems;localization;critical point;
The spectral form factor (SFF) is a powerful diagnostic of random matrix behavior in quantum many-body systems. We introduce a family of random circuit ensembles whose SFFs can be computed exactly. These ensembles describe the evolution of noninteracting fermions in the presence of correlated on-sit ...

Oznake: kvantni kaos;neurejeni sistemi;physics;quantum chaos;disordered systems;
We consider systems of fermions evolved by noninteracting unitary circuits with correlated on-site potentials. When these potentials are drawn from the eigenvalue distribution of a circular random matrix ensemble, the single-particle sector exhibits chaotic dynamics. The corresponding many-body spec ...

Oznake:
When the mitochondrial network within the cell is in a fragmented state, it resembles a spatial distribution of prolate spheroids of various shapes, sizesand orientations. This paper presents a maximum-likelihood scheme for inferring the distribution of spheroidal shapes, sizes and orientations from ...

Integrating motivational signals with cognition is critical for goal-directed activities. The mechanisms that link neural changes with motivated working memory continue to be understood. Here, we tested how externally cued and non-cued (internally represented) reward and loss impact spatial working ...
