Dynamical Magnetic and Nuclear Polarization in Complex Spin Systems: Semi-magnetic II-VI Quantum Dots
Dynamical Magnetic Nuclear Polarization Complex Spin Systems Semi-magnetic II-VI Quantum Dots
2012/2/29
Dynamical magnetic and nuclear polarization in complex spin systems is discussed on the example of transfer of spin from exciton to the central spin of magnetic impurity in a quantum dot in the presen...
On Modeling of Statistical Properties of Classical 3D Spin Glasses
Spin-glass Hamiltonian random network Birkhoff ergodic hypothesis statistic distributions parallel algorithm numerical simulation
2011/8/16
Abstract: We study statistical properties of 3D classical spin glass layer of certain width and infinite length. The 3D spin glass is represented as an ensemble of disordered 1D spatial spin-chains (S...

We consider the Kane-Mele model with spin-orbit coupling supplemented by a Hubbard U term.
On the basis of projective auxiliary eld quantum Monte Carlo simulations on lattice sizes up to 12 12, ...
Fermion- and spin-counting in strongly correlated systems in and out of thermal equilibrium
Fermion spin-counting correlated systems equilibrium
2010/11/8
Atom counting theory can be used to study the role of thermal noise in quantum phase transitions and to monitor the dynamics of a quantum system. We illustrate this for a strongly correlated fermionic...
Spin systems dynamics and faults detection in threshold networks
Spin systems dynamics faults detection threshold networks
2010/10/20
We consider an agent on a fixed but arbitrary node of a known threshold network, with the
task of detecting an unknown missing link/node. We obtain analytic formulas for the probability of success, w...
We discuss the formulation of spin observables associated to a non-relativistic spinning particles in terms of grassmanian differential operators. We use as configuration space variables for the pseud...
