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…
Higher spin Richardson-Gaudin model with time-dependent coupling: Exact dynamics
Suvendu Barik, Lieuwe Bakker, Vladimir Gritsev +2
We determine the exact asymptotic many-body wavefunction of a spin- Richardson-Gaudin model with a coupling inversely proportional to time, for time evolution starting from the…
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…
Novel approach of exploring ASEP-like models through the Yang Baxter Equation
Suvendu Barik, Alexander. S. Garkun, Vladimir Gritsev
We explore the algebraic structure of a particular ansatz of Yang Baxter Equation which is inspired from the Bethe Ansatz treatment of the ASEP spin-model. Various classes of Hamil…
Sensitivity of the spectral form factor to short-range level statistics
Wouter Buijsman, Vadim Cheianov, Vladimir Gritsev
The spectral form factor is a dynamical probe for level statistics of quantum systems. The early-time behaviour is commonly interpreted as a characterization of two-point correlati…
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 …
