Chaos by Magic
Kanato Goto, Tomoki Nosaka, Masahiro Nozaki
There is a property of a quantum state called magic. It measures how difficult for a classical computer to simulate the state. In this paper, we study magic of states in the integr…
Non-Equilibrating a Black Hole with Inhomogeneous Quantum Quench
Kanato Goto, Masahiro Nozaki, Shinsei Ryu +2
We study quantum quench processes in (1+1)-dimensional conformal field theory (CFT) in which the initial thermal equilibrium (Gibbs) state is time-evolved by spatially inhomogeneou…
Information Scrambling Versus Quantum Revival Through the Lens of Operator Entanglement
Kanato Goto, Ali Mollabashi, Masahiro Nozaki +2
In this paper, we look for signatures of quantum revivals in two-dimensional conformal field theories (2d CFTs) on a spatially compact manifold by using operator entanglement. It i…
Subregion Spectrum Form Factor via Pseudo Entropy
Kanato Goto, Masahiro Nozaki, Kotaro Tamaoka
We introduce a subsystem generalization of the spectral form factor via pseudo entropy, the von-Neumann entropy for the reduced transition matrix. We consider a transition matrix b…
