Photon-photon interactions in cavity electromagnetically induced transparency [PDF]

Physical Review A, 1999
Dissipation-free photon-photon interaction at the single photon level is studied in the context of cavity electromagnetically induced transparency (EIT). For a single multilevel atom exhibiting EIT in the strong cavity-coupling regime, the anharmonicity of the atom-cavity system has an upper bound determined by single atom-photon coupling strength ...

Explicit Solution of the Time Domain Volume Integral Equation Using a Stable Predictor-Corrector Scheme [PDF]

, 2012
An explicit marching-on-in-time (MOT) scheme for solving the time domain volume integral equation is presented. The proposed method achieves its stability by employing, at each time step, a corrector scheme, which updates/corrects fields computed by the ...

Real-time 3D temperature reconstruction in microwave cancer hyperthermia from scarce temperature measurements

Nature Communications
Oncological microwave hyperthermia is a clinically proven sensitizer of radio- and chemo-therapies; it acts by selectively increasing the temperature of tumor cells by means of antenna applicators.

Dynamic electromagnetic polarizabilities of the photon

Physics Letters B, 1976
Abstract The dynamic electric and magnetic polarizabilities of the photon α and β are calculated by means of a backward dispersion relation for the relevant Compton amplitude. It is pointed out that the annihilation channel exchanges could be responsible for the ordering α > β given by the present experimental determinations.

Electromagnetic and gravitational responses of photonic Landau levels [PDF]

Nature, 2019
Topology has recently become a focus in condensed matter physics, arising in the context of the quantum Hall effect and topological insulators. In both of these cases, the topology of the system is defined through bulk properties ('topological invariants') but detected through surface properties.
