Kondo Echo Dynamics of Terahertz-Pumped Heavy Fermions
Francisco Meirinhos, Michael Turaev, Michael Kajan +2
We provide a theoretical framework to describe the nonequilibrium temporal dynamics of correlated electron systems for realistic system parameters and the consequent, often exponen…
Kondo singlet from ferromagnetic coupling: an analog of Anderson-Morel superconductivity in the magnetic channel
Ewan Scott, Yaqi Chen, Michael Turaev +4
We consider magnetic impurities coupled to a conduction sea via a fully isotropic ferromagnetic spin-exchange term, the strength of which depends on the conduction-electron modes i…
Emergent thermal fluctuations and non-Hermitian phase transitions in open photon condensates
Moritz Janning, Roman Kramer, Michael Turaev +2
We investigate the nonequilibrium dynamics of an open photon Bose-Einstein condensate in a dye-filled microcavity using a Lindblad master-equation approach, treating the condensate…
Expansion dynamics of strongly correlated lattice bosons: A selfconsistent density-matrix approach
Julian Schwingel, Michael Turaev, Johann Kroha +1
We study the spatio-temporal dynamics of interacting bosons on a two-dimensional Hubbard lattice in the strongly interacting regime, taking into account the dynamics of condensate…
Stabilizing open photon condensates by ghost-attractor dynamics
Aya Abouelela, Michael Turaev, Roman Kramer +4
We study the temporal, driven-dissipative dynamics of open photon Bose-Einstein condensates (BEC) in a dye-filled microcavity, taking the condensate amplitude and the noncondensed…
Discovery of a non-Hermitian phase transition in a bulk condensed-matter system
Jingwen Li, Michael Turaev, Masakazu Matsubara +5
Phase transitions are fundamental in nature. A small parameter change near a critical point leads to a qualitative change in system properties. Across a regular phase transition, t…
