Tight-binding and density-functional study of the Raman tensor in two-dimensional massive Dirac fermion systems
Selçuk Parlak, Abhishek Kumar, Runhan Li +2
Recently, two unusual features were theoretically predicted for the Raman response of out-of-plane phonons in magnetic two-dimensional materials hosting massive Dirac fermions. Fir…
Unveiling Intrinsic Triplet Superconductivity in Noncentrosymmetric NbRe through Inverse Spin-Valve Effects
F. Colangelo, M. Modestino, F. Avitabile +7
NbRe is a non-centrosymmetric superconductor that has been proposed as a candidate for intrinsic spin-triplet pairing. However, a conclusive demonstration of triplet pairing in NbR…
Resonant Edelstein and inverse-Edelstein effects, charge-to-spin conversion, and spin pumping from chiral-spin modes
Mojdeh Saleh, Abhishek Kumar, Dmitrii L. Maslov +1
Spin-orbit coupling in systems with broken inversion symmetry gives rise to the Edelstein effect, which is the spin polarization induced by an electric field or current, and the in…
Massive Dirac-Pauli physics in lead-halide perovskites
Abhishek Shiva Kumar, Mikhail Maslov, Mikhail Lemeshko +2
In standard quantum electrodynamics (QED), the so-called non-minimal (Pauli) coupling is suppressed for elementary particles and has no physical implications. Here, we show that th…
Effects of electron correlation on resonant Edelstein and inverse-Edelstein effects
Mojdeh Saleh, Abhishek Kumar, Dmitrii L. Maslov +1
Spin-orbit coupling in systems with broken inversion symmetry gives rise to the Edelstein effect, which is the induced spin polarization in response to an applied electric field or…
