Phase-preserving linear amplifiers not simulable by the parametric amplifier
A. Chia, M. Hajdusek, R. Nair +3
It is commonly accepted that a parametric amplifier can simulate a phase-preserving linear amplifier regardless of how the latter is realized [Caves et al., Phys. Rev. A 86, 063802…

Majorana Quasi-Particles Protected by Angular Momentum Conservation
F. Iemini, L. Mazza, L. Fallani +3
We show how angular momentum conservation can stabilise a symmetry-protected quasi-topological phase of matter supporting Majorana quasi-particles as edge modes in one-dimensional…
