The superfluidity of interfaces in solid helium-4 (4He) quantum crystals is investigated. Researchers found that these interfaces can become insulating through a quantum phase transition, with implications for understanding nonclassical inertia.

Area of Science:

  • Quantum Crystal Physics
  • Condensed Matter Physics
  • Low-Temperature Physics

Background:

  • The nonclassical moment of inertia observed in solid helium-4 (4He) suggests exotic quantum phenomena.
  • A proposed explanation involves the superfluidity of interfaces between microcrystallites.

Purpose of the Study:

  • To investigate the possibility of superfluidity at the interfaces of solid 4He.
  • To model the behavior of these interfaces using a simple quantum crystal model.

Main Methods:

  • Utilized a checkerboard lattice model for a quantum crystal.
  • Analyzed the conditions under which interface superfluidity can occur.
  • Investigated the quantum phase transition from a superfluid interface to an insulating state.

Main Results:

  • Demonstrated that interface superfluidity can exist across a broad parameter range in the checkerboard model.
  • Showed that strong interparticle interactions drive a quantum phase transition, leading to an insulating interface.
  • Identified the universality class of the transition in 3D (U(1)) and the role of fractional charges in 2D roughening.

Conclusions:

  • Interface superfluidity is a viable mechanism for the nonclassical moment of inertia in solid 4He.
  • The transition to an insulating interface is a key feature, with distinct behaviors in 2D and 3D.
  • Fractionally charged topological excitations play a crucial role in the 2D interface roughening phenomenon.
