Dynamics of systems with isotropic competing interactions in an external field: a Langevin approach
Dynamics of systems isotropic competing interactions external field: a Langevin approach
2010/11/25
We study the Langevin dynamics of a ferromagnetic Ginzburg-Landau Hamiltonian with a competing longrange repulsive term in the presence of an external magnetic field. The model is analytically solved ...
Directed excitation transfer in vibrating chains by external fields
Directed excitation transfer vibrating chains external fields
2010/11/5
We study the coherent dynamics of excitations on vibrating chains. By applying an external field and matching the field strength with the oscillation frequency of the chain it is possible to obtain an...
Entanglement in a Time-Dependent Coupled XY Spin Chain in an External Magnetic Field
Entanglement Time-Dependent Coupled XY Spin Chain External Magnetic Field
2010/10/18
We consider an infinite one dimensional anisotropic XY spin chain with a nearest neighbor time-
dependent Heisenberg coupling J(t) between the spins in presence of a time-dependent magnetic

Entanglement dynamics of two qubits under the influence of external kicks and Gaussian pulses
Entanglement dynamics two qubits influence external kicks Gaussian pulses
2010/10/19
We have investigated the dynamics of entanglement between two spin-1/2 qubits that are sub-
ject to independent kick and Gaussian pulse type external magnetic elds analytically as well as numericall...
Path Integral Evaluation of a Time-Dependent Oscillator in an External Field
Path Integral Propagator Green functions and harmonic oscillator
2010/4/8
The Lagrangian of a system describing the dynamical behaviour of a time-dependent harmonic oscillator is modified and then used to evaluate the Feynman path integral of the oscillator. The path integr...
