Fermionization of two-component few-fermion systems in a one-dimensional harmonic trap [PDF]

New Journal of Physics, 2014
The nature of strongly interacting Fermi gases and magnetism is one of the most important and studied topics in condensed-matter physics. Still, there are many open questions.

Magnetic field evolution of white dwarfs in strongly interacting binary star systems [PDF]

, 2009
The surface magnetic field strength of white dwarfs is observed to vary from very little to around 10^9 G. Here we examine the proposal that the strongest fields are generated by dynamo action during the common envelope phase of strongly interacting ...

Polarons and bipolarons in strongly interacting electron-phonon systems [PDF]

Physical Review B, 1995
The Holstein Hubbard and Holstein t--J models are studied for a wide range of phonon frequencies, electron--electron and electron--phonon interaction strengths on finite lattices with up to ten sites by means of direct Lanczos diagonalization. Previously

Strongly interacting confined quantum systems in one dimension [PDF]

Nature Communications, 2014
In one dimension, the study of magnetism dates back to the dawn of quantum mechanics when Bethe solved the famous Heisenberg model that describes quantum behaviour in magnetic systems.

Ground state instability in systems of strongly interacting fermions [PDF]

Journal of Experimental and Theoretical Physics Letters, 1998
We analyze stability of a fermion system with model repulsive pair interaction potential. The possibility for different types of restructuring of the Fermi ground state (at sufficiently great coupling constant) is related to the analytic properties of ...

Exponential bound on information spreading induced by quantum many-body dynamics with long-range interactions

New Journal of Physics, 2016
The dynamics of quantum systems strongly depends on the local structure of the Hamiltonian. For short-range interacting systems, the well-known Lieb–Robinson bound defines the effective light cone with an exponentially small error with respect to the ...

Giant Rectification in Strongly Interacting Driven Tilted Systems

PRX Quantum
Correlated quantum systems feature a wide range of nontrivial effects emerging from interactions between their constituent particles. In nonequilibrium scenarios, these manifest in phenomena such as many-body insulating states and anomalous scaling laws ...

Microlensing of strongly interacting binary systems [PDF]

Astronomy & Astrophysics, 2002
Many binary systems are in a state of strong interaction, where mass exchanges, accretion disks, common envelopes provide circumstellar matter which can have significant effects in microlensing light curves of background sources. Such chromatic absorption effects provide very interesting information on the nature of this diffuse matter and the physics ...

PHSD -- a microscopic transport approach for strongly interacting systems [PDF]

, 2019
We present the basic ideas of the Parton-Hadron-String Dynamics (PHSD) transport approach which is a microscopic covariant dynamical model for strongly interacting systems formulated on the basis of Kadanoff-Baym equations for Green's functions in phase-space representation (in 1st order gradient expansion beyond the quasi-particle approximation).
