TL;DR: Cooper pairs impinging stochastically at a mesoscopic beamsplitter have been successfully partitioned, as verified by measuring the coincidence of arrival, which opens a path to future on-demand generation of spin-entangled electron pairs from a suitably prepared two-electron quantum-dot ground state.

TL;DR: The conclusions established in this study can be extended to a variety of transition metal trichalcogenide materials as well as other quasi-1D crystals, and the possibility of exfoliation of TiS3 into narrow crystals with smooth edges could be important for the future realization of miniature device channels with reduced edge scattering of charge carriers.

TL;DR: The application of scattering-type near-field optical microscopy to characterize various semiconducting materials using the electron storage ring Metrology Light Source (MLS) as a broadband synchrotron radiation source shows high sensitivity for spectroscopic material discrimination.

TL;DR: The results reveal the capability of the s-SNOM technique to study local multiple excitations in complex non-homogeneous structures and reveal the plasmonic character of the MoS( 2) structures and their interaction with the SiO(2) phonons leading to an enhancement of the hybridized surface plasMon-phonon mode.

TL;DR: The influence of the properties of the radiation source, such as the electron bunch shape and spectral bandwidth of the emitted radiation, on near-field infrared spectra of silicon-carbide (SiC) is investigated to exploit the full potential of nano-FTIR spectroscopy.
