Helicity-engineered nonlinear optical responses in photo-excited topological semimetals
Roshan Kumar Thakur, Prachi Venkat, Amar Bharti +1
Topological materials provide a transformative arena for light-driven control of electronic motion; yet, direct manipulation of electron dynamics on sub-cycle timescale remains a s…

Coherent control of chirality in Weyl semimetals
Amar Bharti, Margarita Khokhlova, Misha Ivanov +1
Weyl fermions in inversion-symmetric Weyl semimetals occur in pairs of opposite chirality, leading to symmetric optical responses under circularly-polarised light and a vanishing n…
