Engineering Nonlinear Optical Responses via Inversion Symmetry Breaking in Bilayer Bi2Se3
Vineet Kumar Sharma, Alana Okullo, Barun Ghosh +2
Paucity of naturally occurring noncentrosymmetric materials is stimulating growing interest in engineered two-dimensional systems for nonlinear optical applications. Here, we show…
Layer-dependent antiferromagnetic Chern and axion insulating states in UOTe
Sougata Mardanya, Barun Ghosh, Mengke Liu +8
Magnetic topological insulators have received significant interest due to their dissipationless edge states, which promise advances in energy-efficient electronic transport. Howeve…
Giant Shift Current in Electrically-Tunable Superlattice Bilayer Graphene
Nabil Atlam, Swati Chaudhary, Arpit Raj +4
Recent introduction of superlattice potentials has opened new avenues for engineering tunable electronic band structures featuring topologically nontrivial moiré-like bands. Here w…
Observation of the Axion quasiparticle in 2D MnBiTe
Jian-Xiang Qiu, Barun Ghosh, Jan Schütte-Engel +32
In 1978, Wilczek and Weinberg theoretically discovered a new boson-the Axion-which is the coherent oscillation of the field in QCD. Its existence can solve multiple fundamental…
Diverse electronic topography in a distorted kagome metal LaTi3Bi4
Anup Pradhan Sakhya, Brenden R. Ortiz, Barun Ghosh +9
Recent reports on a family of kagome metals of the form LnTi3Bi4 (Ln = Lanthanide) has stoked interest due to the combination of highly anisotropic magnetism and a rich electronic…
