Coulomb Drag Between Parallel Ballistic Quantum Wires

, 1999
The Coulomb drag between parallel, {\it ballistic} quantum wires is studied theoretically in the presence of a perpendicular magnetic field B. The transresistance R_D shows peaks as a function of the Fermi level and splitting energy between the 1D ...

Tensor models and embedded Riemann surfaces

, 2011
Tensor models and, more generally, group field theories are candidates for higher-dimensional quantum gravity, just as matrix models are in the 2d setting. With the recent advent of a 1/N-expansion for coloured tensor models, more focus has been given to

Solution to Several Split Quaternion Matrix Equations

Mathematics
Split quaternions have various applications in mathematics, computer graphics, robotics, physics, and so on. In this paper, two useful, real representations of a split quaternion matrix are proposed. Based on this, we derive their fundamental properties. Then, via the real representation method, we obtain the necessary and sufficient conditions for the

Minimizing Computation and Communication Costs of Two-Sided Secure Distributed Matrix Multiplication under Arbitrary Collusion Pattern

Entropy
This paper studies the problem of minimizing the total cost, including computation cost and communication cost, in the system of two-sided secure distributed matrix multiplication (SDMM) under an arbitrary collusion pattern. In order to perform SDMM, the

Additional moments and x-space approximations of four-loop splitting functions in QCD

Physics Letters B
We have extended our previous computations of the even-N moments of the flavour-singlet four-loop splitting functions to N=12 for the pure-singlet quark case and N=10 for all other cases.

Summability of alterations of convergent series

International Journal of Mathematics and Mathematical Sciences, 1981
The effect of splitting, rearrangement, and grouping series alterations on the summability of a convergent series by ℓ−ℓ and cs−cs matrix methods is studied.

Democratic neutrino mass matrix from generalized Fridberg-Lee model with the perturbative solar mass splitting

, 2015
We propose a phenomenological model of the Dirac neutrino mass matrix based on the Fridberg-Lee neutrino mass model at a special point. In this case, the Fridberg-Lee model reduces to the Democratic mass matrix with the $S_3$ permutation family symmetry.

The 1 → 3 massive splitting functions from QCD factorization and SCET

Journal of High Energy Physics
Splitting functions are universal functions describing the collinear dynamics of gauge theories, and as such are crucial ingredients for a wide variety of calculations in perturbative QCD.

R-Phase Transformation Evolution in NiTi SMA Wires Studied via the Internal Friction Technique

Crystals
The specific damping capacity variation of heat-treated NiTi was observed during a pseudoelasticity test. The detailed B2 → R-phase transformation process in cold-drawn NiTi wires undergoing middle-temperature aging was studied via X-ray diffraction ...

Fast crosstalk precoder based on structured matrix splitting for downstream transmission

Tongxin xuebao, 2009
Based on special line position,a novel precoder of cancellation crosstalk for downstream transmission was proposed.As the new method needs only two order matrix inversion,the precoder had a much lower computational com-plexity and was easy for ...
