Turning Down the Noise: Power-Law Decay and Temporal Phase Transitions
Lieuwe Bakker, Suvendu Barik, Vladimir Gritsev +1
We determine the late-time dynamics of a generic spin ensemble with inhomogeneous broadening - equivalently, qubits with arbitrary Zeeman splittings - coupled to a dissipative envi…

Knizhnik-Zamolodchikov equations and integrable hyperbolic Landau-Zener models
Suvendu Barik, Lieuwe Bakker, Vladimir Gritsev +1
We study the relationship between integrable Landau-Zener (LZ) models and Knizhnik-Zamolodchikov (KZ) equations. The latter are originally equations for the correlation functions o…

Random Matrix Ensemble for the Level Statistics of Many-Body Localization
Wouter Buijsman, Vadim Cheianov, Vladimir Gritsev
We numerically study the level statistics of the Gaussian ensemble. These statistics generalize Wigner-Dyson level statistics from the discrete set of Dyson indices …
