Multi-flavor string-net models
Chien-Hung Lin
We generalize the string-net construction to multiple flavors of strings, each of which is labeled by the elements of an abelian group . The same flavor of strings can branch…
Anyon condensation in the string-net models
Chien-Hung Lin, Fiona J. Burnell
We study condensation of abelian bosons in string-net models, by constructing a family of Hamiltonians that can be tuned through any such transition. We show that these Hamiltonian…
Systematic {\em ab initio} study of the phase diagram of epitaxially strained SrTiO
Chien-Hung Lin, Chih-Meng Huang, G. Y. Guo
We use density-functional theory with the local-density approximation to study the structural and ferroelectric properties of SrTiO under misfit strains. Both the antiferrodist…
Zero bias conductance peak in Majorana wires made of semiconductor-superconductor hybrid structures
Chien-Hung Lin, Jay D. Sau, S. Das Sarma
Motivated by a recent experimental report[1] claiming the likely observation of the Majorana mode in a semiconductor-superconductor hybrid structure[2,3,4,5], we study theoreticall…
Emergence of supersymmetric quantum electrodynamics
Shao-Kai Jian, Chien-Hung Lin, Joseph Maciejko +1
Supersymmetric (SUSY) gauge theories such as the Minimal Supersymmetric Standard Model play a fundamental role in modern particle physics, but have not been verified so far in natu…
Quantum rotor theory of spinor condensates in tight traps
Ryan Barnett, Hoi-Yin Hui, Chien-Hung Lin +2
In this work, we theoretically construct exact mappings of many-particle bosonic systems onto quantum rotor models. In particular, we analyze the rotor representation of spinor Bos…
