Equilibrium susceptibilities of superparamagnets: longitudinal & transverse, quantum & classical
J. L. Garcia-Palacios, J. B. Gong, F. Luis
The equilibrium susceptibility of uniaxial paramagnets is studied in a unified framework which permits to connect traditional results of the theory of quantum paramagnets, $\Sm=1/2…
On the Statics and Dynamics of Magneto-Anisotropic Nanoparticles
J. L. Garcia-Palacios
Sec I - Introduction Sec II - Equilibrium properties: generalities and methodology Sec III - Equilibrium properties: some important quantities Sec IV - Dynamical properties: heuris…
Introduction to the theory of stochastic processes and Brownian motion problems
J. L. Garcia-Palacios
These notes are an introduction to the theory of stochastic processes based on several sources. The presentation mainly follows the books of van Kampen and Wio, except for the intr…
Non-linear response of single-molecule magnets: field-tuned quantum-to-classical crossovers
R. Lopez-Ruiz, F. Luis, A. Millan +3
Quantum nanomagnets can show a field dependence of the relaxation time very different from their classical counterparts, due to resonant tunneling via excited states (near the anis…
Solving spin quantum-master equations with matrix continued-fraction methods: application to superparamagnets
J. L. Garcia-Palacios, D. Zueco
We implement continued-fraction techniques to solve exactly quantum master equations for a spin with arbitrary S coupled to a (bosonic) thermal bath. The full spin density matrix i…
Perturbative continued-fraction method for weakly interacting Brownian spins and dipoles
J. L. Garcia-Palacios
The continued-fraction method was developed systematically by Risken and co-workers to solve problems of arbitrary fluctuations in nonlinear systems. However, this efficient techni…
