Many important processes in science involve the escape of a particle over a barrier. In this
review, we report, extend, and interpret various theories of noise-activated escape. We …

A bstract We study a precise and computationally tractable notion of operator complexity in
holographic quantum theories, including the ensemble dual of Jackiw-Teitelboim gravity and …

The study of molecular dynamics in liquids is an active and exciting area in theoretical,
computational, and experimental chemical physics. The majority of experimental techniques …

We investigate the electronic structure induced by wedge disclinations (conical singularities)
in a honeycomb lattice model realizing Chern numbers γ=±1. We establish a …

We propose a new method for the evaluation of the particle density and kinetic pressure
profiles in inhomogeneous one-dimensional systems of noninteracting fermions, and apply it …

We consider the theory of the resolvent for Hermitian or relaxation operators, and we
address the problem of the explicit evaluation of the Green's function. The continued …

We present a numerically accurate procedure for the study of the electronic structure of one-
dimensional incommensurate systems. Our method is used to infer the localized or extended …

When constructing a Wilson chain to represent a quantum impurity model, the effects of
truncated bath modes are neglected. We show that their influence can be kept track of …

One considers diagonal Padé approximants about∞ of functions of the form f (z)=∫− 1 1 (z−
x)− 1 w (x) dx, z∉[− 1, 1], where w is an integrable, possibly complex-valued, function …

We evaluate the particle current flowing in steady state through a Bose–Einstein condensate
subject to a constant force in a quasi-one-dimensional lattice and to attractive interactions …
