Planar and Nematic Aerogels: DLCA and Superfluid 3He
M. D. Nguyen, J. S. Simon, J. W. Scott +3
We perform cluster aggregation simulations to model the structure of anisotropic aerogel. By biasing the diffusion process, we are able to obtain two distinct types of globally ani…
Electron-beam Floating-zone Refined UCoGe
K. E. Avers, M. D. Nguyen, J. W. Scott +6
The interplay between unconventional superconductivity and quantum critical ferromagnetism in the U-Ge compounds represents an open problem in strongly correlated electron systems.…
Electric field tunable unconventional superconductivity in alternating twist magic-angle trilayer graphene
Zeyu Hao, A. M. Zimmerman, Patrick Ledwith +6
We construct a van der Waals heterostructure consisting of three graphene layers stacked with alternating twisting angles . At the average twist angle , a…
The Effect of Magnetic Impurities on Superfluid He in Aerogel
A. M. Zimmerman, M. D. Nguyen, J. W. Scott +1
The critical field for superfluid He in axially compressed, anisotropic silica aerogel is shown to be the result of an anisotropic distribution of magnetic impurities affecting…
Corrections to the Higgs Mode Masses in Superfluid 3He
M. D. Nguyen, A. M. Zimmerman, W. P. Halperin
Superfluid 3He has a rich spectrum of collective modes with both massive and massless excitations. The masses of these modes can be precisely measured using acoustic spectroscopy a…
Orbital-Flop Transition of Angular Momentum in a Topological Superfluid
A. M. Zimmerman, J. I. A. Li, M. D. Nguyen +1
The direction of the orbital angular momentum of the -phase of superfluid He can be controlled by engineering the anisotropy of the silica aerogel framework within which it…
NMR Frequency Shifts and Phase Identification in Superfluid He
A. M. Zimmerman, M. D. Nguyen, W. P. Halperin
The pressure dependence of the order parameter in superfluid He is amazingly simple. In the Ginzburg-Landau regime, i.e. close to , the square of the order parameter can b…
Anisotropic phases of superfluid 3He in compressed aerogel
J. I. A. Li, A. M. Zimmerman, J. Pollanen +2
It has been shown that the relative stabilities of various superfluid states of 3He can be influenced by anisotropy in a silica aerogel framework. We prepared a suite of aerogel sa…
Stability of superfluid 3He-B in compressed aerogel
J. I. A. Li, A. M. Zimmerman, J. Pollanen +3
In recent work it was shown that new anisotropic p-wave states of superfluid 3He can be stabilized within high porosity silica aerogel under uniform positive strain [1]. In contras…
The Superfluid Glass Phase of 3He-A
J. I. A. Li, J. Pollanen, A. M. Zimmerman +3
It is established theoretically that an ordered state with continuous symmetry is inherently unstable to arbitrarily small amounts of disorder [1, 2]. This principle is of central…
Orientation of the Angular Momentum in Superfluid 3He-A in a Stretched Aerogel
J. I. A. Li, A. M. Zimmerman, J. Pollanen +3
Superfluid 3He-A in a fully characterized stretched aerogel, used in previous work [1], has been studied for parallel and perpendicular orientations of the magnetic field relative…
