Webminimizes the energy is then used as an approximation for the true ground-state. How good this approximation is depends, of course, on how skilled we are in making a judicious choice for the form of the trial wavefunctions.

WebRecently it was shown that anyons on the two-sphere naturally arise from a system of molecular impurities exchanging angular momentum with a many-particle bath (Phys. Rev. Lett. 126, 015301 (2024)). Here we further advance this approach and rigorously demonstrate that in the experimentally realized regime the lowest spectrum of two linear … WebAbstract: In the absence of frustration, interacting bosons in the ground state exist either in the superfluid or insulating phases. Superfluidity corresponds to frictionless flow of the matter field, and in optical conductivity is revealed through a distinct $\delta$-functional peak at zero frequency with the amplitude known as the Drude weight. Superfluid helium-4 is the superfluid form of helium-4, an isotope of the element helium. A superfluid is a state of matter in which matter behaves like a fluid with zero viscosity. The substance, which looks like a normal liquid, flows without friction past any surface, which allows it to continue to circulate over … See more Known as a major facet in the study of quantum hydrodynamics and macroscopic quantum phenomena, the superfluidity effect was discovered by Pyotr Kapitsa and John F. Allen, and Don Misener in 1937. It has since been … See more Recently in the field of chemistry, superfluid helium-4 has been successfully used in spectroscopic techniques as a quantum solvent. Referred to as superfluid helium droplet spectroscopy (SHeDS), it is of great interest in studies of gas molecules, as a … See more Landau two-fluid approach L. D.
