Eigenstate thermalization in dual-unitary quantum circuits: asymptotics of spectral functions
Felix Fritzsch, Tomaž Prosen
Izvirni znanstveni članek
Oznake: statistična fizika;kvantna mehanika;statistical physics;quantum mechanics;
The eigenstate thermalization hypothesis provides to date the most successful description of thermalization in isolated quantum systems by conjecturing statistical properties of matrix elements of typical operators in the (quasi)energy eigenbasis. Here we study the distribution of matrix elements fo ...

Oznake: kvantna statistična mehanika;kvantni kaos;spinske verige;termalizacija lastnih stanj;teorija naključnih matrik;quantum statistical mechanics;spin chains;eigenstate thermalization;random matrix theory;
Recently, the full version of the eigenstate thermalization hypothesis (ETH) has been systematized using free probability. In this paper, we present a detailed discussion of the free-cumulants approach to many-body dynamics within the microcanonical ensemble. Differences between the latter and canon ...

Full eigenstate thermalization via free cumulants in quantum lattice systems
Silvia Pappalardi, Felix Fritzsch, Tomaž Prosen
Izvirni znanstveni članek

The eigenstate thermalization hypothesis (ETH) has been established as the general framework to understand quantum statistical mechanics. Only recently has the attention been paid to so-called full ETH, which accounts for higher-order correlations among matrix elements, and that can be rationalized ...
