Non-equilibrium magnetic interactions in strongly correlated systems [PDF]

open access: yesAnnals of Physics, 2013
We formulate a low-energy theory for the magnetic interactions between electrons in the multi-band Hubbard model under non-equilibrium conditions determined by an external time-dependent electric field which simulates laser-induced spin dynamics. We derive expressions for dynamical exchange parameters in terms of non-equilibrium electronic Green ...

Quantum synchronisation enabled by dynamical symmetries and dissipation

open access: yesNew Journal of Physics, 2020
In nature, instances of synchronisation abound across a diverse range of environments. In the quantum regime, however, synchronisation is typically observed by identifying an appropriate parameter regime in a specific system.

Topological invariant and cotranslational symmetry in strongly interacting multi-magnon systems

open access: yesNew Journal of Physics, 2018
It is still an outstanding challenge to characterize and understand the topological features of strongly interacting states such as bound states in interacting quantum systems.

Itinerant ferromagnetism in SU(N)-symmetric fermi gases at finite temperature: first order phase transitions and time-reversal symmetry

open access: yesNew Journal of Physics, 2023
At temperatures well below the Fermi temperature T _F , the coupling of magnetic fluctuations to particle-hole excitations in a two-component Fermi gas leads to non-analytic corrections in the renormalized free energy and makes the transition to ...

New Reentrant Insulating Phases in Strongly Interacting 2D Systems with Low Disorder

open access: yesApplied Sciences, 2018
The metal-insulator transition (MIT) in two-dimension (2D) was discovered by Kravchenko et al. more than two decades ago in strongly interacting 2D electrons residing in a Si-metal-oxide-semiconductor field-effect transistor (Si-MOSFET).

Nonuniversality and strongly interacting two-level systems in glasses at low temperatures

open access: yesNew Journal of Physics, 2018
Recent experimental results showing atypical nonlinear absorption and marked deviations from well known universality in the low temperature acoustic and dielectric losses in amorphous solids prove the need for improving the understanding of the nature of

Green functions of interacting systems in the strongly localized regime [PDF]

open access: yesJournal of Physics: Condensed Matter, 2015
We have developed an approach to calculate the single-particle Green function of a one-dimensional many-body system in the strongly localized limit at zero temperature. Our approach, based on the locator expansion, sums the contributions of all possible forward scattering paths in configuration space. We demonstrate for fermions that the Green function

Covariant transport approach for strongly interacting partonic systems

open access: yes, 2010
The dynamics of partons, hadrons and strings in relativistic nucleus-nucleus collisions is analyzed within the novel Parton-Hadron-String Dynamics (PHSD) transport approach, which is based on a dynamical quasiparticle model for partons (DQPM) matched to ...

Theoretical Perspectives on Viscous Nature of Strongly Interacting Systems

open access: yesUniverse
Matter prevailing during the early stages of the Universe or under extreme conditions in high-energy heavy-ion experiments supposedly possesses a rich phase structure.
