Matter Coupling of Dirac Matter in the Context of the SYK Model: Non-Gaussian Random Couplings and Bulk Mass Deformations
Pak Hang Chris Lau, Chen-Te Ma, Jeff Murugan +1
We elaborate further on the matter coupling of Dirac matter in the SYK framework, incorporating non-Gaussian coupling distributions and bulk fermion mass effects. Our study analyze…
Gravitational EFT for dissipative open systems
Pak Hang Chris Lau, Kanji Nishii, Toshifumi Noumi
We elaborate on the effective field theory (EFT) construction for dissipative open systems coupled to dynamical gravity, in light of recent developments on the EFT of dissipative h…
Detecting quantum chaos via pseudo-entropy
Song He, Pak Hang Chris Lau, Long Zhao
Quantum informatic quantities such as entanglement entropy are useful in detecting quantum phase transitions. Recently, a new entanglement measure called pseudo-entropy was propose…
On the Backreaction of Dirac Matter in JT Gravity and SYK Model
Pak Hang Chris Lau, Chen-Te Ma, Jeff Murugan +1
We model backreaction in AdS JT gravity via a proposed boundary dual Sachdev-Ye-Kitaev quantum dot coupled to Dirac fermion matter and study it from the perspective of quantum…
Randomness and Chaos in Qubit Models
Pak Hang Chris Lau, Chen-Te Ma, Jeff Murugan +1
We introduce randomness into a class of integrable models and study the spectral form factor as a diagnostic to distinguish between randomness and chaos. Spectral form factors exhi…
