Magnetization quantum tunneling at excited levels for a biaxial spin system in an arbitrarily directed magnetic field
Rong Lu, Su-Peng Kou, Jia-Lin Zhu +2
The quantum tunneling of the magnetization vector between excited levels are studied theoretically in single-domain ferromagnetic nanoparticles with biaxial crystal symmetry placed…
Resonant quantum coherence of magnetization at excited states in nanospin systems with different crystal symmetries
Jia-Lin Zhu, Rong Lu, Su-Pen Kou +2
The quantum interference effects induced by the Wess-Zumino term, or Berry phase are studied theoretically in resonant quantum coherence of magnetization vector between degenerate…
Periodic Bounce for Nucleation Rate at Finite Temperature in Minisuperspace Models
J. -Q. Liang, H. J. W. Müller-Kirsten, Y. -B. Zhang +3
The periodic bounce configurations responsible for quantum tunneling are obtained explicitly and are extended to the finite energy case for minisuperspace models of the Universe. A…
Macroscopic quantum coherence in mesoscopic ferromagnetic systems
S. P. Kou, J. Q. Liang, Y. B. Zhang +1
In this paper we study the Macroscopic Quantum Oscillation (MQO) effect in ferromagnetic single domain magnets with a magnetic field applied along the hard anistropy axis. The leve…
Crossover from thermal hopping to quantum tunneling in Mn_{12}Ac
S. P. Kou, J. Q. Liang, Y. B. Zhang +2
The crossover from thermal hopping to quantum tunneling is studied. We show that the decay rate with dissipation can accurately be determined near the crossover temperature. Be…
Quantum-Classical Phase Transition of Escape rate in Biaxial Spin Particles
Y. -B. Zhang, J. -Q. Liang, H. J. W. Muller-Kirsten +3
The escape rates of the biaxial single domain spin particles with and without an applied magnetic field are investigated. Using the strict potential field description of spin syste…
