Integrable models form pillars of theoretical physics because they allow for full analytical
understanding. Despite being rare, many realistic systems can be described by models that …

We study high-temperature magnetization transport in a many-body spin-1/2 chain with on-
site quasiperiodic potential governed by the Fibonacci rule. In the absence of interactions it …

We investigate the nonequilibrium response of quasiperiodic systems to boundary driving. In
particular, we focus on the Aubry-André-Harper model at its metal-insulator transition and …

We study the finite size scaling of the bulk polarization in a quasiperiodic (Aubry-André)
model using the geometric analog of the Binder cumulant. As a proof of concept, we show …

We show that short-range interactions are irrelevant around gapless ground-state
delocalization-localization transitions driven by quasiperiodicity in interacting fermionic …

Real materials always contain, to some extent, randomness in the form of defects or
irregularities. It is known since the seminal work of Anderson that randomness can drive a …

We develop a scaling theory and a renormalization technique in the context of the modern
theory of polarization. The central idea is to use the characteristic function (also known as …

We study magnetization transport in anisotropic spin-1 2 chains governed by the integrable
XXZ model with and without integrability-breaking perturbations at high temperatures …

We study the interplay between an on-site Hubbard repulsion and quasiperiodic potential in
one-dimensional fermion chains using the density matrix renormalization group. We find …

All undergraduates learn that Bloch theorem and band structure explain the
insulating/metallic behavior of most crystalline solids across the periodic table. By the late …
