On the tensor reduction of one-loop pentagons and hexagons
T. Diakonidis, J. Fleischer, J. Gluza +3
We perform analytical reductions of one-loop tensor integrals with 5 and 6 legs to scalar master integrals. They are based on the use of recurrence relations connecting integrals i…
A singular perturbation approach to the steady-state 1D Poisson-Nernst-Planck modeling
I. D. Kosińska, I. Goychuk, M. Kostur +2
The reduced 1D Poisson-Nernst-Planck (PNP) model of artificial nanopores in the presence of a permanent charge on the channel wall is studied. More specifically, we consider the li…
A weak acceleration effect due to residual gravity in a multiply connected universe
Boudewijn F. Roukema, Stanislaw Bajtlik, Marek Biesiada +2
Could cosmic topology imply dark energy? We use a weak field (Newtonian) approximation of gravity and consider the gravitational effect from distant, multiple copies of a large, co…
Universal scaling and quantum critical behavior of CeRhSb(1-x)Sn(x)
A. Slebarski, J. Spalek
We propose a universal scaling rho*chi=const of the electrical resistivity rho with the inverse magnetic susceptibility chi^(-1) below the temperature of the quantum-coherence onse…
Numerical evaluation of master integrals from differential equations
M. Caffo, H. Czyz, E. Remiddi
The 4-th order Runge-Kutta method in the complex plane is proposed for numerically advancing the solutions of a system of first order differential equations in one external invaria…
Numerical evaluation of the general massive 2-loop self-mass master integrals from differential equations
M. Caffo, H. Czyz, E. Remiddi
The system of 4 differential equations in the external invariant satisfied by the 4 master integrals of the general massive 2-loop sunrise self-mass diagram is solved by the Runge-…
