Symmetry of Open Quantum Systems: Classification of Dissipative Quantum Chaos
Kohei Kawabata, Anish Kulkarni, Jiachen Li +2
We develop a theory of symmetry in open quantum systems. Using the operator-state mapping, we characterize symmetry of Liouvillian superoperators for the open quantum dynamics by s…
On SYK traversable wormhole with imperfectly correlated disorders
Tomoki Nosaka, Tokiro Numasawa
In this paper we study the phase structure of two Sachdev-Ye-Kitaev models (L-system and R-system) coupled by a simple interaction, with imperfectly correlated disorder. When the d…
Liouville Theory and the Weil-Petersson Geometry of Moduli Space
Sarah M. Harrison, Alexander Maloney, Tokiro Numasawa
Liouville theory describes the dynamics of surfaces with constant negative curvature and can be used to study the Weil-Petersson geometry of the moduli space of Riemann surfaces. T…
Dynamical quantum phase transitions in SYK Lindbladians
Kohei Kawabata, Anish Kulkarni, Jiachen Li +2
We study the open quantum dynamics of the Sachdev-Ye-Kitaev (SYK) model described by the Lindblad master equation, where the SYK model is coupled to Markovian reservoirs with jump…
Entanglement Phase Transition Induced by the Non-Hermitian Skin Effect
Kohei Kawabata, Tokiro Numasawa, Shinsei Ryu
Recent years have seen remarkable development in open quantum systems effectively described by non-Hermitian Hamiltonians. A unique feature of non-Hermitian topological systems is…
Universal Dynamics of Heavy Operators in Boundary CFT
Tokiro Numasawa, Ioannis Tsiares
We derive a universal asymptotic formula for generic boundary conditions for the average value of the bulk-to-boundary and boundary Operator Product Expansion coefficients of any u…
