Lyapunov-controlled thermalization: an exact real-time example
Jonas Loy, Jan C. Louw
A verified Kubo-Martin-Schwinger (KMS) relation, after a drive has ceased, is not sufficient evidence to prove equilibrium. We demonstrate this in a large- large- Sachdev-Ye-…
What does "instant thermalization" in large- SYK models mean?
Alexander Osterkorn, Jan C. Louw
Motivated by the Planckian thermalization rate observed in the two-body interacting SYK model, we study thermalization in the -body case. Previous studies of such sy…
Analytical solutions to the non-equilibrium Green's functions in large- SYK models
Jan C. Louw
It is known that the Sachdev-Ye-Kitaev (SYK) model is exactly solvable at leading order in ; specifically, the instantaneously thermal time block after the quench is known in…
Current Correlations and Conductivity in SYK-Like Systems: An Analytical Study
Rishabh Jha, Stefan Kehrein, Jan C. Louw
We present a functional-based approach to compute thermal expectation values for actions expressed in the formalism, applicable to any time sequence ordering. Utilizing this…
Thermodynamics and dynamics of coupled complex SYK models
Jan C. Louw, Linda M. van Manen, Rishabh Jha
It has been known that the large- complex SYK model falls under the same universality class as that of van der Waals (mean-field) and saturates the Maldacena-Shenker-Stanford bo…
Matching partition functions of deformed JT gravity and the cSYK model
Jan C. Louw, Sizheng Cao, Xian-Hui Ge
Motivated by recent analogies between the large- cSYK model and charged black holes, we aim to find a concrete gravitation theory with a matching partition function. Our main fo…
Dynamics and Charge Fluctuations in Large-q Sachdev-Ye-Kitaev Lattices
Rishabh Jha, Jan C. Louw
It is known that the large- complex Sachdev-Ye-Kitaev (SYK) dot thermalizes instantaneously under rather general dynamical protocols. We consider a lattice of such dots coupled…
The shared universality of charged black holes and the many many-body SYK model
Jan Louw, Stefan Kehrein
We investigate the charged -body interacting Sachdev-Ye-Kitaev (SYK) model in the grand-canonical ensemble. By treating as a large parameter, we are able to analytically s…
Thermalization of many many-body interacting SYK models
Jan C. Louw, Stefan Kehrein
We investigate the non-equilibrium dynamics of complex Sachdev-Ye-Kitaev (SYK) models in the limit, where denotes the order of the random Dirac fermion i…
Bosonic representation of a Lipkin-Meshkov-Glick model with Markovian dissipation
Jan C. Louw, Michael Kastner, Johannes N. Kriel
We study the dynamics of a Lipkin-Meshkov-Glick model in the presence of Markovian dissipation, with a focus on late-time dynamics and the approach to thermal equilibrium. Making u…
Thermalization of a Lipkin-Meshkov-Glick model coupled to a bosonic bath
Jan C. Louw, Johannes N. Kriel, Michael Kastner
We derive a Lindblad master equation that approximates the dynamics of a Lipkin-Meshkov-Glick (LMG) model weakly coupled to a bosonic bath. By studying the time evolution of operat…
