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…
Magnetic Topological Semimetal Phase with Electronic Correlation Enhancement in SmSbTe
Krishna Pandey, Debashis Mondal, John William Villanova +14
The ZrSiS family of compounds hosts various exotic quantum phenomena due to the presence of both topological nonsymmorphic Dirac fermions and nodal-line fermions. In this material…
Low-energy type-II Dirac fermions and spin-polarized topological surface states in transition-metal dichalcogenide NiTe
Barun Ghosh, Debashis Mondal, Chia-Nung Kuo +6
Using spin- and angle- resolved photoemission spectroscopy (spin-ARPES) together with calculations, we demonstrate the existence of a type-II Dirac semimetal stat…
A novel undamped gapless plasmon mode in tilted type-II Dirac semimetal
Krishanu Sadhukhan, Antonio Politano, Amit Agarwal
We predict the existence of a novel long-lived gapless plasmon mode in a type-II Dirac semimetal (DSM). This gapless mode arises from the out-of-phase oscillations of the density f…
Optoelectronic devices, plasmonics and photonics with topological insulators
Antonio Politano, Leonardo Viti, Miriam S. Vitiello
Topological insulators are innovative materials with semiconducting bulk together with surface states forming a Dirac cone, which ensure metallic conduction in the surface plane. T…
Liquid-phase exfoliated indium-selenide flakes and their application in hydrogen evolution reaction
Elisa Petroni, Emanuele Lago, Sebastiano Bellani +12
Single- and few-layered InSe flakes are produced by the liquid-phase exfoliation of beta-InSe single crystals in 2-propanol, obtaining stable dispersions with a concentration as hi…
