Entanglement Dynamics by (Non-)Unitary Local Operator Quenches in a 2D Holographic CFT

Weibo Mao, Akihiro Miyata, Masahiro Nozaki +1

In this paper, we investigate the time evolution of entanglement entropy and mutual information for the spatially-infinite systems where we act with a primary operator on the vacuu…

Relaxation Process During Complex Time Evolution In Two-Dimensional Integrable and Chaotic CFTs

Chen Bai, Weibo Mao, Masahiro Nozaki +2

We investigate the complex time evolution of a vacuum state with the insertion of a local primary operator in two-dimensional conformal field theories (2d CFTs). This complex time…

Quantum Chaos, Thermalization, and Non-locality

Masataka Matsumoto, Shuta Nakajima, Masahiro Nozaki +1

In this paper, we numerically investigate whether quantum thermalization occurs during the time evolution induced by a non-local Hamiltonian whose spectra exhibit integrability. Th…

Time Ordering Effects and Destruction of Quasiparticles in Two-dimensional Holographic CFTs

Weibo Mao, Masahiro Nozaki

In this paper, we investigate the entanglement dynamics induced by a composite operator, defined as the local operator evolved with the time evolution operator constructed of the E…

Entanglement dynamics in 2d HCFTs on the curved background: the case of q-Möbius Hamiltonian

Chen Bai, Akihiro Miyata, Masahiro Nozaki

We will explore the dynamical property of non-equilibrium phenomena induced by two-dimensional holographic conformal field theory (2d holographic CFT) Hamiltonian on the curved spa…

Hawking-Page and entanglement phase transition in 2d CFT on curved backgrounds

Akihiro Miyata, Masahiro Nozaki, Kotaro Tamaoka +1

The thermodynamics and the entanglement properties of two-dimensional conformal field theories (d CFTs) on curved backgrounds are studied. By means of conformal mapping we study…
