A Formalism Useful to Study Beyond Squeezing in Non-linear Quantum Optics
Noriaki Aibara, Naoaki Fujimoto, So Katagiri +3
A general formalism is given in quantum optics within a ring cavity, in which a non-linear material is stored. The method is Feynman graphical one, expressing the transition amplit…
Surround Inhibition Mechanism by Deep Learning
Naoaki Fujimoto, Muneharu Onoue, Akio Sugamoto +2
In the sensation of tones, visions and other stimuli, the "surround inhibition mechanism" (or "lateral inhibition mechanism") is crucial. The mechanism enhances the signals of the…
Beyond Squeezing à la Virasoro Algebra
So Katagiri, Akio Sugamoto, Koichiro Yamaguchi +1
The generalization of squeezing is realized in terms of the Virasoro algebra. The higher-order squeezing can be introduced through the higher-order time-dependent potential, in whi…
Quantum-classical correspondence via coherent state in integrable field theory
Jun Sato, Tsukasa Yumibayashi
We consider the problem of quantum-classical correspondence in integrable field theories. We propose a method to construct a field theoretical coherent state, in which the expectat…
Gravity Analog Model of Non-equilibrium Thermodynamics
Noriaki Aibara, Naoaki Fujimoto, So Katagiri +4
Non-equilibrium thermodynamics of Onsager and Machlup and of Hashitsume is reformulated as a gravity analog model, in which thermodynamic variables, kinetic coefficients and genera…
Time dependent Pais-Uhlenbeck oscillator and its decomposition
H. Kuwabara, T. Yumibayashi, H. Harada
The Pais-Uhlenbeck(PU) oscillator is the simplest model with higher time derivatives. Its properties were studied for a long time. In this paper, we extend the 4th order free PU os…
