Poster Title: “Dynamics of a Chester Supersolid of Interlayer Excitons in Double Layer Systems”
Summary of the presentation: We investigate the time-dependent dynamic of interlayer exciton condensate by solving the full Gross–Pitaevskii equation for a 2D system. We show that the Gross–Pitaevskii equation admits solutions dependent on the electron–hole interlayer separation and density. In the region of phase space with large interlayer distances, we establish the existence of a Chester supersolid ground state with a periodic lattice structure and one exciton per site. We also investigate the formation of vortices, which can be used to experimentally establish the appearance of Bose–Einstein Condensation and the transition from superfluid to supersolid.

Poster Title: “A Josephson Phase Battery”
Summary of the presentation: The study discusses the development of a phase battery, a quantum device that provides a constant phase bias essential for quantum technologies. It is fabricated in a hybrid superconducting circuit, featuring an Indium Arsenide (InAs) nanowire doped with unpaired spin surface states and superconducting aluminum leads. This work indicates that the ferromagnetic polarization of these spin states converts into a persistent phase polarization along the nanowire, leading to an anomalous Josephson effect. By applying an external magnetic field, the phase polarization can be adjusted, enabling the quantum phase battery to charge and discharge. The observed behaviors align with theoretical predictions, highlighting the significant interplay between charge, spin, and superconducting phase in the system.
