Topological Hourglass Dirac Semimetal in the Nonpolar Phase of AgBiO
Bahadur Singh, Barun Ghosh, Chenliang Su +3
Materials with tunable charge and lattice degrees of freedom provide excellent platforms for investigating multiple phases that can be controlled via external stimuli. We show how…
Terahertz modulated optical sideband generation in graphene
Ashutosh Singh, Saikat Ghosh, Amit Agarwal
Exploration of optical non-linear response of graphene predominantly relies on ultra-short time domain measurements. Here we propose an alternate technique that uses frequency modu…
Broadband excitation spectrum of bulk crystals and thin layers of PtTe
Barun Ghosh, Francesca Alessandro, Marilena Zappia +8
We explore the broadband excitation spectrum of bulk PtTe using electron energy loss spectroscopy and density functional theory. In addition to infrared modes related to intrab…
Linear magneto-chiral transport in tilted type-I and type-II Weyl Semimetals
Kamal Das, Amit Agarwal
Berry curvature in Weyl semimetals results in very intriguing magneto-electric and magneto-thermal transport properties. In this paper, we explore the impact of the tilting of the…
Starfruit-like nodal semimetal to Dirac and Weyl semimetal state in CaAuAs
Bahadur Singh, Sougata Mardanya, Chenliang Su +3
Band-crossings occurring on a mirror plane are compelled to form a nodal loop in the momentum space without spin-orbit coupling (SOC). In the presence of other equivalent mirror pl…
Plasmonics with two-dimensional semiconductors "beyond graphene": from basic research to technological applications
Amit Agarwal, Miriam S. Vitiello, Leonardo Viti +2
In this minireview, we explore the main features and the prospect of plasmonics with two-dimensional semiconductors. Plasmonic modes in each class of van der Waals semiconductors h…
