Long-range and steady-state entanglement of nitrogen vacancy centers using microwaves as a drive and synthetic antiferromagnet as a dissipator

Federico Garcia-Gaitan, Branislav K. Nikolic

The search for optimal schemes and dissipative environments that can mediate long-range entanglement between two distant nitrogen-vacancy centers (NVCs) in diamond has been the sub…

FermiLink: An Agent Harness for Multidomain Scientific Simulations

Gang Meng, Andres Felipe Bocanegra Vargas, Xinwei Ji +7

Artificial-intelligence (AI) agent harnesses have been developed for autonomous scientific simulations, but most current agent harnesses are tested on single or a small set of soft…

Fate of entanglement in open quantum spin liquid: Time evolution of its genuine multipartite negativity upon sudden coupling to a dissipative bosonic environment

Federico Garcia-Gaitan, Branislav K. Nikolic

Many-body entanglement properties of quantum spin liquids (QSLs), persisting at arbitrarily long distances, have been intensely explored over the past two decades, but mostly for Q…

Nonclassical dynamics of Néel vector and magnetization accompanied by THz and high-harmonic radiation from ultrafast-light-driven NiO antiferromagnet insulator

Federico Garcia-Gaitan, Adrian E. Feiguin, Branislav K. Nikolic

Ultrafast-light-driven strongly correlated antiferromagnetic insulators, such as prototypical NiO with large energy gap 4 eV, have recently attracted experimental attention using e…

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…

Fate of entanglement in magnetism under Lindbladian or non-Markovian dynamics and conditions for their transition to Landau-Lifshitz-Gilbert classical dynamics

Federico Garcia-Gaitan, Branislav K. Nikolic

It is commonly assumed in spintronics and magnonics that localized spins within antiferromagnets are in the Néel ground state (GS), as well as that such state evolves, when pushed…
