The low-lying levels of the GR 1 centre in diamond
Abstract The structure of the satellite lines of the GR 1 band in diamond is analysed. It is shown to arise from a vibronic splitting, as in the model of Lannoo and Stoneham. Sufficient data are available to extract values of the Jahn-Teller energy, ...

Classically-controlled Quantum Computation
Abstract It is reasonable to assume that quantum computations take place under the control of the classical world. For modelling this standard situation, we introduce a Classically-controlled Quantum Turing Machine (CQTM) which is a Turing machine...

The role of spin–orbit potential in nuclear prolate-shape dominance
Abstract It is confirmed, in terms of the Woods–Saxon–Strutinsky method, that the spin–orbit potential plays a decisive role in the predominance of prolate deformation, which has been a long standing problem in nuclear physics. It is originated from ...

Split-SUSY dark matter in light of direct detection limits
Abstract We examine the present and future XENON limits on the neutralino dark matter in split supersymmetry (split-SUSY). Through a scan over the parameter space under the current constraints from collider experiments and the WMAP measurement of...

No-go theorems for R symmetries in four-dimensional GUTs
Abstract We prove that it is impossible to construct a grand unified model, based on a simple gauge group, in four dimensions that leads to the exact MSSM, nor to a singlet extension, and possesses an unbroken R symmetry. This implies that no MSSM...

Knots and Links in Fluid Mechanics
Abstract In this paper we will review some questions of current interest in fluid mechanics, addressing various geometric aspects of the vortex lines of the fluid. We wil focus on the study of knotted and linked vortex lines, a topic that can be...

L’Hospital rule for matrix functions
Abstract In this paper, the L’Hospital rule for evaluating limits of complex matrix functions is introduced. We present some specific examples on certain matrix functions showing the applicability of our approach.

A flavor sector for the composite Higgs
Abstract We discuss flavor violation in large N Composite Higgs models. We focus on scenarios in which the masses of the Standard Model fermions are controlled by hierarchical mixing parameters, as in models of Partial Compositeness. We argue that a ...

Double-Disk Dark Matter
Abstract Based on observational tests of large scale structure and constraints on halo structure, dark matter is generally taken to be cold and essentially collisionless. On the other hand, given the large number of particles and forces in the...

Well-mixed dark matter and the Higgs
Abstract The breaking of electroweak symmetry through renormalization group flow in models that have MSSM spectra is found to produce “well-mixed” neutralino dark matter with a relic density consistent with the WMAP data and elastic scattering cross ...
