We investigate the possibility of having horizons inside various classical field configurations. Using the implicit function theorem, we show that models satisfying a certian set of criteria allow for...
Worm Algorithms for Classical Statistical Models
High temperature expansion, monte carlo simulation, dynamic critical
2014/12/22
We show that high-temperature expansions provide a basis for the novel approach to efficient Monte Carlo simulations. “Worm” algorithms utilize the idea of updating closed-path configurations (produce...

The standard picture of the loop expansion associates a factor of ˉh with each loop, suggesting that the tree diagrams are to be associated with classical physics, while loop effects are quantum mecha...

This is a chapter of the multi-author book “Understanding Quantum Phase Transitions,” edited by Lincoln Carr and published by Taylor & Francis. In this chapter, we give a general introduction to the w...
Classical phases and quantum angles in the description of interfering Bose-Einstein condensates
Condensate random variables measurements
2014/12/19
The interference of two Bose-Einstein condensates, initially in Fock states, can be described in terms of their relative phase, treated as a random unknown variable. This phase can be understood eithe...

We study amplitudes of five-wave interactions for evolution Hamiltonian equations differ from the KdV equation by the form of dispersion law. We find that five-wave amplitude is canceled for all three...
