Circularly polarized high-order harmonics from solids driven by single-color infrared pulses
6th International Conference on Attosecond Physics, ATTO 2017, Xi'anXi'an, China, 2 Jul 2017 - 7 Jul 20172017-07-022017-07-07  GO
Intraband and interband dynamics generating high-order harmonics in solids exhibit qualitatively different responses to driver-pulse ellipticity, enabling ellipticity-based harmonic cutoff extension. Ab-initio calculations and experiments demonstrate generation of circularly polarized harmonics from single-color pulses..

Ellipticity dependence of high-harmonic generation in solids originating from coupled intraband and interband dynamics
The strong ellipticity dependence of high-harmonic generation (HHG) in gases enables numerous experimental techniques that are nowadays routinely used, for instance, to create isolated attosecond pulses. Extending such techniques to solids requires a fundamental understanding of the microscopic mechanism of HHG. [...]

Creating stable Floquet–Weyl semimetals by laser-driving of 3D Dirac materials
Tuning and stabilizing topological states, such as Weyl semimetals, Dirac semimetals or topological insulators, is emerging as one of the major topics in materials science. Periodic driving of many-body systems offers a platform to design Floquet states of matter with tunable electronic properties on ultrafast timescales. [...]

Washington D.C. : OSA , JTh5B () [10.1364/CLEO_AT.2017.JTh5B.10] special issue: "CLEO: QELS_Fundamental Science 2017"  GO
The various higher-harmonic orders generated in solids exhibit qualitatively different sensitivity to driver-pulse ellipticity, resulting from a different response of intraband and interbanddynamics. Non-zero driver-pulse ellipticity permits harmonic cutoff extension and circularly polarized higher-harmonics..

Impact of the Electronic Band Structure in High-Harmonic Generation Spectra of Solids
An accurate analytic model describing the microscopic mechanism of high-harmonic generation (HHG) in solids is derived. Extensive first-principles simulations within a time-dependent density-functional framework corroborate the conclusions of the model. [...]
