We experimentally observe the decay dynamics of deterministically created isolated monopoles in spin-1 Bose-Einstein condensates. As the condensate undergoes a change between magnetic phases, the isolated monopole gradually evolves into a spin configuration hosting a Dirac monopole in its synthetic magnetic field. We characterize in detail the Dirac monopole by measuring the particle densities of the spin states projected along different quantization axes. Importantly, we observe the spontaneous emergence of nodal lines in the condensate density that accompany the Dirac monopole. We also demonstrate that the monopole decay accelerates in weaker magnetic field gradients.

Geometry of Degeneracy in Potential and Density Space Penz, Markus; van Leeuwen, Robert (Verein zur Forderung des Open Access Publizierens in den Quantenwissenschaften, 2023)In a previous work [J. Chem. Phys. 155, 244111 (2021)], we found counterexamples to the fundamental Hohenberg-Kohn theorem from density-functional theory in finite-lattice systems represented by graphs. Here, we demonstrate ...

Thermodynamics of a Phase-Driven Proximity Josephson Junction Vischi, Francesco; Carrega, Matteo; Braggio, Alessandro; Virtanen, Pauli; Giazotto, Francesco (MDPI, 2019)We study the thermodynamic properties of a superconductor/normal metal/superconductor Josephson junction in the short limit. Owing to the proximity effect, such a junction constitutes a thermodynamic system where phase ...
