Tying Quantum Knots
David S. Hall, Michael W. Ray, Konstantin Tiurev +3
Knots are familiar entities that appear at a captivating nexus of art, technology, mathematics, and science. As topologically stable objects within field theories, they have been s…
Observation of Dirac Monopoles in a Synthetic Magnetic Field
M. W. Ray, E. Ruokokoski, S. Kandel +2
Magnetic monopoles --- particles that behave as isolated north or south magnetic poles --- have been the subject of speculation since the first detailed observations of magnetism s…
Dynamics of Few Co-rotating Vortices in Bose-Einstein Condensates
R. Navarro, R. Carretero-Gonzalez, P. J. Torres +5
We study the dynamics of small vortex clusters with few (2--4) co-rotating vortices in Bose-Einstein condensates by means of experiments, numerical computations, and theoretical an…
Mass flow through solid 4He induced by the fountain effect
M. W. Ray, R. B. Hallock
Using an apparatus that allows superfluid liquid 4He to be in contact with hcp solid \4he at pressures greater than the bulk melting pressure of the solid, we have performed experi…
Mass flux and solid growth in solid 4He: 60 mK - 700 mK
M. W. Ray, R. B. Hallock
We use the thermo-mechanical effect to create a chemical potential difference between two liquid reservoirs connected to each other through Vycor rods in series with solid hcp 4He…
Observation of thermo-mechanical equilibration in the presence of a solid 4He conduit
M. W. Ray, R. B. Hallock
We observe a thermo-mechanical effect when a chemical potential difference is created by a temperature difference imposed between two liquid reservoirs connected to each other thro…
