Spin-Exchange Induced Spillover on Poor Man's Majoranas in Minimal Kitaev Chains
J. E. Sanches, L. T. Lustosa, L. S. Ricco +5
The "Poor Man's Majoranas" (PMMs) [Phys. Rev. B 86, 134528 (2012)] devoid of topological protection can "spill over" from one edge into another of the minimal Kitaev chain when per…

Higgs-like stiffness and fractons on the verge of phase transitions
Lucas Squillante, Antonio C. Seridonio, Roberto E. Lagos-Monaco +1
In condensed matter Physics, massive longitudinal Higgs modes emerge from fluctuations of the order parameter. A few years ago, the Higgs mode was \emph{caught} experimentally in t…
