Discovery of slow X-ray pulsations in the high-mass X-ray binary 4U 2206+54
P. Reig, J. M Torrejon, I. Negueruela +3
The source 4U 2206+54 is one of the most enigmatic high-mass X-ray binaries. In spite of intensive searches, X-ray pulsations have not been detected in the time range 0.001-1000 s.…
Transmission thresholds in time-periodically driven nonlinear disordered systems
Magnus Johansson, Georgios Kopidakis, Stefano Lepri +1
We study energy propagation in locally time-periodically driven disordered nonlinear chains. For frequencies inside the band of linear Anderson modes, three different regimes are o…
Free Fermion Orientifolds
Elias Kiritsis, Michael Lennek, Bert Schellekens
We investigate a class of orientifold models based on tensor products of 18 Ising models. Using the same search criteria as for the comparable case of Gepner model orientifolds we…
Picosecond laser structuration under high pressures: observation of boron nitride nanorods
Luc Museur, Jean Pierre Petitet, Jean Pierre Michel +4
We report on picosecond UV-laser processing of hexagonal boron nitride (hBN) at moderately high pressures above 500 bar. The main effect is specific to the ambient gas and laser pu…
Optical Anisotropy of Electronic Excitations in Elliptical Quantum Dots
Achintya Singha, Vittorio Pellegrini, Sokratis Kalliakos +4
The authors report that anisotropic confining potentials in laterally-coupled semiconductor quantum dots (QDs) have large impacts in optical transitions and energies of inter-shell…
Algorithms for translational tiling
Mihail N. Kolountzakis, Mate Matolcsi
In this paper we study algorithms for tiling problems. We show that the conditions and of Coven and Meyerowitz, conjectured to be necessary and sufficient for a finit…
