Atomically-precise Vacancy-assembled Quantum Antidots
Hanyan Fang, Harshitra Mahalingam, Xinzhe Li +16
Patterning antidots ("voids") into well-defined antidot lattices creates an intriguing class of artificial structures for the periodic modulation of 2D electron systems, leading to…
Correlation Length, Universality Classes, and Scaling Laws Associated with Topological Phase Transitions
Wei Chen, Markus Legner, Andreas Rüegg +1
The correlation functions related to topological phase transitions in inversion-symmetric lattice models described by Dirac Hamiltonians are discussed. In one dimension…
Majorana and fractionally charged bound states in 1-D Rashba nanowire under spatially varying Zeeman fields
Xiaoyu Zhu, Wei Chen, R. Shen +1
We study topological phase transitions in one dimensional (1-D) Rashba nanowire under a spatially varying Zeeman field when coupled to an -wave superconductor substrate. We show…
Dissipationless Multiferroic Magnonics
Wei Chen, Manfred Sigrist
We propose that the magnetoelectric effect in multiferroic insulators with coplanar antiferromagnetic spiral order, such as BiFeO, enables electrically controlled dissipation…
