Page curves and typical entanglement in linear optics [PDF]
Quantum, 2023 Bosonic Gaussian states are a special class of quantum states in an infinite dimensional Hilbert space that are relevant to universal continuous-variable quantum computation as well as to near-term quantum sampling tasks such as Gaussian Boson Sampling ...

Entanglement Entropy of Disjoint Regions in Excited States : An Operator Method [PDF]
, 2014 We develop the computational method of entanglement entropy based on the idea that $Tr\rho_{\Omega}^n$ is written as the expectation value of the local operator, where $\rho_{\Omega}$ is a density matrix of the subsystem $\Omega$. We apply it to consider

Quantum Decoherence with Holography [PDF]
, 2014 Quantum decoherence is the loss of a system's purity due to its interaction with the surrounding environment. Via the AdS/CFT correspondence, we study how a system decoheres when its environment is a strongly-coupled theory.

Journal of High Energy Physics, 2021 We study the excited state Rényi entropy and subsystem Schatten distance in the two-dimensional free massless non-compact bosonic field theory, which is a conformal field theory.

Note on entropy dynamics in the Brownian SYK model
Journal of High Energy Physics, 2021 We study the time evolution of Rényi entropy in a system of two coupled Brownian SYK clusters evolving from an initial product state. The Rényi entropy of one cluster grows linearly and then saturates to the coarse grained entropy.

On the average uncertainty for systems with nonlinear coupling [PDF]
, 2016 The increased uncertainty and complexity of nonlinear systems have motivated investigators to consider generalized approaches to defining an entropy function.

Point Information Gain and Multidimensional Data Analysis
, 2016 We generalize the Point information gain (PIG) and derived quantities, i.e. Point information entropy (PIE) and Point information entropy density (PIED), for the case of R\'enyi entropy and simulate the behavior of PIG for typical distributions.

Dynamics of entanglement entropy of interacting fermions in a 1D driven harmonic trap [PDF]
, 2017 Following up on a recent analysis of two cold atoms in a time-dependent harmonic trap in one dimension, we explore the entanglement entropy of two and three fermions in the same situation when driven through a parametric resonance.
