Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

A bstract Inspired by the universal operator growth hypothesis, we extend the formalism of
Krylov construction in dissipative open quantum systems connected to a Markovian bath …

The scrambling of quantum information in closed many-body systems, as measured by out-
of-time-ordered correlation functions (OTOCs), has received considerable attention lately …

A bstract Continuing the previous initiatives [1, 2], we pursue the exploration of operator
growth and Krylov complexity in dissipative open quantum systems. In this paper, we resort …

A bstract Using spread complexity and spread entropy, we study non-unitary quantum
dynamics. For non-hermitian Hamiltonians, we extend the bi-Lanczos construction for the …

The effort to discover a quantum theory of gravity is motivated by the need to reconcile the
incompatibility between quantum theory and general relativity. Here, we present an …

We present a summary of recent progress and remaining challenges in applying the
methods and ideas of quantum information theory to the study of quantum field theory and …

A bstract We initiate the study of open quantum field theories using holographic methods.
Specifically, we consider a quantum field theory (the system) coupled to a holographic field …

In modern cosmology, scalar fields with screening mechanisms are often used as
explanations for phenomena like dark energy or dark matter. Amongst a zoo of models, the …

We revisit the problem involving two constantly accelerating Unruh-DeWitt detectors using
open effective field theory methods. We study the time evolution of the joint detector state …
