Information Compression at Criticality
Simon Jiricek, Miroslav Hopjan, Boris Altshuler +2
Highly excited quantum states at the critical boundary of ergodicity are known to deviate from thermal behavior, yet their dynamical properties remain poorly understood. Here, we u…
Universal Relation between Spectral and Wavefunction Properties at Criticality
Simon Jiricek, Miroslav Hopjan, Vladimir Kravtsov +2
Quantum-chaotic systems exhibit several universal properties, ranging from level repulsion in the energy spectrum to wavefunction delocalization. On the other hand, if wavefunction…
Spectral properties of Levy Rosenzweig-Porter model via supersymmetric approach
Elizaveta Safonova, Mikhail Feigelman, Vladimir Kravtsov
By using the Efetov's super-symmetric formalism we computed analytically the mean spectral density for the Lévy and the Lévy -Rosenzweig-Porter random matrices which off-dia…
