Topological states in superlattices of HgTe-class materials for engineering three-dimensional flat bands
Rajibul Islam, Barun Ghosh, Giuseppe Cuono +7
In search of materials with three-dimensional flat band dispersions, using {\em ab-initio} computations, we investigate how topological phases evolve as a function of hydrostatic p…
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…
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…
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…
Tunable spin polarization and electronic structure of bottom-up synthesized MoSiN materials
Rajibul Islam, Barun Ghosh, Carmine Autieri +4
Manipulation of spin-polarized electronic states of two-dimensional (2D) materials under ambient conditions is necessary for developing new quantum devices with small physical dime…
Observation of Dynamic Screening in the Excited Exciton States in Multi-layered MoS
Manobina Karmakar, Sayantan Bhattacharya, Subhrajit Mukherjee +6
Excitonic resonance and binding energies can be altered by controlling the environmental screening of the attractive Coulomb potential. Although this screening response is often as…
