Most of the magnets we encounter daily are made of “ferromagnetic” materials. The north-south magnetic axes of most atoms in these materials are lined up in the same direction, so their collective for...
Infinite disorder scaling of random quantum magnets in three and higher dimensions
Infinite disorder scaling random quantum magnets dimensions
2010/11/11
Using a very efficient numerical algorithm of the strong disorder renormalization group method we have extended the investigations about the critical behavior of the random transverse-field Ising mode...
The spin dynamics of molecular magnets beyond Kubo's linear response theory
nanomagnets spin dynamics Kubo response theory perturbation theory
2010/7/8
The description of quantum dynamics of nanomagnets is a central issue in most applications proposed for those systems. In this paper, we put forward a modified perturbation approach to study the spin ...
