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…
IRLCov19: A Large COVID-19 Multilingual Twitter Dataset of Indian Regional Languages
Deepak Uniyal, Amit Agarwal
Emerged in Wuhan city of China in December 2019, COVID-19 continues to spread rapidly across the world despite authorities having made available a number of vaccines. While the cor…
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…
Competing magnetic interactions and magnetocaloric effect in HoSn
Suman Mondal, Pushpendra Yadav, Anan Bari Sarkar +4
The rare-earth intermetallic compound HoSn demonstrates fascinating magnetic properties which include temperature-driven multiple magnetic transitions and field driven meta…
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…
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…
