Counterdiabatic driving for long-lived singlet state preparation
Abhinav Suresh, Vishal Varma, Priya Batra +1
The quantum adiabatic method, which maintains populations in their instantaneous eigenstates throughout the state evolution, is an established and often a preferred choice for stat…
Giant spin Nernst effect in a two-dimensional antiferromagnet due to magnetoelastic coupling-induced gaps and interband transitions between magnon-like bands
D. -Q. To, C. Y. Ameyaw, A. Suresh +7
We analyze theoretically the origin of the spin Nernst and thermal Hall effects in FePS3 as a realization of two-dimensional antiferromagnet (2D AFM). We find that a strong magneto…
Quantum-classical approach to spin and charge pumping and the ensuing radiation in THz spintronics: Example of ultrafast-light-driven Weyl antiferromagnet MnSn
Abhin Suresh, Branislav K. Nikolic
The interaction of fs light pulses with magnetic materials has been intensely studied for more than two decades in order to understand ultrafast demagnetization in single magnetic…
Electron-mediated entanglement of two distant macroscopic ferromagnets within a nonequilibrium spintronic device
A. Suresh, R. D. Soares, P. Mondal +6
Using the nascent concept of quantum spin-transfer torque [A. Zholud et al., Phys. Rev. Lett. {\bf 119}, 257201 (2017); M. D. Petrović {\em et al.}, Phys. Rev. X {\bf 11}, 021062 (…
Spin pumping from antiferromagnetic insulator spin-orbit-proximitized by adjacent heavy metal: A first-principles Floquet-nonequilibrium Green's function study
Kapildeb Dolui, Abhin Suresh, Branislav K. Nikolic
Motivated by recent experiments [P. Vaidya {\em et al.}, Science {\bf 368}, 160 (2020)] on spin pumping from sub-THz radiation-driven uniaxial antiferromagnetic insulator (AFI) MnF…
Quantum many-body states and Green functions of nonequilibrium electron-magnon systems: Localized spin operators vs. their mapping to Holstein-Primakoff bosons
Utkarsh Bajpai, Abhin Suresh, Branislav K. Nikolic
The operators of localized spins within a magnetic material commute at different sites of its lattice and anticommute on the same site, so they are neither fermionic nor bosonic op…
Magnon versus electron mediated spin-transfer torque exerted by spin currents across antiferromagnetic insulator to switch magnetization of adjacent ferromagnetic metal
Abhin Suresh, Marko D. Petrovic, Utkarsh Bajpai +2
The recent experiment [Y. Wang et al., Science 366, 1125 (2019)] on magnon-mediated spin-transfer torque (MSTT) was interpreted in terms of a picture where magnons are excited with…
Magnon-driven chiral charge and spin pumping and electron-magnon scattering from time-dependent quantum transport combined with atomistic spin dynamics theory
Abhin Suresh, Utkarsh Bajpai, Branislav K. Nikolic
Using newly developed quantum-classical hybrid framework, we investigate interaction between spin-polarized conduction electrons and a single spin wave (SW) coherently excited with…
Induced Polarization from Birefringent Pulse Splitting in Magnetoionic Media
Akshay Suresh, James M. Cordes
Birefringence in ionized, magnetized media is usually measured as Faraday rotation of linearly polarized radiation. However, pulses propagating through regions with very large Fara…
