The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

The study of critical properties of systems with long-range interactions has attracted, in
recent decades, a continuing interest and motivated the development of several analytical …

Several recent experiments in atomic, molecular, and optical systems motivated a huge
interest in the study of quantum long-range systems. Our goal in this paper is to present a …

How do isolated quantum systems approach an equilibrium state? We experimentally and
theoretically address this question for a prototypical spin system formed by ultracold atoms …

We present an exact analytical solution for quantum strong long-range models in the
canonical ensemble by extending the classical solution proposed in Campa et al.[J. Phys. A …

We employ a neural-network architecture based on the vision transformer (ViT) architecture
to find the ground states of quantum long-range models, specifically the transverse-field …

We consider anisotropic long-range interacting spin systems in d dimensions. The
interaction between the spins decays with the distance as a power law with different …

We consider the transverse field Ising model with additional all-to-all interactions between
the spins. We show that a mean-field treatment of this model becomes exact in the …

Enhanced experimental capabilities to control nonlocal and power-law decaying
interactions are currently fueling intense research in the domain of quantum many-body …

Simple elastic models of spin-crossover compounds are known empirically to exhibit
classical critical behavior. We demonstrate how the long-range interactions responsible for …
