Efficient nonequilibrium electron dynamics from first-principles: leveraging Koopmans spectral functionals and Wannier localization
Giovanni Cistaro, Miguel Sá, Davide Sangalli +2
We present an efficient first-principles approach for simulating the nonequilibrium electron dynamics in extended systems beyond the linear regime. The method combines Koopmans-com…
Excitonic optical absorption in strained monolayer CrSBr
Maurício F. C. Martins Quintela, Guilherme J. Inacio, Miguel Sá +5
Recently, the isolation of 2D magnetic materials has opened several avenues for possible new ap- plications in spintronics. Among these materials, CrSBr has sparked interest due to…
Semiconductor Wannier equations: a real-time, real-space approach to the nonlinear optical response in crystals (ATATA)
Eduardo B. Molinero, Bruno Amorim, Misha Ivanov +6
We develop the semiconductor Wannier equations (SWEs), a real-time, real-space formulation of ultrafast light-matter dynamics in crystals, by deriving the equations of motion for t…
Quantum valley pseudospin controlled by strain
Maurício F. C. Martins Quintela, Miguel Sá, Alejandro J. Uría-Álvarez +5
Valleytronics, as an alternative to traditional electronics or spintronics, is based on the encoding of quantum information in pseudospin valley quantum numbers, rather than in cha…
Topological phase transitions via attosecond x-ray absorption spectroscopy
Juan F. P. Mosquera, Giovanni Cistaro, Mikhail Malakhov +6
We present a numerical experiment that demonstrates the possibility to capture topological phase transitions via an x-ray absorption spectroscopy scheme. We consider a Chern insula…
Exciton migration in two-dimensional materials
Mikhail Malakhov, Giovanni Cistaro, Fernando Martín +1
Excitons play an essential role in the optical response of two-dimensional materials. These are bound states showing up in the band gaps of many-body systems and are conceived as q…
Formation, stability, and highly nonlinear optical response of excitons to intense light fields interacting with two-dimensional materials
Eduardo B. Molinero, Bruno Amorim, Mikhail Malakhov +6
Excitons play a key role in the linear optical response of 2D materials. However, their significance in the highly nonlinear optical response to intense mid-infrared light has ofte…
A theoretical approach for electron dynamics and ultrafast spectroscopy
Giovanni Cistaro, Mikhail Malakhov, Juan José Esteve-Paredes +5
In this manuscript we present a theoretical framework and its numerical implementation to simulate the out-of-equilibrium electron dynamics induced by the interaction of ultrashort…
