Experiments show that a collection of bouncing fluid droplets can behave like a microscopic system of spins — the intrinsic angular momenta of particles. This discovery could lead to a better understa...

Diagonalization-free implementation of spin relaxation theory for large spin systems
NMR EPR relaxation simulation spin dynamics
2011/3/1
The Liouville space spin relaxation theory equations are reformulated in such a way as to avoid the computationally expensive Hamiltonian diagonalization step, replacing it by numerical evaluation of ...
Homogeneous populations of oscillators have recently been shown to exhibit stable coexistence
of coherent and incoherent regions. Generalizing the concept of chimera states to the context of order-di...
Absence of magnetism in continuous-spin systems with long-range antialigning forces
magnetism continuous-spin systems long-range antialigning forces
2010/11/12
We consider continuous-spin models on the $d$-dimensional hypercubic lattice with the spins $\sigma_x$ \emph{a priori} uniformly distributed over the unit sphere in $\R^n$ (with $n\ge2$) and the inter...
Ruelle-Lanford functions for quantum spin systems
Ruelle-Lanford functions quantum spin systems
2010/10/27
We prove a large deviation principle for the expectation of macroscopic observables in quantum (and classical) Gibbs states. Our proof is based on Ruelle-Lanford functions [20, 34] and direct subaddit...
Low energy states dynamic of entanglement for spin systems
Low energy states dynamic of entanglement spin systems
2010/10/20
We have composed the ideas of quantum renormalization group and quantum information by
exploring the low energy states dynamic of entanglement resources of a system close to its quantum critical poin...
Evaluation of ground state entanglement in spin systems with the random phase approximation
Evaluation ground state entanglement spin systems random phase approximation
2010/10/19
We discuss a general treatment based on the mean field plus random phase approximation (RPA)
for the evaluation of subsystem entropies and negativities in ground states of spin systems. The approach ...
Equivariant quantization of spin systems

2010/12/3
We investigate the geometric and conformally equivariant quantizations of the supercotangent
bundle of a pseudo-Riemannian manifold (M,g), which is a model for the phase space of a classical spin par...
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...

Relationship between probabilities of the state transfers and entanglements in spin systems with simple geometrical configurations
probabilities of the state transfers entanglements in spin systems geometrical configurations
2010/4/9
In this paper we derive analytical relations between probabilities of the excited state transfers and entanglements calculated by both the Wootters and positive partial transpose (PPT) criteria for th...
Entanglement vs. gap for one-dimensional spin systems
Entanglement one-dimensional spin systems
2010/4/8
We study the relationship between entanglement and spectral gap for local Hamiltonians in one dimension. The area law for a one-dimensional system states that for the ground state, the entanglement of...
