Mediated interactions between Fermi polarons and the role of impurity quantum statistics
Cosetta Baroni, Bo Huang, Isabella Fritsche +7
The notion of quasi-particles is essential for understanding the behaviour of complex many-body systems. A prototypical example of a quasi-particle, a polaron, is an impurity stron…
Massive superfluid vortices and vortex necklaces on a planar annulus
Matteo Caldara, Andrea Richaud, Massimo Capone +1
We study a superfluid in a planar annulus hosting vortices with massive cores. An analytical point-vortex model shows that the massive vortices may perform radial oscillations on t…
Dynamics of a massive superfluid vortex in confining potentials
Andrea Richaud, Pietro Massignan, Vittorio Penna +1
We study the motion of a superfluid vortex in condensates having different background density profiles, ranging from parabolic to uniform. The resulting effective point-vortex mode…
Repulsive Fermi and Bose Polarons in Quantum Gases
Francesco Scazza, Matteo Zaccanti, Pietro Massignan +2
Polaron quasiparticles are formed when a mobile impurity is coupled to the elementary excitations of a many-particle background. In the field of ultracold atoms, the study of the a…
Ultra-long quantum walks via spin-orbit photonics
Francesco Di Colandrea, Amin Babazadeh, Alexandre Dauphin +3
The possibility of fine-tuning the couplings between optical modes is a key requirement in photonic circuits for quantum simulations. In these architectures, emulating the long-tim…
Strongly interacting impurities in a dilute Bose condensate
Nikolay Yegovtsev, Pietro Massignan, Victor Gurarie
An impurity in a Bose gas is commonly referred to as Bose polaron. For a dilute Bose gas its properties are expected to be universal, that is dependent only on a few parameters cha…
