In order to detect the small distance variations induced by gravitational waves, very sensitive devices must be used. Gravitational wave (GW) detectors are sophisticated interferometers sensitive even to vacuum fluctuations. These latters are responsible for quantum noise (QN). Due to the frequency-dependent response of GW interferometers, QN manifests itself as Radiation Pressure Noise (RPN)...

Non-neutral plasmas – in the zero temperature limit - can be described in analogy to a $2$-dimensional fluid [1]. We observe the temporal stages of a Kelvin-Helmholtz-like diocotron instability of an antiproton ring. The evolutionary stages are comprised of a linear part during which the instability grows, followed by a collapse of the ring into vortices, and a nonlinear part consisting of...

A jet is a group of collimated high energy particles. Its production in high energy collisions has been used to study the QCD evolution in vacuum. The evolution is modified in heavy ion collisions because of the existence of quark-gluon plasma (QGP). Jets are produced early in the initial hard scattering. As the produced quarks and gluons of the jets travel through the QGP, they lose energy...
