DOI: 10.1063/5.0042788
Abstract: In this paper, we present the ingredients that allow the building-up of the elastic model, one of the approaches that successfully describes the phenomena observed in complex spin-crossover systems at both the micro- and macroscopic… read more here.

DOI: 10.1103/physreva.105.043106
Abstract: Within the Floquet theory of periodically driven quantum systems, the nonlinear single-spin dynamics under pulse of a circularly polarized electromagnetic field is analyzed. It is demonstrated that the field, first, lifts the spin degeneracy and,… read more here.

DOI: 10.1103/physrevb.104.l020510
Abstract: We provide a unified interpretation of both paramagnon and plasmon modes in high-Tc copperoxides, and verify it quantitatively against available resonant inelastic x-ray scattering (RIXS) data across the hole-doped phase diagram. Three-dimensional extended Hubbard model,… read more here.

DOI: 10.1103/physrevb.107.144417
Abstract: Understanding the spin-relaxation mechanism of single adatoms is an essential step towards creating atomic magnetic memory bits or even qubits. Here we present an essentially parameter-free theory by combining \textit{ab-initio} electronic and vibrational properties with… read more here.

DOI: 10.1103/physrevlett.120.060408
Abstract: We develop the contact theory for spin-orbit-coupled Fermi gases. By using a perturbation method, we derive analytically the universal two-body behavior at short distance, which does not depend on the short-range details of interatomic potentials.… read more here.
