Superfluid bosons and flux liquids: disorder, thermal fluctuations, and finite-size effects
The influence of different types of disorder (both uncorrelated and correlated) on the superfluid properties of a weakly interacting or dilute Bose gas, as well as on the corresponding quantities for flux line liquids in ...
Interactions and pinning energies in the Bose glass phase of vortices in superconductors
We study the ground state and low energy excitations of vortices pinned to columnar defects in superconductors, taking into account the long–range interaction between the fluxons. We consider the “underfilled” situation ...
Interferometric Model For Phase Analysis in Fiber Couplers
(Optical Society of America, 1996-07-01)
An interferometric model is proposed to estimate the phase differences in lossless, strongly coupled biconical fiber couplers. This approximate method is simpler than the traditional s-parameter network theory-based analysis ...
Continuous elastic phase transitions and disordered crystals
We review the theory of second–order (ferro–)elastic phase transitions, where the order parameter consists of a certain linear combination of strain tensor components, and the accompanying soft mode is an acoustic phonon. ...
An analysis of nonoblique corrections to the Zb¯b vertex
We present a model–independent analysis of the Zb¯b vertex, with the aim of constraining contributions of new physics to the left- and right–handed couplings of the b. We find that the left–handed coupling of the b is quite ...
