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…
