Controlling Valley-Polarisation in Graphene via Tailored Light Pulses
M. S. Mrudul, Gopal Dixit
Analogous to charge and spin, electrons in solids endows an additional degree of freedom: the valley pseudospin. Two-dimensional hexagonal materials such as graphene exhibit two va…
High-harmonic spectroscopy of light-driven nonlinear anisotropic anomalous Hall effect in a Weyl semimetal
Amar Bharti, M. S. Mrudul, Gopal Dixit
Weyl semimetals are promising quantum materials that offer unique topological properties. Lately, it has been shown that laser-driven electron dynamics have characteristic signatur…
Imaging charge-migration in chiral molecules using time-resolved x-ray diffraction
Sucharita Giri, Jean Christophe Tremblay, Gopal Dixit
Four-dimensional imaging of charge migration is crucial to the understanding of several ubiquitous processes in nature. The present work focuses on imaging of charge migration in a…
High harmonic spectroscopy of disorder-induced Anderson localization
Adhip Pattanayak, Á. Jiménez-Galán, Misha Ivanov +1
Exponential localization of wavefunctions in lattices, whether in real or synthetic dimensions, is a fundamental wave interference phenomenon. Localization of Bloch-type functions…
Four-Dimensional Imaging of Lattice Dynamics using Inelastic Scattering
Navdeep Rana, Aditya Prasad Roy, Dipanshu Bansal +1
Time-resolved mapping of lattice dynamics in real- and momentum-space is essential to understand better several ubiquitous phenomena such as heat transport, displacive phase transi…
Role of Majorana Fermions in high-harmonic generation from Kitaev chain
Adhip Pattanayak, Sumiran Pujari, Gopal Dixit
The observation of Majorana fermions as collective excitations in condensed-matter systems is an ongoing quest, and several state-of-the-art experiments have been performed in the…
