Magnetoelasticity-driven phase inversion of ultrafast spin precession in NixFe100-x thin films
Journal of Science: Advanced Materials and Devices, 2023 We present strong evidence for the deterministic role of magnetoelasticity in ultrafast spin dynamics of ferromagnetic NixFe100-x alloy films. Without a change in the crystal structure, we observed sudden π-phase inversion of the spin precession in the ...

Non-Markovian dynamics control of spin-1/2 system interacting with magnets
New Journal of Physics, 2021 The unavoidable interaction of an open quantum system with its surrounding environment may follow non-Markovian dynamics behavior, which causes its memory effects to play a key role in many quantum technologies.

AIP Advances, 2019 We explored, by micromagnetic simulations, a new-concept RS (reset-set) latch logic operation based on magnetic-dot networks comprised of physically separated but dipolar-coupled three disks in magnetic-vortex states. To devise this robust RS latch logic

The hardness of quantum spin dynamics
CoRR, 2023 Recent experiments demonstrated quantum computational advantage in random circuit sampling and Gaussian boson sampling. However, it is unclear whether these experiments can lead to practical applications even after considerable research effort. On the other hand, simulating the quantum coherent dynamics of interacting spins has been considered as a ...

Anomalous coherent and dissipative coupling in dual photon-magnon hybrid resonators
Scientific ReportsWe explored the distinctive behavior of coherent and dissipative photon-magnon coupling (PMC) in dual hybrid resonators, each incorporating an Inverted Split-Ring Resonator (ISRR) paired with a Yttrium Iron Garnet (YIG) film, positioned in close ...

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Nanomaterials, 2023 Exciton recombination and spin dynamics in (In,Al)As/AlAs quantum dots (QDs) with indirect band gap and type-I band alignment were studied. The negligible (less than 0.2 μeV) value of the anisotropic exchange interaction in these QDs prevents the mixing ...

Hydrodynamics Formalism with Spin Dynamics [PDF]
Acta Physica Polonica B Proceedings Supplement, 2021 We review the key steps of the relativistic fluid dynamics formalism with spin degrees of freedom initiated recently. We obtain equations of motion of the expansion of the system from the underlying definitions of quantum kinetic theory for the equilibrium phase space distribution functions.
