Asymptotic formula condensate wave function trapped Bose gas
2015/10/16
An analytical property is pointed out for the universal differential equation first derived by Dalfovo, Pitaevskii, and Stringari for the condensate wave function at the boundary of a trapped Bose gas...
Smarr formula and an extended first law for Lovelock gravity
Static properties lovelock gravitational black holes lovelock theory lovelock coupling
2014/12/18
We study properties of static, asymptotically AdS black holes in Lovelock gravity. Our main result is a Smarr formula that gives the mass in terms of geometrical quantities together with the parameter...
Relativistic point dynamics and Einstein formula as a property of localized solutions of a nonlinear Klein-Gordon equation
Relativistic point dynamics Einstein formula nonlinear Klein-Gordon equation Mathematical Physics

2012/4/18
A new recursive procedure to compute the Zassenhaus formula up to high order is presented, providing each exponent in the factorization directly as a linear combination of independent commutators and ...
Determinant formula for the partition function of the six-vertex model with a non-diagonal reflecting end

2011/9/13
Abstract: We are concerned with the inverse scattering problem for the full line Schr\"odinger operator $-\partial_x^2+q(x)$ with a steplike potential $q$ a priori known on $\Reals_+=(0,\infty)$. Assu...

Weyl algebra Heisenberg Lie algebra meta-plectic groups spinor polar elements
2011/9/5
Abstract: In a noncommutative algebra there is no canonical way to express elements in univalent way, which is often called "ordering problem". In this note we give product formula of the Weyl algebra...

2011/7/26
Abstract: In the present paper, a generalized local Taylor formula with the local fractional derivatives is derived form the local fractional calculus. An application to approximation of Mittag-Leffle...
Generalisation of Gunion-Bertsch Formula for Soft Gluon Emission
Generalisation of Gunion-Bertsch Formula Soft Gluon Emission
2011/6/2
We generalise the most extensively used Gunion-Bertsch formula for the soft gluon emission in
a perturbative QCD. We show that the corrections arising due to this generalisation could be very importa...
