Electric polarization induced by magnons and magnon Nernst effects
D. Quang To, Federico Garcia-Gaitan, Yafei Ren +5
Magnons offer a promising path toward energy-efficient information transmission and the development of next-generation classical and quantum computing technologies. However, method…
Schwinger-Keldysh non-perturbative field theory of open quantum systems beyond the Markovian regime: Application to spin-boson and spin-chain-boson models
Felipe Reyes-Osorio, Federico Garcia-Gaitan, David J. Strachan +3
We develop a unified framework for open quantum systems composed of many mutually interacting quantum spins, or any isomorphic systems like qubits and qudits, surrounded by one or…
Magnon spectrum of altermagnets beyond linear spin wave theory: Magnon-magnon interactions via time-dependent matrix product states vs. atomistic spin dynamics
Federico Garcia-Gaitan, Ali Kefayati, John Q. Xiao +1
The energy-momentum dispersion of magnons, as collective low-energy excitations of magnetic material, is computed from an effective quantum spin Hamiltonian but simplified via line…
