How massless are Weyl fermions in Weyl semimetals?
Amar Bharti, Misha Ivanov, Gopal Dixit
Circularly polarized light fails to generate currents in inversion-symmetric Weyl semimetals with degenerate Weyl nodes. While each node generates current with the direction depend…
Role of topological charges in the nonlinear-optical response from Weyl semimetals
Amar Bharti, Gopal Dixit
The successful realization of the topological Weyl semimetals has revolutionized contemporary physics. In recent years, multi-Weyl semimetals, a class of topological Weyl semimetal…
All-Optical Ultrafast Valley Switching in Two-Dimensional Materials
Navdeep Rana, Gopal Dixit
Electrons in two-dimensional materials possess an additional quantum attribute, the valley pseudospin, labelled as and -- analogous to the spin u…
Generation of Circularly-Polarised High-Harmonics with Identical Helicity in Two-Dimensional Materials
Navdeep Rana, M. S. Mrudul, Gopal Dixit
Generation of circularly-polarized high-harmonics with the same helicity to all orders is indispensable for chiral-sensitive spectroscopy with attosecond temporal resolution. Solid…
Tailoring polarisation of attosecond pulses via co-rotating bicircular laser fields
Rambabu Rajpoot, Amol R. Holkundkar, Navdeep Rana +1
The present work introduces a robust way to generate attosecond pulses with tunable ellipticity via high-order harmonic generation by co-rotating bicircular laser fields. T…
Charge Migration in Heterocyclic Five-Membered Rings
Sucharita Giri, Gopal Dixit, Jean Christophe Tremblay
This contribution presents numerical simulations of N-electron dynamics in heterocyclic five-membered ring molecules to shed light on the effect of molecular symmetry on charge mig…
