Precise estimation of the coupling strength between two nanomechanical modes from four Ramsey fringes
arXiv:2601.13415v1 Announce Type: new Abstract: We experimentally determine the coupling strength between two strongly coupled nanomechanical modes using a Ramsey-inspired technique optimized for signals as short as four fringes. The method is applied to precisely probe the change of the coupling rate induced by a modi...

Confined non-Hermitian skin effect in a semi-infinite Fock-state lattice
arXiv:2601.13540v1 Announce Type: new Abstract: In this paper, we investigate the non-Hermitian skin effect in a semi-infinite Fock-state lattice, where the inherent coupling scales as \sqrt{n}. By analytically solving a non-uniform, non-reciprocal SSH model, we demonstrate that the intrinsic inhomogeneous coupling, in...
