Electron-Phonon Interaction in Strongly Correlated Systems [PDF]
The Hubbard-Holstein model is a simple model including both electron-phonon interaction and electron-electron correlations. We review a body of theoretical work investigating, the effects of strong correlations on the electron-phonon interaction. We focus on the regime, relevant to high-Tcsuperconductors, in which the electron correlations are dominant.

Dilepton radiation from strongly interacting systems
We review the current understanding of time-like virtual photon emission from QCD matter. The phenomenology of dilepton emission is discussed and basic theoretical concepts are introduced. The experimental findings are presented, grouped into production of lepton pairs in elementary processes, production off cold nuclear matter and emission from heavy ...

Strongly Interacting Few-Fermion Systems in a Trap [PDF]
Few- and many-fermion systems on the verge of stability, and consisting of strongly interacting particles, appear in many areas of physics. The theoretical modeling of such systems is a very difficult problem. In this work we present a theoretical framework that is based on the rigged Hilbert space formulation.

Robust Quantum Sensing in Strongly Interacting Systems with Many-Body Scars
In most quantum sensing schemes, interactions between the constituent particles of the sensor are expected to lead to thermalization and degraded sensitivity. However, recent theoretical and experimental work has shown that the phenomenon of quantum many-

Quantum Metrology with Strongly Interacting Spin Systems
Quantum metrology is a powerful tool for explorations of fundamental physical phenomena and applications in material science and biochemical analysis. While in principle the sensitivity can be improved by increasing the density of sensing particles, in ...

Polariton dynamics in strongly interacting quantum many-body systems
We develop a theory for light propagating in an atomic Bose-Einstein condensate in the presence of strong interactions. The resulting many-body correlations are shown to have profound effects on the optical properties of this interacting medium. For weak

Apparent Electron-Phonon Interaction in Strongly Correlated Systems [PDF]
We study the interaction of electrons with phonons in strongly correlated solids, having high-T_c cuprates in mind. Using sum-rules, we show that the apparent strength of this interaction strongly depends on the property studied. If the solid has a small fraction (doping) delta of charge carriers, the influence of the interaction on the phonon self ...

Strongly interacting mesoscopic systems of anyons in one dimension [PDF]
Using the fractional statistical properties of so-called anyonic particles, we present exact solutions for up to six strongly interacting particles in one-dimensional confinement that interpolate the usual bosonic and fermionic limits.

Nonlocal exchange interactions in strongly correlated electron systems [PDF]
We study the influence of ferromagnetic nonlocal exchange on correlated electrons in terms of a $SU(2)$-Hubbard-Heisenberg model and address the interplay of on-site interaction induced local moment formation and the competition of ferromagnetic direct and antiferromagnetic kinetic exchange interactions. In order to simulate thermodynamic properties of

Fermionic Properties of Two Interacting Bosons in a Two-Dimensional Harmonic Trap
The system of two interacting bosons in a two-dimensional harmonic trap is compared with the system consisting of two noninteracting fermions in the same potential. In particular, we discuss how the properties of the ground state of the system, e.g., the
