Collective dynamics of interacting Ising spins: Exact results for the Bethe lattice
Low temperature dynamic molecules magnet crystal electron spin ground state electronic since the gyration mechanics coupling nuclear
2014/12/19
We study the low temperature dynamics in films made of molecular magnets, i. e. crystals composed of molecules having large electronic spin S in their ground state. The electronic spin dynamics is med...

2011/9/14
Anomalous transport in one-dimensional translation invariant Hamiltonian systems with short range interactions, is shown to belong in general to the KPZ universality class. Exact asymptotic forms for ...

Abstract: Anomalous transport in one dimensional translation invariant Hamiltonian systems with short range interactions, is shown to belong in general to the KPZ universality class. Exact asymptotic ...
Supersymmetry approach to Wishart correlation matrices: Exact results
Wishart correlation matrices
2011/1/18
We calculate the marginal probability density of real and complex Wishart correlation matrices. For deep mathematical reasons,no explicit expression could be obtained for the real case so far.
Horizontal visibility graphs: exact results for random time series
Horizontal visibility graphs random time series
2010/4/2
The visibility algorithm has been recently introduced as a mapping between time series and complex networks. This procedure allows to apply methods of complex network theory for characterizing time se...
Exact results for the criticality of quench dynamics in quantum Ising models
Exact results criticality of quench dynamics quantum Ising models
2010/4/12
Based on the obtained exact results we systematically study the quench dynamics of a one-dimensional spin-1/2 transverse field Ising model with zero- and finite-temperature initial states. We focus on...
