Ultra-Strong Light-Matter Coupling Regime with Polariton Dots
Yanko Todorov, Aaron Maxwell Andrews, Raffaele Colombell +5
The regime of ultrastrong light-matter interaction has been investigated theoretically and experimentally, using zero-dimensional electromagnetic resonators coupled with an electro…
Polaritonic spectroscopy of intersubband transitions
Yanko Todorov, Lorenzo Tosetto, Aymeric Delteil +4
We report on an extensive experimental study of intersubband excitations in the THz range arising from the coupling between a quantum well and a zero-dimensional metal-metal microc…
Topological Insulator in the Presence of Spatially Correlated Disorder
A. Girschik, F. Libisch, S. Rotter
We investigate the effect of spatially correlated disorder on two-dimensional topological insulators and on the quantum spin Hall effect which the helical edge states in these syst…
Electron emission from a metal nano-tip by ultrashort laser pulses
G Wachter, C Lemell, J Burgdörfer
We theoretically investigate the interaction of near-infrared few cycle laser pulses of moderate intensity with nano-scale metal tips. Macroscopic field enhancement leads to cohere…
Orbital and spin magnetic moments of transforming 1D iron inside metallic and semiconducting carbon nanotubes
Antonio Briones-Leon, Paola Ayala, Xianjie Liu +6
The orbital and spin magnetic properties of iron inside transforming metallic and semiconducting 1D carbon nanotube hybrids are studied by means of local x-ray magnetic circular di…
Relevance of intra- and inter-subband scattering on the absorption in heterostructures
Camille NDebeka-Bandou, Francesca Carosella, Robson Ferreira +2
We analyze the absorption lineshape for inter-subband transitions in disordered quasi 2D heterostructures by an exact calculation. The intra-subband scatterings control the central…
