Johnson-Nyquist noise fluctuation-dissipation energy-harvesting quantum heat engines
2010/10/27
Electrical heat engines driven by the Johnson-Nyquist noise of resistors are introduced.
They utilize Coulomb's law and the fluctuation-dissipation theorem of statistical physics that is the reverse ...
On the effect of multiplicative noise in a supercritical pitchfork bifurcation
multiplicative noise supercritical pitchfork bifurcation
2010/4/21
The most important characteristic of {\em multiplicative noise} is that its effects of system's dynamics depends on the recent system's state. Consideration of multiplicative noise on self-referential...
Effective phase dynamics of noise-induced oscillations in excitable systems
phase dynamics noise-induced oscillations excitable systems
2010/4/1
We develop an effective description of noise-induced oscillations based on deterministic phase dynamics. The phase equation is constructed to exhibit correct frequency and distribution density of nois...
Noise resilient quantum interface based on QND interaction
quantum interface Noise resilient quantum-non-demolition interactions
2010/3/10
We propose a quantum interface protocol based on two quantum-non-demolition interactions (QND) arranged either in sequence or in parallel. Since the QND coupling arises naturally in interactions betwe...
Quantum noise and self-sustained radiation of PT-symmetric systems
Quantum noise self-sustained radiation PT-symmetric systems
2010/3/10
The observation that PT-symmetric Hamiltonians can have real-valued energy levels even if they are non-hermitian has triggered intense activities, with experiments in particular focusing on optical sy...
Extracting strong measurement noise from stochastic series: applications to empirical data
stochastic series noise empirical data
2010/4/6
It is a big challenge in the analysis of experimental data to disentangle the unavoidable measurement noise from the intrinsic dynamical noise. Here we present a general operational method to extract ...
Capacities of lossy bosonic channel with correlated noise
lossy bosonic channel correlated noise
2010/4/12
We evaluate the information capacities of a lossy bosonic channel with correlated noise. The model generalizes the one recently discussed in [Phys. Rev. A 77, 052324 (2008)], where memory effects come...
Dynamical properties of a mutualism system in the presence of noise and time delay
time delay relaxation time correlation function mutualism system
2010/7/5
The normalized correlation function C(s) and the associated relaxation time Tc of the mutualism system in the presence of noise and time delay are investigated. The effects of noise and time delay on ...
Highly efficient energy excitation transfer in light-harvesting complexes: The fundamental role of noise-assisted transport
energy excitation light-harvesting complexes undamental role of noise-assisted transport
2010/4/9
Excitation transfer through interacting systems plays an important role in many areas of physics, chemistry, and biology. The uncontrollable interaction of the transmission network with a noisy enviro...
Noise effects in a three-player Prisoner's Dilemma quantum game
Prisoner＇s Dilemma Three-player Decoherenc Correlated Noise Dephasing Channel
2010/4/8
We study the three-player Prisoner's Dilemma game under the effect of decoherence and correlated noise. It is seen that the quantum player is always better off over the classical players. It is also s...
Non-commuting noises may give rise to entanglement sudden death. By considering the decoherence dynamics during establishment of the channel states and noisy recovery operations, we study further the ...
