Butterfly hysteresis curve is a signature of adiabatic Landau-Zener transition
Mark Vogelsberger, D. A. Garanin, Rolf Schilling
We stress that the so-called butterfly hysteresis curves observed in dynamical magnetization measurements on systems of low-spin magnetic molecules such as V-15 and V-6 are a signa…
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…
Universal mechanism of spin relaxation in solids
E. M. Chudnovsky, D. A. Garanin, R. Schilling
We consider relaxation of a rigid spin cluster in an elastic medium in the presence of the magnetic field. Universal simple expression for spin-phonon matrix elements due to local…
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…
Many-body Landau-Zener effect at fast sweep
D. A. Garanin, R. Schilling
The asymptotic staying probability P in the Landau-Zener effect with interaction is analytically investigated at fast sweep, epsilon = pi Delta^2/(2 hbar v) << 1. We have rigorousl…
