Ultrafast dynamics in relativistic Mott insulators
Jiajun Li, Nagamalleswararao Dasari, Martin Eckstein
We study the photoinduced ultrafast dynamics in relativistic Mott insulators, i.e., Mott insulators with strong spin-orbit coupling. For this purpose, we consider a minimal one-ban…
A photo-induced strange metal with electron and hole quasi-particles
Nagamalleswararao Dasari, Jiajun Li, Philipp Werner +1
Photo-doping of Mott insulators or correlated metals can create an unusual metallic state which simultaneously hosts hole-like and electron-like particles. We study the dynamics of…
Revealing Hund's multiplets in Mott insulators under strong electric fields
Nagamalleswararao Dasari, Jiajun Li, Philipp Werner +1
We investigate the strong-field dynamics of a paramagnetic two-band Mott insulator using real-time dynamical mean-field theory. A dielectric breakdown occurs due to many-body Landa…
Ultra-fast electric field controlled spin-fluctuations in the Hubbard model
Nagamalleswararao Dasari, Martin Eckstein
Highly intense electric field pulses can move the electronic momentum occupation in correlated metals over large portions of the Brillouin zone, leading to phenomena such as dynami…
Transient Floquet engineering of superconductivity
Nagamalleswararao Dasari, Martin Eckstein
Intense time-periodic laser fields can transform the electronic structure of a solid into strongly modified Floquet-Bloch bands. While this suggests multiple pathways to induce ele…
Emergent Strange Nodal Metallicity from Orbital-Selective Mott Physics
Swagata Acharya, Mukul S. Laad, Nagamalleswararao Dasari +3
While a specific kind of strange metal is increasingly found to be the "normal" states in a wide variety of unconventional superconductors, its microscopic origin is presently a ho…
