Operator-frame geometry of non-compact quantum systems with frame-vacuum phase transitions
Satoshi Tanaka, Gonzalo Ordonez, Masatoshi Kubota +2
We formulate the geometric structure of non-compact bosonic quantum systems in regimes where vacuum instability renders the relevant quantum states non-normalizable, causing conven…
Theory of Stationary Photon Emission from a Steadily Driven Parametric Oscillator Based on the Complex Spectral Analysis of the Heisenberg Equation
Kazuki Kanki, Satoshi Tanaka
We show how the properties of photon emission to a continuous field from a parametric oscillator relate to the behavior of the complex eigenfrequencies of the oscillator. The param…
Energy-Efficient Pseudo-Ratchet for Brownian Computers through One-Dimensional Quantum Brownian Motion
Sho Nakade, Ferdinand Peper, Kazuki Kanki +1
Brownian computers utilize thermal fluctuations as a resource for computation and hold promise for achieving ultra-low-energy computations. However, the lack of a statistical direc…
Coherent single-spin electron resonance spectroscopy manifested at an exceptional-point singularity in a doped polyacetylene
Yujin Dunham, Kazuki Kanki, Savannah Garmon +2
Spin-dependent charge transfer decay in an alkali atom doped polyacetylene is studied in terms of the complex spectral analysis, revealing the single-spin Zeeman splitting influenc…
Dissipative dynamical Casimir effect in terms of the complex spectral analysis in the symplectic-Floquet space
Satoshi Tanaka, Kazuki Kanki
Dynamical Casimir effect of the optomechanical cavity interacting with one-dimensional photonic crystal is theoretically investigated in terms of the complex spectral analysis of F…
Anomalous diffusion in Davydov quantum molecular chain model
Sho Nakade, Kazuki Kanki, Satoshi Tanaka +1
We discuss anomalous relaxation processes in Davydov one-dimensional chain molecule that consists of an exciton and an acoustic phonon field as a thermal reservoir in the chain. We…
