Information and Entropy in Neural Networks and Interacting Systems
... α, β, γ and δ waves can indicate the overall state of alertness of a human being. Artificial neural networks (ANN) may also try to mimic these features, as in many cases it may be more convenient than a simple sequential set of one-time transformations. Short-term memory, in particular is refreshed ...

Sharp Tunneling Peaks in a Parametric Oscillator: Quantum Resonances Missing
... dynamical tunneling [5]. It can be understood for a parametric oscillator, which is excited by modulation at frequency !F close to 2!0 . Classically, a weakly nonlinear oscillator can have two states of vibrations at frequency !F =2, which have the same amplitudes and differ in phase by [6]. Quant ...

Rydberg assisted light shift imbalance induced blockade in an atomic ensemble ,
... When exposed to only a single photon (or in a Raman transition, where one leg is exposed to a single photon), an ensemble of two-level atoms does indeed behave like a single two-level system. This property has been used to realize quantum memory elements using such an ensemble [12,13]. However, any ...

... The resonance lines are found by calculating the transmission through the quantum dot as function of X` and Xr . One then finds [30] that when either X` or Xr is varied while the other parameter is kept fixed, the maxima of the transmission occur on two ‘resonance lines’, shown in thick lines in Fig ...
