Magneto-elastic waves in crystals of magnetic molecules
C. Calero, E. M. Chudnovsky, D. A. Garanin
We study magneto-elastic effects in crystals of magnetic molecules. Coupled equations of motion for spins and sound are derived and the possibility of strong resonant magneto-acous…
Rabi oscillations from ultrasound in spin systems
C. Calero, E. M. Chudnovsky
It is shown that ultrasound in the GHz range can generate space-time Rabi oscillations between spin states of molecular magnets. We compute dynamics of the magnetization generated…
Relaxation of the Electron Spin in Quantum Dots Via One- and Two-Phonon Processes
C. Calero, E. M. Chudnovsky, D. A. Garanin
We have studied direct and Raman processes of the decay of electron spin states in a quantum dot via radiation of phonons corresponding to elastic twists. Universal dependence of t…
Two-phonon spin-lattice relaxation of rigid atomic clusters
C. Calero, E. M. Chudnovsky, D. A. Garanin
Spin-phonon relaxation due to two-phonon processes of a spin cluster embedded in an elastic medium has been studied. For the case of uniaxial anisotropy, relaxation rates due to Ra…
Field Dependence of the Electron Spin Relaxation in Quantum Dots
Carlos Calero, E. M. Chudnovsky, D. A. Garanin
Interaction of the electron spin with local elastic twists due to transverse phonons has been studied. Universal dependence of the spin relaxation rate on the strength and directio…
Quantum dynamics of a nanomagnet in a rotating field
C. Calero, E. M. Chudnovsky, D. A. Garanin
Quantum dynamics of a two-state spin system in a rotating magnetic field has been studied. Analytical and numerical results for the transition probability have been obtained along…
