Valley polarization driven by two-color circular fields: a rotating frame and strong-field perspective
Rui E. F. Silva, Olga Smirnova, Misha Ivanov +1
Valley polarization in hexagonal materials driven by the form of the lightwave and its orientation relative to the lattice, rather than solely by the helicity of the driver, has re…
Revealing the Berry phase under the tunneling barrier
Lior Faeyrman, Eduardo B. Molinero, Roni Weiss +12
In quantum mechanics, a quantum wavepacket may acquire a geometrical phase as it evolves along a cyclic trajectory in parameter space. In condensed matter systems, the Berry phase…
Observation of light driven band structure via multi-band high harmonic spectroscopy
Ayelet J. Uzan-Narovlansky, Álvaro Jiménez-Galán, Gal Orenstein +8
Intense light-matter interactions have revolutionized our ability to probe and manipulate quantum systems at sub-femtosecond time scales, opening routes to all-optical control of e…
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…
Lightwave-controlled band engineering in quantum materials
Sambit Mitra, Álvaro Jiménez-Galán, Marcel Neuhaus +4
Stacking and twisting atom-thin sheets create superlattice structures with unique emergent properties, while tailored light fields can manipulate coherent electron transport on ult…
Valleytronics in bulk MoS by optical control of parity and time symmetries
Igor Tyulnev, Álvaro Jiménez-Galán, Julita Poborska +7
The valley degree of freedom of electrons in materials promises routes toward energy-efficient information storage with enticing prospects towards quantum information processing. C…
High-Harmonic Generation with a twist: all-optical characterization of magic-angle twisted bilayer graphene
Eduardo B. Molinero, Anushree Datta, María J. Calderón +2
If we stack up two layers of graphene while changing their respective orientation by some twisting angle, we end up with a system that has striking differences when compared to sin…
A Real-Space Perspective on Dephasing in Solid-State High Harmonic Generation
Graham G. Brown, Álvaro Jiménez-Galán, Rui E. F. Silva +1
We develop and demonstrate a fully real-space perspective on HHG in crystals. Due to Wannier-Stark localization induced on sub-cycle timescales in the presence of a strong field, r…
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…
All-optical valley switch and clock of electronic dephasing
Rui E. F. Silva, Misha Ivanov, Álvaro Jiménez-Galán
2D materials with broken inversion symmetry posses an extra degree of freedom, the valley pseudospin, that labels in which of the two energy-degenerate crystal momenta, K or K', th…
Sub-cycle valleytronics: control of valley polarization using few-cycle linearly polarized pulses
Álvaro Jiménez-Galán, Rui Silva, Olga Smirnova +1
So far, selective excitation of a desired valley in the Brillouin zone of a hexagonal two-dimensional material has relied on using circularly polarized fields. We theoretically dem…
Tracking ultrafast solid-state dynamics using high harmonic spectroscopy
Mina R. Bionta, Elissa Haddad, Adrien Leblanc +9
We establish time-resolved high harmonic generation (tr-HHG) as a powerful spectroscopy for photoinduced dynamics in strongly correlated materials through a detailed investigation…
