Unconventional superconducting pairing in a B20 Kramers Weyl semimetal
Sougata Mardanya, Mehdi Kargarian, Rahul Verma +6
Topological superconductors present an ideal platform for exploring nontrivial superconductivity and realizing Majorana boundary modes in materials. However, finding a single-phase…
Nonlinear Valley Hall Effect
Kamal Das, Koushik Ghorai, Dimitrie Culcer +1
The valley Hall effect arises from valley contrasting Berry curvature and requires inversion symmetry breaking. Here, we propose a nonlinear mechanism to generate a valley Hall cur…
Room Temperature Ferroelectricity, Ferromagnetism, and Anomalous Hall Effect in Half-metallic Monolayer CrTe
Imran Ahamed, Atasi Chakraborty, Pushpendra Yadav +4
Two-dimensional materials hosting ferroelectricity and ferromagnetism are crucial for low-power and high-speed information processing technologies. However, intrinsic 2D multiferro…
Observation of highly anisotropic bulk dispersion and spin-polarized topological surface states in CoTe2
Atasi Chakraborty, Jun Fujii, Chia-Nung Kuo +4
We present CoTe2 as a new type-II Dirac semimetal supporting Lorentz symmetry violating Dirac fermions in the vicinity of the Fermi energy. By combining first principle ab-initio c…
Discovery of a magnetic Dirac system with large intrinsic non-linear Hall effect
Federico Mazzola, Barun Ghosh, Jun Fujii +9
Magnetic materials exhibiting topological Dirac fermions are attracting significant attention for their promising technological potential in spintronics. In these systems, the comb…
Observation of time-reversal symmetric Hall effect in graphene-WSe2 heterostructures at room temperature
Priya Tiwari, Divya Sahani, Atasi Chakraborty +5
In this letter, we provide experimental evidence of the time-reversal symmetric Hall effect in a mesoscopic system, namely high-mobility graphene/WSe heterostructures. This lin…
