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…
Topological theory of inversion-breaking charge-density-wave monolayer 1\textit{T}-TiSe
Ming-Chien Hsu, Bahadur Singh, Chuang-Han Hsu +3
A charge density wave (CDW) of a nonzero ordering vector couple electronic states at and statically, giving rise to a reduced Bril…
Layer Hall effect in a 2D topological Axion antiferromagnet
Anyuan Gao, Yu-Fei Liu, Chaowei Hu +33
While ferromagnets have been known and exploited for millennia, antiferromagnets (AFMs) were only discovered in the 1930s. The elusive nature indicates AFMs' unique properties: At…
Topological Hall effect in the antiferromagnetic Dirac semimetal EuAgAs
Antu Laha, Ratnadwip Singha, Sougata Mardanya +4
The non-trivial magnetic texture in real space gives rise to the intriguing phenomenon of topological Hall effect (THE), which is relatively less explored in topological semimetals…
High-order Van Hove singularities in cuprates and related high-Tc superconductors
Robert S. Markiewicz, Bahadur Singh, Christopher Lane +1
Two-dimensional (2D) Van Hove singularities (VHSs) associated with the saddle points or extrema of the energy dispersion usually show logarithmic divergences in the density of stat…
Fermi surface studies of a non-trivial topological compound YSi
Vikas Saini, Souvik Sasmal, Ruta Kulkarni +2
The Fermi surface properties of a nontrivial system YSi is investigated by de Haas-van Alphen (dHvA) oscillation measurements combined with the first-principle calculations. Three…
