Researchers at Princeton, Yale, and the University of Zurich have proposed a theory-based approach to characterize a class of metals that possess exotic electronic properties that could help scientist...
High-precision measurement of the thermal exponent for the three-dimensional XY universality class

2014/12/20
Simulation results are reported for the critical point of the two-component ϕ4 field theory. The correlation-length exponent is measured to high precision with the result ν=0.6717(3). This value ...
On a class of tensor product representations for the orthosymplectic superalgebra

We introduce the spinor representations for osp(m|2n). These generalize the spinors for so(m) and the symplectic spinors for sp(2n) and correspond to representations of the supergroup with supergroup ...
Localization for quasi-periodic Schrodinger operators with dynamics defined by the skew-shift and potential in a Gevrey-class

Abstract: In this paper we present a class of Anderson type operators with independent, non-stationary (non-decaying) random potentials supported on a subset of positive density in the odd-dimensional...
Trends to equilibrium for a class of relativistic diffusions
Relativisic diffusions Relativistic Ornstein-Uhlenbeck process Equilibrium measure
font style='font-size:12px;'>
2011/7/28
Abstract: We address the question of the trends to equilibrium for a large class C of relativistic diffusions. We show the existence of a spectral gap using the Lyapounov method and deduce the exponen...

2011/7/26
Abstract: Preliminary group classification became prominent as an approach to symmetry analysis of differential equations due to the paper by Ibragimov, Torrisi and Valenti [J. Math. Phys. 32, 2988-29...
Anderson-like Transition for a Class of Random Sparse Models in d{leg}2 Dimensions
Random Sparse Models Anderson-like Transition Functional Analysis
font style='font-size:12px;'>
2011/7/26
Abstract: We show that the Kronecker sum of d{\leg}2 copies of a random one-dimensional sparse model displays a spectral transition of the type predicted by Anderson, from absolutely continuous around...

We investigate the physically allowed probabilities for transforming one N-partite W-class state to another by means of local operations assisted with classical communication (LOCC). Recently,Kintas a...
Entropic Inequalities for a Class of Quantum Secret Sharing States
entropic inequalities monotone span programs quantum secret sharing stabilizer states von Neumann entropy
font style='font-size:12px;'>
2010/10/18
It is well-known that von Neumann entropy is nonmonotonic unlike Shannon entropy (which is
monotonically nondecreasing). Consequently, it is difficult to relate the entropies of the subsystems of a g...
