We present a microscopic theory of nonlinear damping and dephasing of low-frequency
eigenmodes in nanomechanical and micromechanical systems. The mechanism of the both …

Molecular relaxation in the KNO3–Na2SO4, NaNO3–Na2SO4 and NaNO3–NaCH3COO

The power spectrum of the archetypal fluctuating bistable system, the underdamped double-
well Duffing oscillator, is investigated both experimentally, with use of an electronic circuit …

It is presented the Raman and infrared (IR) spectroscopic investigations of the thiocyanates:
LiSCN, NaSCN, KSCN, RbSCN, CsSCN; nitrates: Ca (NO3) 2, Sr (NO3) 2, Ba (NO3) 2, Pb …

The spectral distribution Q (ω) of the coordinate fluctuations is studied for an oscillator
performing Brownian motion in a double-well potential at low damping. The most detailed …

Experimental and theoretical studies of electron transport in low-mobility and some
disordered semiconductors have attracted increasing interest during the last decade. The …

Fluctuations of a nonlinear oscillator driven by an intense resonant field with fluctuating
phase are considered in the region of bistability. The general expression for the probability …
