A refined empirical stability criterion for nonlinear Schroedinger solitons under spatiotemporal forcing
Schroedinger solitons
2011/6/28
We investigate the dynamics of travelling oscillating solitons of the cubic NLS equation under an external spatiotemporal forcing of the form f(x, t) = a exp[iK(t)x].For the case of time-independent f...
We propose a new criterion for judging zero quantum discord for arbitrary bipartite states. A bipartite quantum state has zero quantum discord if and only if all the blocks of its density matrix are n...
The RCCN criterion of separability for states in infinite-dimensional quantum systems
The RCCN criterion of separability states infinite-dimensional quantum systems
2010/9/1
In this paper, the realignment criterion and the RCCN criterion of separability for states in infinite-dimensional bipartite quantum systems are established. Let HA and HB be complex Hilbert spaces wi...
Undecidability as solution to the problem of measurement: fundamental criterion for the production of events
Undecidability solution problem of measurement fundamental criterion production of events

In recent papers we put forth a new interpretation of quantum mechanics, colloquially known as “the Montevideo interpretation”. This interpretation is based on taking into account fundamental limits t...
Criterion for faithful teleportation with an arbitrary multiparticle channel
quantum teleportation multiparticle entanglement teleportation protocol
2009/1/19
We consider quantum teleportation when the given entanglement channel is an arbitrary multiparticle state. A general criterion is presented, which allows one to judge if the channel can be used to tel...
In collaboration with I. Rodnianski we give a geometric criterion for the breakdown of an Einstein vacuum space-time foliated by a constant mean curvature, or maximal, foliation. More precisely we sho...
