New developments on calculating and measuring ac losses in composite superconductors [PDF]

, 1992
A method for the complete numerical solution of the Maxwell equation for a multifilamentary wire carrying a transport current and subject to applied fields of arbitrary direction, where both current and applied fields have arbitrary time dependence, has ...

Symplectic integrators for index one constraints [PDF]

, 2012
We show that symplectic Runge-Kutta methods provide effective symplectic integrators for Hamiltonian systems with index one constraints. These include the Hamiltonian description of variational problems subject to position and velocity constraints ...

More Toda-like (0,2) mirrors [PDF]

, 2017
In this paper, we extend our previous work to construct (0,2) Toda-like mirrors to A/2-twisted theories on more general spaces, as part of a program of understanding (0,2) mirror symmetry.

Angular Momentum and Mutually Unbiased Bases [PDF]

, 2005
The Lie algebra of the group SU(2) is constructed from two deformed oscillator algebras for which the deformation parameter is a root of unity. This leads to an unusual quantization scheme, the {J2,Ur} scheme, an alternative to the familiar {J2,Jz ...

Exactly solvable Kitaev model in three dimensions [PDF]

, 2009
We introduce a spin-1/2 model in three dimensions which is a generalization of the well-known Kitaev model on a honeycomb lattice. Following Kitaev, we solve the model exactly by mapping it to a theory of non-interacting fermions in the background of a ...

Parton distribution functions and quark orbital motion

, 2007
Covariant version of the quark-parton model is studied. Dependence of the structure functions and parton distributions on the 3D quark intrinsic motion is discussed.

Entropic Heisenberg limits and uncertainty relations from the Holevo information bound [PDF]

, 2018
Strong and general entropic and geometric Heisenberg limits are obtained, for estimates of multiparameter unitary displacements in quantum metrology, such as the estimation of a magnetic field from the induced rotation of a probe state in three ...

The elliptic quantum algebra $U_{q,p}(\hat{sl_N})$ and its vertex operators

, 2009
We construct a realization of the elliptic quantum algebra $U_{q,p}(\hat{sl_N})$ for any given level $k$ in terms of free boson fields and their twisted partners. It can be considered as the elliptic deformation of the Wakimoto realization of the quantum

Algebraic bosonization: the study of the Heisenberg and Calogero-Sutherland models [PDF]

, 1996
We propose an approach to treat (1+1)--dimensional fermionic systems based on the idea of algebraic bosonization. This amounts to decompose the elementary low-lying excitations around the Fermi surface in terms of basic building blocks which carry a ...

Studies on X-ray Thomson Scattering from Antiferroquadrupolar Order in TmTe

, 2010
We study Thomson scattering from the antiferroquadrupole ordering phase in TmTe. On the basis of the group theoretical treatment, we classify the selection rules of the scattering intensity governed by the orientation of the scattering vector G.
