p-Wave Orbital Angular Momentum Texture in a Chiral Crystal
Dongjin Oh, Chiara Pacella, Xiangyu Luo +8
The spin and orbital angular momentum (SAM and OAM) are conceptually analogous, yet their roles in condensed matter systems have not been often treated on equal footing. While SAM…
Probing sliding ferroelectricity in bilayer T-WTe with high-harmonic generation
Elias Greil, Alba de las Heras, Angel Rubio +1
High-harmonic generation is a sensitive all-optical probe of symmetry and electron dynamics in solids. Here, we use first-principles time-dependent density functional theory (TDDFT…
Symmetry-Driven Floquet Engineering in Multivalley SnS
Sotirios Fragkos, Benshu Fan, Umberto De Giovannini +5
Coherent interactions between time-periodic electromagnetic fields and materials offer a powerful platform for engineering light-matter hybrid Floquet states with tailored function…
Pulse-duration-sensitive high harmonics and attosecond locally-chiral light from a chiral topological Weyl semimetal
Alba de las Heras, Ofer Neufeld, Angel Rubio
High harmonic generation (HHG) in solids results from an interplay between intraband acceleration and electron-hole recombination driven by a high-intensity laser pulse. Here, we t…
Quantum interference and occupation control in high harmonic generation from monolayer
Minjeong Kim, Taeho Kim, Anna Galler +13
Two-dimensional hexagonal materials such as transition metal dichalcogenides exhibit valley degrees of freedom, offering fascinating potential for valley-based quantum computing an…
