Germanium Segregation in CVD Grown Sige Layers for Flash Memory Application
Andrei G. Novikau, Peter I. Gaiduk
A 2D layer of spherical, crystalline Ge nanodots embedded in SiO2 was formed by low pressure chemical vapour deposition combined with furnace oxidation and rapid thermal annealing.…
Atomic quantum superposition state generation via optical probing
Anne E. B. Nielsen, Uffe V. Poulsen, Antonio Negretti +1
We analyze the performance of a protocol to prepare an atomic ensemble in a superposition of two macroscopically distinguishable states. The protocol relies on conditional measurem…
On the transition to the normal phase for superconductors surrounded by normal conductors
S. Fournais, A. Kachmar
For a cylindrical superconductor surrounded by a normal material, we discuss transition to the normal phase of stable, locally stable and critical configurations. Associated with t…
Grid Based Linear Neutrino Perturbations in Cosmological N-body Simulations
Jacob Brandbyge, Steen Hannestad
We present a novel, fast and precise method for including the effect of light neutrinos in cosmological N-body simulations. The effect of the neutrino component is included by usin…
Radio Signal by Galactic Dark Matter
Enrico Borriello, Alessandro Cuoco, Gennaro Miele
An interesting strategy for indirect detection of Dark Matter comes through the amounts of electrons and positrons usually emitted by DM pair annihilation. The e+e- gyrating in the…
Efficient multiparticle entanglement via asymmetric Rydberg blockade
M. Saffman, K. Molmer
We present an efficient method for producing particle entangled states using Rydberg blockade interactions. Optical excitation of Rydberg states that interact weakly, yet have…
