Dissipative Dynamics and Symmetry Breaking in Bosonic Sachdev-Ye-Kitaev Lindbladian
Yifei Liu, Anish Kulkarni, Shinsei Ryu
We investigate a bosonic variant of the Sachdev-Ye-Kitaev (SYK) model coupled to a Lindbladian environment, focusing on the interplay between quantum many-body dynamics and dissipa…
Field theory of non-Hermitian disordered systems
Ze Chen, Kohei Kawabata, Anish Kulkarni +1
The interplay between non-Hermiticity and disorder gives rise to unique universality classes of Anderson transitions. Here, we develop a field-theoretical description of non-Hermit…
Non-linear sigma models for non-Hermitian random matrices in symmetry classes AI and AII
Anish Kulkarni, Kohei Kawabata, Shinsei Ryu
Symmetry of non-Hermitian matrices underpins many physical phenomena. In particular, chaotic open quantum systems exhibit universal bulk spectral correlations classified on the bas…
The HMXB Luminosity Functions of Dwarf Galaxies
Robel Geda, Andy D. Goulding, Bret D. Lehmer +2
Drawing from the Chandra archive and using a carefully selected set of nearby dwarf galaxies, we present a calibrated high-mass X-ray binary (HMXB) luminosity function in the low-m…
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…
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…
Lindbladian dynamics of the Sachdev-Ye-Kitaev model
Anish Kulkarni, Tokiro Numasawa, Shinsei Ryu
We study the Lindbladian dynamics of the Sachdev-Ye-Kitaev (SYK) model, where the SYK model is coupled to Markovian reservoirs with jump operators that are either linear or quadrat…
