Can quantum Rabi model with A^2-term avoid no-go theorem for spontaneous SUSY breaking?

Masao Hirokawa

The hierarchy problem asks why the mass of the Higgs particle is so much lighter than the Planck-scale mass. Considering the interaction of the Higgs particle and an elementary par…

A Model without Higgs Potential for Quantum Simulation of Radiative Mass-Enhancement in SUSY Breaking

Masao Hirokawa

We study a quantum-simulation model of a mass enhancement in the fermionic states, as well as in the bosonic ones, of the supersymmetric quantum mechanics. The bosonic and fermioni…

Concealing-Restoring System for Physical Layer Data Based on Stochastic Filtering Theory

Tomohiro Fujii, Masao Hirokawa

We propose a concealing-restoring system (CRS) for data on physical layer of the OSI reference model. CRS conceals those data by disturbing them with some random noises, and restor…

Schrodinger-Cat-Likeness in Adiabatic Approximation for Generalized Quantum Rabi Model without and with A^2-Term

Masao Hirokawa

We give a mathematical procedure to obtain the adiabatic approximation for the generalized quantum Rabi Hamiltonian both without and with a quadratic interaction. We consider the H…

A Mathematical Analysis of Dressed Photon in Ground State of Generalized Quantum Rabi Model Using Pair Theory

Masao Hirokawa, Jacob Schach Moller, Itaru Sasaki

We consider the generalized quantum Rabi model with the so-called -term in the light of the Hepp-Lieb-Preparata quantum phase transition. We investigate the dressed photon i…

A duality between a dark state and a quasi-dark state

Masao Hirokawa

We consider the optomechanical system consisting of an atom-cavity system coupled with a mechanical resonator, and expand the notion of quasi-dark state to the optomechanical syste…
