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…
High Harmonic Generation from a Noble Metal
Shima Gholam-Mirzaei, Aleksey Korobenko, Nida Haram +11
High-harmonic generation (HHG) in solids has typically been explored in transparent dielectrics and semiconductors. Metals have long been dismissed due to their strong reflectivity…
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…
Orbital perspective on high-harmonic generation from solids
Á. Jiménez-Galán, C. Bossaer, G. Ernotte +7
High-harmonic generation in solids allows probing and controlling electron dynamics in crystals on few femtosecond timescales, paving the way to lightwave electronics. In the spati…
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…
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…
Role of Spin-Orbit Coupling in High-order Harmonic Generation Revealed by Super-Cycle Rydberg Trajectories
Nicola Mayer, Samuel Beaulieu, Alvaro Jimenez-Galan +7
High-harmonic generation is typically thought of as a sub-laser-cycle process, with the electron's excursion in the continuum lasting a fraction of the optical cycle. However, it w…
Two-photon edge states in photonic topological insulators: topological protection versus degree of entanglement
Konrad Tschernig, Alvaro Jimenez-Galan, Demetrios N. Christodoulides +4
Topological insulators combine insulating properties in the bulk with scattering-free transport along edges, supporting dissipationless unidirectional energy and information flow e…
Reconstruction of attosecond beating by interference of two-photon interband transitions in solids
R. E. F. Silva, Á. Jiménez-Galán
The reconstruction of attosecond beating by interference of two-photon transitions (RABBIT) is one of the most widely used techniques for obtaining both the relative phases of harm…
