We investigate the time-dependent reformation of the quasiparticle peak in a correlated metal near the Mott transition, after the system is quenched into a hot electron state and equilibrates with an environment which is colder than the Fermi-liquid crossover temperature. Close to the transition, we identify a purely electronic bottleneck time scale, which depends on the spectral weight around the Fermi energy in the bad metallic phase in a nonlinear way. This time scale can be orders of…

Momentum-dependent relaxation dynamics of the doped repulsive Hubbard model
We study the dynamical behavior of doped electronic systems subject to a global ramp of the repulsive Hubbard interaction. We start with formulating a real-time generalization of the
Timescale of local moment screening across and above the Mott transition
A material’s phase diagram typically indicates the types of realized long-range orders, corresponding to instabilities in static response functions. In correlated systems, however, key phenomena
Comparative study of nonequilibrium insulator-to-metal transitions in electron-phonon systems
We study equilibrium and nonequilibrium properties of electron-phonon systems described by the Hubbard-Holstein model using dynamical mean-field theory. In equilibrium, we benchmark the results for
Entropic Origin of Pseudogap Physics and a Mott-Slater Transition in Cuprates
An order-parameter classification scheme that predicts supertransitions between families of order parameters is developed and it is found that by tuning the hopping parameters, it is possible to drive the cuprates across a transition between Mott and Slater physics, where a spin-frustrated state emerges at the crossover.
Entropy-cooled nonequilibrium states of the Hubbard model
We show that the recently proposed cooling-by-doping mechanism allows to efficiently prepare interesting nonequilibrium states of the Hubbard model. Using nonequilibrium dynamical mean field theory
Dynamic control of nonequilibrium metal-insulator transitions
We demonstrate a first order metal-insulator phase transition in the repulsive, fully frustrated, single-band Hubbard model as a function of the coupling to a fermion bath. Time dependent
From the Keldysh Formalism to Non-equilibrium Dynamical Mean-Field Theory
Using femto-second laser-pulses one can investigate correlated electrons in solids far from equilibrium, and possibly even manipulate their behavior in a controlled and ultrafast manner. The
Tracking the insulator-to-metal phase transition in VO2 with few-femtosecond extreme UV transient absorption spectroscopy
A record speed is measured for the phase transition of 26 fs into a long-lived excited state of the metal that persists out to >60 ps and the measured femtosecond timescale provides fundamental insight into the electronic speed limits of these complex phenomena.

Nonequilibrium electron-lattice dynamics
Die Optimierung verschiedener Materialeigenschaften ist seit Jahrzehnten ein Ziel der Festkorperphysik. In den letzten Jahren hat die Entwicklung von ultraschnellen Techniken neue Moglichkeiten
