Summary
In high magnetic fields, the superfluid transition of Helium-3 in aerogel splits into two distinct transitions. A new superfluid phase, the beta phase, is observed between these transitions, consistent with theoretical predictions.
Area of Science:
- Low-temperature physics
- Condensed matter physics
- Superfluidity
Background:
- Superfluid transition of Helium-3 in nematic aerogel typically occurs into the polar phase in low magnetic fields.
- Understanding phase transitions in confined quantum fluids is crucial.
Purpose of the Study:
- Investigate the superfluid transition of Helium-3 in nematic aerogel under high magnetic fields.
- Characterize the newly predicted superfluid beta phase.
Main Methods:
- Utilized a vibrating aerogel resonator to precisely measure transition temperatures.
- Observed the splitting of the superfluid transition in response to varying magnetic fields.
Main Results:
- The superfluid transition splits into two discrete transitions at different temperatures in high magnetic fields.
- Identified a new superfluid phase, the beta phase, existing between these two transitions.
- Measured the temperature range of the beta phase as a function of magnetic field.
Conclusions:
- Experimental results align well with theoretical expectations for the superfluid beta phase.
- High magnetic fields induce a novel phase in superfluid Helium-3 confined within aerogel.

44.8K
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

46.7K
Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, and solubilities (miscibilities) of substances. Molar mass, molecular shape, and polarity affect the strength of different intermolecular forces, which influence the magnitude of physical properties across a family of molecules.
Temporary attractive forces like dispersion are present in all molecules, whether they are polar or nonpolar. They...

The phase of a given substance depends on the pressure and temperature. Thus, plots of pressure versus temperature showing the phase in each region provide considerable insights into the thermal properties of substances. Such plots are known as phase diagrams. For instance, in the phase diagram for water (Figure 1), the solid curve boundaries between the phases indicate phase transitions (i.e., temperatures and pressures at which the phases coexist).

19.6K
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they were assumed to be nonreactive since they have filled valence shells. In 1962, Dr. Neil Bartlett at the University of British Columbia proved this assumption to be false.

1.4K
The internal energy of a substance—the total kinetic energy of all its molecules and the potential energy of their associated forces—depends on the strength of the intermolecular forces in the condensed phases and the pressure exerted on the substance. The internal energy of a substance is the highest in the gaseous state, the lowest in the solid state, and intermediate in the liquid state. Phase transitions are caused by changes in physical conditions, such as temperature and...

18.3K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...
