The Dynamic Reorganization of Cortical Network Interactions during Visual Selective Attention

Pagnotta, Mattia ; Plomp, Gijs (Dir.)

Thèse de doctorat : Université de Fribourg, 2020.

Visual selective attention prioritizes the processing of behaviorally relevant over irrelevant information, to optimize the use of limited cognitive resources in the brain. These selective mechanisms preferentially route relevant neuronal representations through a network of distributed brain regions. Previous studies suggested that selective information routing in the attention network may...

Quantum Boltzmann equation for strongly correlated systems: Comparison to dynamical mean field theory

Wais, Michael ; Eckstein, Martin ; Fischer, R. ; Werner, Philipp ; Battiato, M. ; Held, K.

We investigate the potential of a quantum Boltzmann equation without momentum conservation for description of strongly correlated electron systems out of equilibrium. In a spirit similar to dynamical mean field theory (DMFT), the momentum conservation of the electron-electron scattering is neglected, which yields a time-dependent occupation function for the equilibrium spectral function, even...
