Light-Driven Extremely Nonlinear Bulk Photogalvanic Currents
(American Physical Society, 2021-09-13)
We predict the generation of bulk photocurrents in materials driven by bichromatic fields that arc circularly polarized and corotating. The nonlinear photocurrents have a fully controllable directionality and amplitude ...
TMDs as a platform for spin liquid physics: A strong coupling study of twisted bilayer WSe2
(American Institute of Physics, 2022)
[EN] The advent of twisted moire heterostructures as a playground for strongly correlated electron physics has led to a plethora of experimental and theoretical efforts seeking to unravel the nature of the emergent ...
Engineering Three-Dimensional Moire Flat Bands
(American Chemical Society, 2021-09-22)
Twisting two adjacent layers of van der Waals materials with respect to each other can lead to flat two-dimensional electronic bands which enables a wealth of physical phenomena. Here, we generalize this concept of so-called ...
Moireless Correlations in ABCA Graphene
(National Academy of Sciences, 2021-01-26)
Atomically thin van der Waals materials stacked with an interlayer twist have proven to be an excellent platform toward achieving gate-tunable correlated phenomena linked to the formation of flat electronic bands. In this ...
Excited-state band structure mapping
(American Physical Society, 2022-02-15)
[EN] Angle-resolved photoelectron spectroscopy is an extremely powerful probe of materials to access the occupied electronic structure with energy and momentum resolution. However, it remains blind to those dynamic states ...
Nanometer-Scale Lateral p–n Junctions in Graphene/α-RuCl3 Heterostructures
(American Chemical Society, 2022)
[EN] The ability to create nanometer-scale lateral p-n junctions is essential for the next generation of two-dimensional (2D) devices. Using the charge-transfer heterostructure graphene/alpha-RuCl3, we realize nanoscale ...
Probing phonon dynamics with multidimensional high harmonic carrier-envelope-phase spectroscopy
(National Academy of Sciences, 2022-06)
We explore pump-probe high harmonic generation (HHG) from monolayer hexagonalboron-nitride, where a terahertz pump excites coherent optical phonons that are subsequently probed by an intense infrared pulse that drives HHG. ...
Simulating Terahertz Field-Induced Ferroelectricity in Quantum Paraelectric SrTiO3
(American Physical Society, 2022-10)
Recent experiments have demonstrated that light can induce a transition from the quantum paraelectric to the ferroelectric phase of SrTiO3. Here, we investigate this terahertz field-induced ferroelectric phase transition ...
Class of distorted Landau levels and Hall phases in a two-dimensional electron gas subject to an inhomogeneous magnetic field
(American Physical Society, 2022-10)
An analytic closed form solution is derived for the bound states of a two-dimensional electron gas subject to a static, inhomogeneous (1/r in plane decaying) magnetic field, including the Zeeman interaction. The solution ...
Electronic Descriptors for Supervised Spectroscopic Predictions
(American Chemical Society, 2023-03)
Spectroscopic properties of molecules hold great importance for the description of the molecular response under the effect of UV/vis electromagnetic radiation. Computationally expensive ab initio (e.g., MultiConfigurational ...
