June 21, 2018 - Moving into the new lab
![]() | Moving equipment into the new lab in the renovated Swain Hall. Looks like most of the utilities are ready - unlike our temporary relocation to MESH Hall. |

![]() | Two rotating anode x-ray generators are loaded onto a flat bed trailer for the move back to Swain Lab. Fortunately the rain predicted for the day held off until the move was complete. |
![]() | After 2 years in temporary lab space at the Multidisciplinary Engineering and Science Hall the lab is getting prepared to move back to newly renovated laboratory space in Swain Hall. |
![]() | "Maxon and roton measurements in nanoconfined 4He" by Matt Bryan and Paul Sokol has appeared on-line in Physical Review B |
![]() | A manuscript describing the filling dependence of the maxon and roton in 4He has been posted on arXiv. Previous studies have suggested that the confined liquid behaves as a bulk liquid at negative pressures and that the maxon provided a direct measure of the pressure. This study shows that the maxon and roton imply different densities of the confined liquid and that it cannot be treated simply as a bulk liquid at negative pressures. |
![]() | Adrian Del Maestro (University of Vermont) and Paul Sokol receive funding from the Condensed Matter Physics and the Condensed Matter and Matterials Theory programs in the Division of Materials Research at NSF for a joint experimental and theoretical effort to study the Luttinger Liquid behavior of 4He confined in 1 dimensional channels. |
![]() | "The Momentum Distribution of Liquid 4He" appears in the Journal of Low Temperature Physics. This joint experimental and theoretical study observes excellent agreement between experimental measurements of the momentum distribution and Quantum Mante Carlo of the momentum distribution and final state effects as a function of temperature. |
![]() | "Bulklike excitations in nanoconfined helium" appears in Physical Review B. This study shows that the roton lifetime in confinement is identical in the bulk indicating rotons scatter elastically at the pore walls. |
