The Kondo Temperature of SU(4) Symmetric Quantum Dots

, 2014
A path integral approach is used to derive a closed analytical expression for the Kondo temperature of the SU(4) symmetrical Anderson model. In contrast to the SU(2) case, the prefactor of the Kondo temperature is found to display a peculiar orbital ...

Comment on “Kinetic decoupling of WIMPs: Analytic expressions”

Physical Review D, 2017
Visinelli and Gondolo [Phys. Rev. D 91, 083526 (2015).PRVDAQ1550-799810.1103/PhysRevD.91.083526, hereafter VG15] derived analytic expressions for the evolution of the dark matter temperature in a generic cosmological model. They then calculated the dark matter kinetic decoupling temperature Tkd and compared their results to the Gelmini and Gondolo [J ...

Analytic expression for the pull-or-jerk experiment [PDF]

European Journal of Physics, 2014
This work focuses on a theoretical analysis of a well-known inertia demonstration, which uses a weight suspended by a string with an extra string that hangs below the weight. The point in question is which string, the upper or lower, will break when pulling down on the bottom edge of the lower string at a constant pulling speed.

Spurious diffusion in particle simulations of the Kolmogorov flow

, 2001
Particle simulations of the Kolmogorov flow are analyzed by the Landau-Lifshitz fluctuating hydrodynamics. It is shown that a spurious diffusion of the center of mass corrupts the statistical properties of the flow.

Cumulative beam breakup due to resistive-wall wake

Physical Review Special Topics. Accelerators and Beams, 2004
The cumulative beam breakup problem excited by the resistive-wall wake is formulated. An approximate analytic method of finding the asymptotic behavior for the transverse bunch displacement is developed and solved.
