Dissipation in the expansion for planar matrix models
Takanori Anegawa, Norihiro Iizuka, Daniel Kabat
We consider the thermal behavior of a large number of matrix degrees of freedom in the planar limit. We work in dimensions, with matrices, and use as an expansion p…
Krylov complexity of fermion chain in double-scaled SYK and power spectrum perspective
Takanori Anegawa, Ryota Watanabe
We investigate Krylov complexity of the fermion chain operator which consists of multiple Majorana fermions in the double-scaled SYK (DSSYK) model with finite temperature. Using th…
Black Hole Singularity and Timelike Entanglement
Takanori Anegawa, Kotaro Tamaoka
We study timelike and conventional entanglement entropy as potential probes of black hole singularities via the AdS/CFT correspondence. Using an analytically tractable example, we…
Krylov complexity as an order parameter for deconfinement phase transitions at large
Takanori Anegawa, Norihiro Iizuka, Mitsuhiro Nishida
Krylov complexity has been proposed as a diagnostic of chaos in non-integrable lattice and quantum mechanical systems, and if the system is chaotic, Krylov complexity grows exponen…
