Spin dynamics in the optical cycle of single nitrogen-vacancy centres in diamond
Spin dynamics the optical cycle single nitrogen-vacancy centres diamond
2010/10/29
We investigate spin-dependent decay and intersystem crossing in the optical cycle of single negatively-charged nitrogen-vacancy (NV) centres in diamond. We use spin control and pulsed optical excitati...
Spin-echo experiments are often said to constitute an instant of anti-thermodynamic behavior
in a concrete physical system that violates the second law of thermodynamics. We argue that a
proper ther...
Tripartite thermal correlations in an inhomogeneous spin-star system
Tripartite thermal correlations inhomogeneous spin-star system
2010/10/20
We exploit the tripartite negativity to study the thermal correlations in a tripartite system, that is the three outer spins interacting with the central one in a spin-star system. We analyze the depe...
The Canonical Thermodynamic Formalism: Chaotic States of Spin and Gauge Systems
Thermodynamic Formalism Gauge Systems Spin
2010/4/15
The three-site antiferromagnetic Ising, Q-state Potts (Q<2) and Z(N) gauge models in some temperatures and external fields have a chaotic behavior. We investigate the thermodynamic formalism of these ...
