On relation between renormalized frequency and heat capacity for particles in an anharmonic potential
Y. T. Liu, Y. H. Zhao, Y. Zhong +3
For free particles in a simple harmonic potential plus a weak anharmonicity, characterized by a set of anharmonic parameters, Newtonian mechanics asserts that there is a renormaliz…
A correspondence from renormalized frequency to heat capacity for particles in an anharmonic potential
Y. T. Liu, Y. H. Zhao, Y. Zhong +2
For particles in an anharmonic potential, classical mechanics asserts that there is a renormalization of the bare frequency of the oscillatory motion, and statistical mechanics cla…
Perturbative Approach to the Quasinormal Modes of Dirty Black Holes
P. T. Leung, Y. T. Liu, W. -M. Suen +2
Using a recently developed perturbation theory for uasinormal modes (QNM's), we evaluate the shifts in the real and imaginary parts of the QNM frequencies due to a quasi-static per…
Logarithmic perturbation theory for quasinormal modes
P. T. Leung, Y. T. Liu, W. M. Suen +2
Logarithmic perturbation theory (LPT) is developed and applied to quasinormal modes (QNMs) in open systems. QNMs often do not form a complete set, so LPT is especially convenient b…
