Nonlinear bulk photocurrent probe Z2 topological phase transition
Debasis Dutta, Raihan Ahammed, Yingdong Wei +4
Detecting topological phase transitions in bulk is challenging due to the limitations of surface sensitive probes like ARPES. Here, we demonstrate that nonlinear bulk photocurrents…
Collective plasmonic modes in the chiral multifold fermionic material CoSi
Debasis Dutta, Barun Ghosh, Bahadur Singh +4
Plasmonics in topological semimetals offers exciting opportunities for fundamental physics exploration as well as for technological applications. Here, we investigate plasmons in t…
Photonic Topological Transitions and Epsilon-Near-Zero Surface Plasmons in Type-II Dirac Semimetal NiTe
Carlo Rizza, Debasis Dutta, Barun Ghosh +8
Compared to artificial metamaterials, where nano-fabrication complexities and finite-size inclusions can hamper the desired electromagnetic response, several natural materials like…
