One of the biggest issues in the design of a superconducting magnet is to be able to protect the magnet during an accidental quench. The quench is the transition between the superconducting state and the resistive state of a superconducting magnet, g

Particle accelerators play a central role in the advancement of fundamental physics research. In circular accelerators such as the Large Hadron Collider (LHC) at CERN, the trajectory of the particle beams must be bent with magnetic fields. For this p

Degenerate quantum gases offer an ideal platform to study superfluidity. An annular superfluid has many subtle properties due to its topological geometry. In this manuscript, we present three ring-shaped superfluids, obtained with different formation

In this thesis, we describe a new cryogenic apparatus (called CryoLEM) used to study rotating helium II (or superfluid) flows by visualization of solid deuterium particles. Rotating helium II is a canonical flow that produces an organized and regular

In this work, we transfer a Bose-Einstein condensate of metastable Helium atoms to a 3D cubic lattice potential (optical lattice). This system is an experimental realization of the Bose-Hubbard Hamiltonian that depends on two parameters that are the

The hypothesis starts from considering the physical vacuum as a superfluid quantum medium, that we call superfluid quantum space (SQS), close to the previous concepts of quantum vacuum, quantum foam, superfluid vacuum etc. We usually believe that qua

Dans cette thèse, nous étudions deux aspects de la dynamique d'impuretés atomiques interagissant avec des nanogouttes d'hélium superfluide (He) : la photo-excitation d'alcalins sur une nanogoutte et le dopage de nanogouttes contenant des tourbill

In this thesis we investigate two aspects of the dynamics of atomic impurities interacting with superfluid helium (He) nanodroplets, namely the photo-excitation of alkalis on a nanodroplet and the doping process of nanodroplets hosting quantised vort
