Asymptotic formula for the condensate wave function of a trapped Bose gas
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
2012/6/15
Einstein's relation E=Mc^2 between the energy E and the mass M is the cornerstone of the relativity theory. This relation is often derived in a context of the relativistic theory for closed systems wh...
Efficient computation of the Zassenhaus formula
Efficient computation Zassenhaus formula 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
The six-vertex model Open spin chain Partition function
2011/9/22
Abstract: With the help of the F-basis provided by the Drinfeld twist or factorizing F-matrix for the open XXZ spin chain with non-diagonal boundary terms, we obtain the determinant representation of ...
On the determinant formula in the inverse scattering procedure with a partially known steplike potential
Marchenko inverse scattering Schrodinger operator Titchmarsh-Weyl m− function
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...
Deformation Expression for Elements of Algebras (III) --Generic product formula for *-exponentials of quadratic forms--
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...
Generalized local Taylors formula with local fractional derivative

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...
Matrix Model and Refined Wall-Crossing Formula
Matrix Model Refined Wall-Crossing Formula
2010/12/23
In this paper, we show how to get matrix models corresponding to the refined BPS states partition functions of $\mathbb{C}^3$, resolved conifold and $\mathbb{C}^3/\mathbb{Z}_2$ by inserting the ident...
Quantum mechanical photon-count formula derived by entangled state
Quantum mechanical photon-count formula derived entangled state
2010/11/9
By introducing the thermo entangled state representation, we derived four new photocount distribution formulas for a given density operator of light field. It is shown that these new formulas, which ...
A periodic orbit formula for quantum reactions through transition states
periodic orbit formula quantum reactions transition states
2010/4/1
Transition State Theory forms the basis of computing reaction rates in chemical and other systems. Recently it has been shown how transition state theory can rigorously be realized in phase space usin...
Application of Abel-Plana formula for collapse and revival of Rabi oscillations in Jaynes-Cummings model
Application of Abel-Plana formula collapse and revival Rabi oscillations JaynesCummings model
2010/4/9
In this paper, we give an analytical treatment to study the behaviour of the collapse and the revival of the Rabi oscillations in the Jaynes-Cummings model (JCM). The JCM is an exactly soluble quantum...
