Magnetic-Order-Driven Nonlinear Photocurrents in PT-Broken Antiferromagnetic MnS2 and Altermagnetic MnSe2
Fu Li, Rajyavardhan Ray, Xiaoxiong Liu +6
Nonlinear photocurrent responses generally require inversion-symmetry breaking, but its origin can be magnetic rather than structural. In this study, we investigate the bulk photov…
Ab initio design of enhanced and sign-reversible spin Hall and spin Nernst conductivity in skutterudite materials
Saikat Debnath, Babu Baijnath Prasad, Shishir Kumar Pandey
The search for novel materials capable of robust spin-current generation remains an active area of research. Here, we investigate the intrinsic spin Hall and spin Nernst effects in…
Linear and nonlinear optical responses in the chiral multifold semimetal BeAu: A quantum-geometric perspective
Babu Baijnath Prasad, Taisuke Ozaki
Chiral topological semimetals provide a natural platform for exploring how multifold band topology and quantum geometry manifest in optical and photovoltaic responses. BeAu is a ch…
Magnetism-induced second-order nonlinear optical responses in multiferroic BiFeO
Babu Baijnath Prasad, Guan-Fu Liu, Guang-Yu Guo
Nonlinear optical (NLO) responses of noncentrosymmetric nonmagnets have drawn a lot of attention in the past decades because of their significance in materials characterization, gr…
Helicity-tunable spin Hall and spin Nernst effects in unconventional chiral fermion semimetals XY (X=Co, Rh; Y=Si, Ge)
Ting-Yun Hsieh, Babu Baijnath Prasad, Guang-Yu Guo
Transition metal monosilicides CoSi, CoGe, RhSi and RhGe in the chiral cubic B20 structure have recently been found to host unconventional chiral fermions beyond spin-1/2 WFs, and…
Tunable spin Hall and spin Nernst effects in Dirac line-node semimetals XCuYAs (X=Zr, Hf; Y=Si, Ge)
Babu Baijnath Prasad, Guang-Yu Guo
The quaternary arsenide compounds XCuYAs (X=Zr, Hf; Y= Si, Ge) belong to the vast family of the 1111-type quaternary compounds, which possess outstanding physical properties rangin…
Superconductivity at 4K in Pd deficient layered Ta_2Pd_xS_6
Brajesh Tiwari, Babu Baijnath Prasad, Rajveer Jha +2
Here in this short note, we report on the low dimensional 4d and 5d transition metals-chalcogenide based compounds i.e., Ta2PdxS6, showing semiconducting to superconducting transit…
