Laser-enhanced magnetism in SmFeO
Mohsen Yarmohammadi, Marin Bukov, Vadim Oganesyan +1
To coherently enhance inherent weak magnetic interactions in rare-earth orthoferrite SmFeO as a functional material for spintronic applications, we simulate the dissipative spi…
Nonequilibrium phononic first-order phase transition in a driven fermion chain
Mohsen Yarmohammadi, Marin Bukov, Michael H. Kolodrubetz
We study the direct laser drive of infrared-active phonons that are quadratically coupled to a spinless fermion chain. Feedback is incorporated by phonon dressing of the electronic…
Strong-coupling magnetophononics: Self-blocking, phonon-bitriplons, and spin-band engineering
M. Yarmohammadi, M. Krebs, G. S. Uhrig +1
Magnetophononics, the modulation of magnetic interactions by driving infrared-active lattice excitations, is emerging as a key mechanism for the ultrafast dynamical control of both…
Truncated Wigner approximation for the bosonic model of large spin baths
Mohsen Yarmohammadi, Katrin Bolsmann, Yvonne Ribbeheger +2
The central spin model has a wide applicability, it is ideally suited to describe a small quantum system, for instance a quantum bit, in contact to a bath of spins, e.g., nuclear s…
Noncollinear twisted RKKY interaction on the optically driven SnTe(001) surface
Mohsen Yarmohammadi, Marin Bukov, Michael H. Kolodrubetz
The nontrivial spin texture on the (001) surface of topological crystalline insulator SnTe hosts exotic scientific importance and spintronic applications. Here, we study the effect…
Giant Resonant Self-Blocking in Magnetophononically Driven Quantum Magnets
M. Yarmohammadi, M. Krebs, G. S. Uhrig +1
Magnetophononics, the modulation of magnetic interactions by driven infrared-active lattice excitations, is emerging as a key mechanism for the ultrafast dynamical control of both…
Dynamic mean-field theory for dense spin systems at infinite temperature
Timo Gräßer, Philip Bleicker, Dag-Björn Hering +2
A dynamic mean-field theory for spin ensembles (spinDMFT) at infinite temperatures on arbitrary lattices is established. The approach is introduced for an isotropic Heisenberg mode…
Dynamical properties of a driven dissipative dimerized chain
M. Yarmohammadi, C. Meyer, B. Fauseweh +2
We consider the dynamical properties of a gapped quantum spin system coupled to the electric field of a laser, which drives the resonant excitation of specific phonon modes that mo…
