LBT/LUCIFER near-infrared spectroscopy of PV Cephei. An outbursting young stellar object with an asymmetric jet
A. Caratti o Garatti, R. Garcia Lopez, G. Weigelt +4
We present a detailed spectroscopic investigation of the young eruptive star PV Cep, to improve our understanding of its nature and characterise its circumstellar environment after…
Continuous-wave coherent imaging with terahertz quantum cascade lasers using electro-optic harmonic sampling
Marco Ravaro, Vishal Jagtap, Giorgio Santarelli +5
We demonstrate a coherent imaging system based on a terahertz (THz) frequency quantum cascade laser (QCL) phase-locked to a near-infrared fs-laser comb. The phase locking enables c…
Ultrahigh Energy Neutrinos at the Pierre Auger Observatory
Pierre Auger Collaboration
The observation of ultrahigh energy (UHE) neutrinos has become a priority in experimental astroparticle physics. UHE neutrinos can be detected with a variety of techniques. In part…
Terahertz quantum cascade lasers with thin resonant-phonon depopulation active regions and surface-plasmon waveguides
M. Salih, P. Dean, A. Valavanis +5
We report three-well, resonant-phonon depopulation terahertz quantum cascade lasers with semi-insulating surface-plasmon waveguides and reduced active region (AR) thicknesses. Devi…
Optical absorption in highly-strained Ge/SiGe quantum wells: the role of Γ-to-Δ scattering
L. Lever, Z. Ikonić, A. Valavanis +7
We report the observation of the quantum-confined Stark effect in Ge/SiGe multiple quantum well heterostructures grown on Si(0.22)Ge(0.78) virtual substrates. The large compressive…
Constructive Zermelo-Fraenkel set theory and the limited principle of omniscience
Michael Rathjen
In recent years the question of whether adding the limited principle of omniscience, LPO, to constructive Zermelo-Fraenkel set theory, CZF, increases its strength has arisen severa…
