Calculation of the exchange integrals in solid3He
Calculations are performed for two-, three-, and four-particle exchange in the quantum crystal of bcc solid3He. The quasiclassical approximation is used to find the tunneling path in the space of all atomic coord...

Vortex arrays of coexisting singly and doubly quantized vortex lines in3He-A
In superfluid3He-A singly and doubly quantized vortex lines can coexist in a rotating container. We measure with NMR techniques the radial distribution of the two vortex types in an array of vortex lines. The rad...
