Lessons learned after three years of SPIDER operation and the first MITICA integrated tests
D. Marcuzzi, V. Toigo, M. Boldrin +139
ITER envisages the use of two heating neutral beam injectors plus an optional one as part of the auxiliary heating and current drive system. The 16.5 MW expected neutral beam power…
Analogue quantum simulation of the Hawking effect in a polariton superfluid
Maxime J. Jacquet, Malo Joly, Luca Giacomelli +5
Quantum effects of fields on curved spacetimes may be studied in the laboratory thanks to quantum fluids. Here we use a polariton fluid to study the Hawking effect, the correlated…
Interplay of Kelvin-Helmholtz and superradiant instabilities of an array of quantized vortices in a two-dimensional Bose--Einstein condensate
Luca Giacomelli, Iacopo Carusotto
We investigate the various physical mechanisms that underlie the dynamical instability of a quantized vortex array at the interface between two counter-propagating superflows in a…
Spontaneous quantum superradiant emission in atomic Bose-Einstein condensates subject to a synthetic vector potential
Luca Giacomelli, Iacopo Carusotto
We theoretically investigate the spontaneous quantum emission of phonon pairs by superradiant processes in an atomic Bose-Einstein condensate subject to a synthetic vector potentia…
Understanding superradiant phenomena with synthetic vector potentials in atomic Bose-Einstein condensates
Luca Giacomelli, Iacopo Carusotto
We theoretically investigate superradiance effects in quantum field theories in curved space-times by proposing an analogue model based on Bose--Einstein condensates subject to a s…
Ergoregion instabilities in rotating two-dimensional Bose--Einstein condensates: new perspectives on the stability of quantized vortices
Luca Giacomelli, Iacopo Carusotto
We investigate the stability of vortices in two-dimensional Bose--Einstein condensates. In analogy with rotating spacetimes and with a careful account of boundary conditions, we sh…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…

Rotating black hole solutions in relativistic analogue gravity
Luca Giacomelli, Stefano Liberati
Simulation and experimental realization of acoustic black holes in analogue gravity systems have lead to a novel understanding of relevant phenomena such as Hawking radiation or su…
Characterization of Monoenergetic Neutron Reference Fields with a High Resolution Diamond Detector
A. Zimbal, L. Giacomelli, R. Nolte +1
A novel radiation detector based on an artificial single crystal diamond was used to characterize in detail the energy distribution of neutron reference fields at the Physikalisch-…
