Möbius strip microlasers: Quantum chaos on curved surfaces

Möbius strip microlasers are fabricated by direct laser writing. Experiments and 3D FDTD numerical simulations evidence that laser modes propagate along periodic geodesics, a geodesic being the shortest path between two points on a surface.

Spin-noise spectroscopy of a spin-one system

The spin-noise mechanisms in a spin-1 system are theoretically and experimentally investigated in detail. Eight different independent spin degrees of freedom are isolated, leading to spin-noise signals at the Larmor frequency or its second harmonic…

Spin-noise spectroscopy of optical light shifts

Light-induced nonequilibrium spin-noise spectroscopy is theoretically and experimentally shown to be an efficient technique to reveal the structure and coherent effects in a probed transition. Indeed, using metastable helium, the spin-noise spectrum…

DM1 transgenic mice exhibit abnormal neurotransmitter homeostasis and synaptic plasticity in association with RNA mis-splicing in the hippocampus.

Myotonic dystrophy type 1 (DM1) is a severe neuromuscular disease mediated by a toxic gain of function of mutant RNAs. The neuropsychological manifestations affect multiple domains of cognition and behaviour, but their aetiology remains elusive…

Behaviour of Square and Rectangular Tunnels Using an Improved Finite Element Method

Due to its advantages (fast and accurate calculations), the Hyperstatic Reaction Method (HRM) was used to calculate the internal forces of circular tunnel linings in former works. This paper presents an improved HRM method that is developed to…
