Optimized random phase encryption
(Optical Society of America, 2018-08)
We propose for the first time, to the best of our knowledge, the use of optimized random phases (ORAPs) in a double random phase encryption scheme (DRPE). In DRPE schemes the convolution between two random phase functions ...
Strong-randomness infinite-coupling phase in a random quantum spin chain
(American Physical Society - APSCollege Park, 2014-01)
We study the ground-state phase diagram of the Ashkin-Teller random quantum spin chain by means of a generalization of the strong-disorder renormalization group. In addition to the conventional paramagnetic and ferromagnetic ...
The finite temperature random phase approximation as a coupled-channel problem and the implementation of the single-channel random phase approximation (SCRPA) for the He atom in a finite temperature dense plasma

The van Hemmen model and effect of random crystalline anisotropy field
(Elsevier B.V., 2016-01-15)
In this work, we have presented the generalized phase diagrams of the van Hemmen model for spin S=1 in the presence of an anisotropic term of random crystalline field. In order to study the critical behavior of the phase ...
Partially Observed Markov Random Fields Are Variable Neighborhood Random Fields
(SPRINGERNEW YORK, 2012)
The present paper has two goals. First to present a natural example of a new class of random fields which are the variable neighborhood random fields. The example we consider is a partially observed nearest neighbor binary ...
