Quantum manifestations of classical nonlinear resonances
(American Physical Society, 2015-12)
When an integrable classical system is perturbed, nonlinear resonances are born, grow, and eventually disappear due to chaos. In this paper the quantum manifestations of such a transition are studied in the standard map. ...
Differential contribution of the subthreshold operating currents IT, Ih, and IKirto the resonance of thalamocortical neurons
(American Physiological Society, 2021-08)
Membrane potential oscillations of thalamocortical (TC) neurons are believed to be involved in the generation and maintenance of brain rhythms that underlie global physiological and pathological brain states. These membrane ...
Internal resonance in a vibrating beam: A zoo of nonlinear resonance peaks
(Public Library of Science, 2016-09-20)
In oscillating mechanical systems, nonlinearity is responsible for the departure from proportionality between the forces that sustain their motion and the resulting vibration amplitude. Such effect may have both beneficial ...
Schumann's resonances: A particular example of a spherical resonant cavity
(American Association of Physics Teachers, 2004-05)
The resonances between the Earth as one boundary and the ionosphere as the other, known as Schumann's resonances, represent an interesting example of a spherical cavity. We consider a simple model in which the boundaries ...
Effects of noise on the internal resonance of a nonlinear oscillator
(Nature Publishing Group, 2018-12)
We numerically analyze the response to noise of a system formed by two coupled mechanical oscillators, one of them having Duffing and van der Pol nonlinearities, and being excited by a self-sustaining force proportional ...
Zero-energy resonance effects in atomic processes within a plasma environment
(IOP Publishing, 2016-11)
We investigate the emergence of zero-energy resonance effects in atomic processes occurring within a plasma. By applying the final-state interaction theory we uncover the presence of these effects for particular configurations ...
Entropy, fidelity, and double orthogonality for resonance states in two-electron quantum dots
(American Physical Society, 2010-04)
Resonance states of a two-electron quantum dots are studied using a variational expansion with both real basis-set functions and complex scaling methods. The two-electron entanglement (linear entropy) is calculated as a ...
Noise reduction in resonator-based ultrasound sensors by using a CW laser and phase detection
(Optical Society of America, 2019-06)
The detection of ultrasound via optical resonators is conventionally performed by tuning a continuous-wave (CW) laser to the linear slope of the resonance and monitoring the intensity modulation at the resonator output. ...
Subharmonic stochastic synchronization and resonance in a neuronal system
(American Physical Society, 2002-10)
We study the response of a model neuron, driven simultaneously by noise and at least two weak periodic signals. We focus on signals with frequencies components kf0,(k+1)f0,…(k+n)f0 with k>1. The neuron’s output is a sequence ...
Resonance switching in a large sonic crystal cavity
(Elsevier, 2017-01)
In this work we present an experimental realization of resonance switching inside a large, relative to the lattice constant, sonic crystal (SC) cavity. The resonances arise from a temporary trapping of the acoustical energy ...
