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…
Continuous transition between Ising magnetic order and a chiral spin liquid
G. Shankar, Chien-Hung Lin, Joseph Maciejko
The competition between fractionalized spin-liquid states and magnetically ordered phases is an important paradigm in frustrated magnetism. Spin-orbit coupled Mott insulators with…
Generalized string-net models: A thorough exposition
Chien-Hung Lin, Michael Levin, Fiona J. Burnell
We describe how to construct generalized string-net models, a class of exactly solvable lattice models that realize a large family of 2D topologically ordered phases of matter. The…
Transition between algebraic and quantum spin liquids at large
Rufus Boyack, Chien-Hung Lin, Nikolai Zerf +2
We present a field theory description of a quantum phase transition in two spatial dimensions between a algebraic spin liquid with flavors of gapless two-component Dirac…
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…
Interacting fermionic symmetry-protected topological phases in two dimensions
Chenjie Wang, Chien-Hung Lin, Zheng-Cheng Gu
We classify and construct models for two-dimensional (2D) interacting fermionic symmetry-protected topological (FSPT) phases with general finite Abelian unitary symmetry . To…
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…
Superconducting quantum criticality of topological surface states at three loops
Nikolai Zerf, Chien-Hung Lin, Joseph Maciejko
The semimetal-superconductor quantum phase transition on the two-dimensional (2D) surface of a 3D topological insulator is conjectured to exhibit an emergent supers…
Bulk-boundary correspondence for three-dimensional symmetry-protected topological phases
Chenjie Wang, Chien-Hung Lin, Michael Levin
We derive a bulk-boundary correspondence for three-dimensional (3D) symmetry-protected topological (SPT) phases with unitary symmetries. The correspondence consists of three equati…
Loop braiding statistics in exactly soluble 3D lattice models
Chien-Hung Lin, Michael Levin
We construct two exactly soluble lattice spin models that demonstrate the importance of three-loop braiding statistics for the classification of 3D gapped quantum phases. The two m…
Generalizations and limitations of string-net models
Chien-Hung Lin, Michael Levin
We ask which topological phases can and cannot be realized by exactly soluble string-net models. We answer this question for the simplest class of topological phases, namely those…
Quantum Dynamics of Disordered Bosons in an Optical Lattice
Chien-Hung Lin, Rajdeep Sensarma, K. Sengupta +1
We study the equilibrium and non-equilibrium properties of strongly interacting bosons on a lattice in presence of a random bounded disorder potential. Using a Gutzwiller projected…
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…
Low-density molecular gas of tightly-bound Rashba-Dresselhaus fermions
So Takei, Chien-Hung Lin, Brandon M. Anderson +1
We study interacting Rashba-Dresselhaus fermions in two spatial dimensions. First, we present a new exact solution to the two-particle pairing problem of spin-orbit-coupled fermion…
Majorana resonances and how to avoid them in periodic topological superconductor-nanowire structures
Jay D. Sau, Chien Hung Lin, Hoi-Yin Hui +1
Semiconducting nanowires in proximity to superconductors are promising experimental systems for Majorana fermions which may ultimately be used as building blocks for topological qu…
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…
Interaction induced ferro-electricity in the rotational states of polar molecules
Chien-Hung Lin, Yi-Ting Hsu, Hao Li +1
We show that a ferro-electric quantum phase transition can be driven by the dipolar interaction of polar molecules in the presence a micro-wave field. The obtained ferro-electricit…
Nanomechanical-resonator-assisted induced transparency in a Cooper-pair-box system
Xiao-Zhong Yuan, Hsi-Sheng Goan, Chien-Hung Lin +2
We propose a scheme to demonstrate the electromagnetically induced transparency (EIT) in a system of a superconducting Cooper-pair box coupled to a nanomechanical resonator. In thi…
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…
