Quantum vs. classical information: operator negativity as a probe of scrambling
Jonah Kudler-Flam, Masahiro Nozaki, Shinsei Ryu +1
We consider the logarithmic negativity and related quantities of time evolution operators. We study free fermion, compact boson, and holographic conformal field theories (CFTs) as…
Entanglement after Quantum Quenches in Lifshitz Scalar Theories
Keun-Young Kim, Mitsuhiro Nishida, Masahiro Nozaki +3
We study the time evolution of the entanglement entropy after quantum quenches in Lifshitz free scalar theories, with the dynamical exponent , by using the correlator method.…
Dynamics of logarithmic negativity and mutual information in smooth quenches
Hiroyuki Fujita, Mitsuhiro Nishida, Masahiro Nozaki +1
In this paper, we study how quantum correlation between subsystems changes in time by investigating time evolution of mutual information and logarithmic negativity in two protocols…
Holographic Duals of Inhomogeneous Systems: The Rainbow Chain and the Sine-Square Deformation Model
Ian MacCormack, Aike Liu, Masahiro Nozaki +1
A holographic dual description of inhomogeneous systems is discussed. Notably, finite temperature results for the entanglement entropy in both the rainbow chain and the SSD model a…
Signature of quantum chaos in operator entanglement in 2d CFTs
Laimei Nie, Masahiro Nozaki, Shinsei Ryu +1
We study operator entanglement measures of the unitary evolution operators of (1+1)-dimensional conformal field theories (CFTs), aiming to uncover their scrambling and chaotic beha…
Entanglement Spreading and Oscillation
Mitsuhiro Nishida, Masahiro Nozaki, Yuji Sugimoto +1
We study dynamics of quantum entanglement in smooth global quenches with a finite rate, by computing the time evolution of entanglement entropy in 1 + 1 dimensional free scalar the…
