Revisiting the Poor Man's Majoranas: The Spin-Exchange Induced Spillover Effect
J. E. Sanches, T. M. Sobreira, L. S. Ricco +2
We give a review on Poor Man's Majorana (PMM) modes, which are theoretically established in the minimal Kitaev chain implementation consisting of two grounded, spinless quantum dot…

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…

Unveiling the interdisciplinary character of negative pressure
Francisco F. Barbosa, Lucas Squillante, Luciano Ricco +3
We explore the concept of negative pressure and its relevance in a variety of physical contexts: the expansion of the universe, mixture theory, cavitation, and the capillary effect…
