Effect of channel block on the spiking activity of excitable membranes in a stochastic Hodgkin-Huxley model [PDF]
, 2004 The influence of intrinsic channel noise on the spontaneous spiking activity of poisoned excitable membrane patches is studied by use of a stochastic generalization of the Hodgkin-Huxley model.

Spontaneous Generation of Magnetic Field in Three Dimensional QED at Finite Temperature [PDF]
, 1997 We investigate the effects of thermal fluctuations on the spontaneous magnetic condensate in three dimensional QED coupled with P-odd Dirac fermions. Our results show that the phenomenon of the spontaneous generation of the constant background magnetic ...

Advances in nonlinear metasurfaces for imaging, quantum, and sensing applications
Nanophotonics, 2023 Metasurfaces, composed of artificial meta-atoms of subwavelength size, can support strong light–matter interaction based on multipolar resonances and plasmonics, hence offering the great capability of empowering nonlinear generation.

Spontaneous Generation of Photons in Transmission of Quantum Fields in PT Symmetric Optical Systems
, 2013 We develop a rigorous mathematically consistent description of PT symmetric optical systems by using second quantization. We demonstrate the possibility of significant spontaneous generation of photons in PT symmetric systems.
