For the gauge couplings, which arise after toroidal compactification of six–dimensional heterotic N=1 string theories from the T 2 torus, we calculate their one–loop corrections. This is performed by considering string amplitudes involving two gauge fields and moduli fields. We compare our results with the equations following from N=2 special geometry and the underlying prepotential of the theo...

We report the strong dependence of resistance on uniaxial strain in monolayer WSe2 at various temperatures, where gauge factor can reach as large 2400. The observation strain-dependent and giant is attributed to emergence nonzero Berry curvature dipole. Upon increasing strain, dipole generate net orbital magnetization, which would introduce additional magnetic scattering, decreasing mobility th...

Gauge fixing is a frequent task encountered in practical lattice gauge theory calculations. We review the performance characteristics of some standard gauging procedures for non-Abelian gauge theories, implemented on the parallel machines CM2 and CM5. †

We investigate critical properties of the phase transition in the four-dimensional compact U(1) lattice gauge theory supplemented by a monopole term for values of the monopole coupling λ such that the transition is of second order. It has been previously shown that at λ = 0.9 the critical exponent is already characteristic of a second-order transition and that it is different from the one of th...

The calculation of QCD corrections to the width difference ∆Γ in the Bs-meson system is presented. The next-to-leading order corrections reduce the dependence on the renormalization scale significantly and allow for a meaningful use of hadronic matrix elements from lattice gauge theory. At present the uncertainty of the lattice calculations limits the prediction of ∆Γ. The presented work has be...

We discuss the question of what type and scale of supersymmetry breaking might be statistically favored among vacua of string/M theory, building on comments in Denef and Douglas, hep-th/0404116.
