Dissipationless Electron Transport in Photon-Dressed Nanostructures [PDF]
Physical Review Letters, 2011 It is shown that the electron coupling to photons in field-dressed nanostructures can result in the ground electron-photon state with a nonzero electric current. Since the current is associated with the ground state, it flows without the Joule heating of the nanostructure and is nondissipative.

Scattering theory of photon-assisted electron transport [PDF]
Physical Review B, 1998 The scattering matrix approach to phase-coherent transport is generalized to nonlinear ac-transport. In photon-assisted electron transport it is often only the dc-component of the current that is of experimental interest. But ac-currents at all frequencies exist independently of whether they are measured or not.

Manifestation of the Purcell Effect in Current Transport through a Dot–Cavity–QED System
Nanomaterials, 2019 We study the transport properties of a wire-dot system coupled to a cavity and a photon reservoir. The system is considered to be microstructured from a two-dimensional electron gas in a GaAs heterostructure.

Beilstein Journal of Nanotechnology, 2019 In this work, we theoretically model the time-dependent transport through an asymmetric double quantum dot etched in a two-dimensional wire embedded in a far-infrared (FIR) photon cavity.

Chirality dependent photon transport and helical superradiance
Physical Review ResearchChirality, or handedness, is a geometrical property denoting a lack of mirror symmetry. Chirality is ubiquitous in nature and is associated with the nonreciprocal interactions observed in complex systems ranging from biomolecules to topological materials.

Thermoelectric Inversion in a Resonant Quantum Dot-Cavity System in the Steady-State Regime
Nanomaterials, 2019 We theoretically investigate thermoelectric effects in a quantum dot system under the influence of a linearly polarized photon field confined to a 3D cavity.

Annals of Physics, 1961 Abstract A first order, momentum-configuration space transport equation for photons is derived for low energy (nonrelativistic) systems. The derivation is first order in the sense that the transition probabilities characterizing photon scattering emission and absorption are computed only to the first nonvanishing order by conventional perturbation ...

Quantum Beam Science, 2022 The emission of characteristic lines after X-ray excitation is usually explained as the consequence of two independent and consecutive physical processes: the photoelectric ionization produced by incoming photons and the successive spontaneous atomic ...

On model-based hyperspectral imaging
Current Directions in Biomedical Engineering, 2022 Several contributions are presented to aid the analysis of hyperspectral images by utilizing appropriate optical models. The algorithms are described by means of the perfusion of human skin and a corresponding two-layer tissue model.
