Ultrafast metal-to-insulator switching in a strongly correlated system
Francesco Grandi, Martin Eckstein
Light-manipulation of correlated electronic phases in solids offers the tantalizing prospect of realizing electronic devices operating at the ultrafast time-scale. In this context,…
Fluctuation control of non-thermal orbital order
Francesco Grandi, Martin Eckstein
Orbitally ordered states exhibit unique features which make them a promising platform for exploring the ultrafast dynamics of long-range order in solids: Their free energy typicall…
Ultrafast Mott transition driven by nonlinear electron-phonon interaction
Francesco Grandi, Jiajun Li, Martin Eckstein
Nonlinear phononics holds the promise for controlling properties of quantum materials on the ultrashort timescale. Using nonequilibrium dynamical mean-field theory, we solve a mode…
Unraveling the Mott-Peierls intrigue in Vanadium dioxide
Francesco Grandi, Adriano Amaricci, Michele Fabrizio
Vanadium dioxide is one of the most studied strongly correlated materials. Nonetheless, the intertwining between electronic correlation and lattice effects has precluded a comprehe…
Correlation-driven Lifshitz transition and orbital order in a two-band Hubbard model
Francesco Grandi, Adriano Amaricci, Massimo Capone +1
We study by dynamical mean field theory the ground state of a quarter-filled Hubbard model of two bands with different bandwidths. At half-filling, this model is known to display a…
