Continuous energy adjoint transport for photons in PHITS

EPJ Web of Conferences, 2017
Adjoint Monte Carlo can be an effcient algorithm for solving photon transport problems where the size of the tally is relatively small compared to the source. Such problems are typical in environmental radioactivity calculations, where natural or fallout

Topological photon pumping in quantum optical systems [PDF]

Quantum
We establish the concept of topological pumping in one-dimensional systems with long-range couplings and apply it to the transport of a photon in quantum optical systems. In our theoretical investigation, we introduce an extended version of the Rice-Mele

Directing near-infrared photon transport with core@shell particles

AIP Advances, 2020
Directing the propagation of near-infrared radiation is a major concern in improving the efficiency of solar cells and thermal insulators. A facile approach to scatter light in the near-infrared region without excessive heating is to embed compact layers

Single-photon pulse transport in a waveguide coupled with a quantum system

Results in Optics, 2020
We study the transmission and reflection properties of a single-photon pulse in a one-dimensional waveguide side coupled with a Jaynes-Cummings system, namely, a multi-cavity with an embedded Rydberg atom.

Tuning nonequilibrium heat current and two-photon statistics via composite qubit-resonator interaction

Physical Review Research, 2022
Quantum thermal transport and two-photon statistics serve as two representative nonequilibrium features in circuit quantum electrodynamics (cQED) systems.

Rabi-resonant and intraband transitions in a multilevel quantum dot system controlled by the cavity-photon reservoir and the electron-photon coupling

Results in Physics, 2019
The transport properties of a wire-dot system coupled to a quantized single photon with linear polarization in a 3D-cavity is theoretically studied using a quantum master equation. The system is also coupled to a photon reservoir, environment.
