Topological and unconventional states of matter [PDF]

open access: yes, 2019
Topology is the study of geometrical objects which are equivalent under continuous deformations. The concept of topology can be relevant to the physics of condensed matter systems.

Fermion condensation and gapped domain walls in topological orders

open access: yesJournal of High Energy Physics, 2017
We study fermion condensation in bosonic topological orders in two spatial dimensions. Fermion condensation may be realized as gapped domain walls between bosonic and fermionic topological orders, which may be thought of as real-space phase transitions ...

Fusion rules and shrinking rules of topological orders in five dimensions

open access: yesJournal of High Energy Physics, 2023
As a series of work about 5D (spacetime) topological orders, here we employ the path-integral formalism of 5D topological quantum field theory (TQFT) established in Zhang and Ye, JHEP 04 (2022) 138 to explore non-Abelian fusion rules, hierarchical ...

Anyonic exclusions statistics on surfaces with gapped boundaries

open access: yesJournal of High Energy Physics, 2019
An anyonic exclusion statistics, which generalizes the Bose-Einstein and Fermi-Dirac statistics of bosons and fermions, was proposed by Haldane [1].

Vacancy-induced bound states in topological insulators [PDF]

open access: yes, 2011
We present an exact solution of a modified Dirac equation for topological insulator in the presence of a hole or vacancy to demonstrate that vacancies can induce bound states in the band gap of topological insulators.

Spin pumping in ferromagnet-topological insulator-ferromagnetheterostructures [PDF]

open access: yes, 2015
Topological insulators (TIs) are enticing prospects for the future of spintronics due to their large spin-orbit coupling and dissipationless, counter-propagating conduction channels in the surface state.

Bandgap-assisted quantum control of topological edge states in a cavity

open access: yesPhysical Review Research, 2020
Quantum matter with exotic topological order has potential applications in quantum computation. However, in present experiments, the manipulations on topological states are still challenging.

Nontrivial topological states on a Möbius band [PDF]

open access: yes, 2014
In the field of topological insulators, the topological properties of quantum states in samples with simple geometries, such as a cylinder or a ribbon, have been classified and understood during the past decade.

New states of matter suggested by new topological structures [PDF]

open access: yesInternational Journal of General Systems, 2013
We extend the well-known Borromean and Brunnian rings to new higher order versions. Then we suggest an extension of the connection between Efimov states in cold gases and Borromean and Brunnian rings to these new higher order links. This gives rise to a whole new hierarchy of possible states with Efimov states at the bottom.

Topological orders, braiding statistics, and mixture of two types of twisted BF theories in five dimensions

open access: yesJournal of High Energy Physics, 2022
Topological orders are a prominent paradigm for describing quantum many-body systems without symmetry-breaking orders. We present a topological quantum field theoretical (TQFT) study on topological orders in five-dimensional spacetime (5D) in which ...
