Supersymmetric partner chirping of Newtonian free damping
(1998)
We connect the classical free-damping cases by means of Rosner's construction in supersymmetric quantum mechanics. Starting with the critical damping, one can obtain in the underdamping case a chirping of instantaneous ...

Medida da elasticidade entrópica de uma molécula de DNA
(Universidade Federal de Minas GeraisUFMG, 2001-03-13)
In this work we combine optical tweezer and videomicroscopy techniques to obtain the entropic elastic behavior of single ¸ phage DNA molecules. By tethering a single DNA molecule by one end to a 3¹m poliestirene bead and ...
Exact and approximate analytical solutions of oscillator with piecewise linear asymmetrical damping
(2019-04-01)
The objective of this work is to present exact and approximate analytical solutions of a 1-DOF oscillator with asymmetrical damping under harmonic excitation, and to explore the role of asymmetrical damping in the response ...
State-dependent diffusion in a bistable potential: Conditional probabilities and escape rates
(Amer Physical Soc, 2020-06-02)
We consider a simple model of a bistable system under the influence of multiplicative noise. We provide a path integral representation of the overdamped Langevin dynamics and compute conditional probabilities and escape ...

Macroscopic quantum tunneling in a dc SQUID: Instanton splitting
(1994-12-01)
The theory of macroscopic quantum tunneling is applied to a current-biased dc SQUID which constitutes a system of two interacting quantum degrees of freedom coupled to the environment. The decay probability is obtained in ...
