Entanglement Spectrum in Superfluid Phases of 3He
The entanglement spectrum of superfluid phases of 3He, the 3D B-phase and the planar phase in two dimensions, has been analyzed. The wavefunctions of the low-lying eigenstates, including Majorana zero modes, as well as the corresponding part of the spectrum of the entanglement Hamiltonian, have been found explicitly.
