Towards the manipulation of topological states of matter: A perspective from electron transport [PDF]

open access: yesScience Bulletin, 2018
The introduction of topological invariants, ranging from insulators to metals, has provided new insights into the traditional classification of electronic states in condensed matter physics. A sudden change in the topological invariant at the boundary of

Geometric Test for Topological States of Matter [PDF]

open access: yesPhysical Review Letters, 2022
We generalize the flux insertion argument due to Laughlin, Niu-Thouless-Tao-Wu, and Avron-Seiler-Zograf to the case of fractional quantum Hall states on a higher-genus surface. We propose this setting as a test to characterise the robustness, or topologicity, of the quantum state of matter and apply our test to the Laughlin states. Laughlin states form

Exploring nonlinear topological states of matter with exciton-polaritons: Edge solitons in kagome lattice. [PDF]

open access: yesSci Rep, 2017
AbstractMatter in nontrivial topological phase possesses unique properties, such as support of unidirectional edge modes on its interface. It is the existence of such modes which is responsible for the wonderful properties of a topological insulator – material which is insulating in the bulk but conducting on its surface, along with many of its ...

Gravitational response of topological quantum states of matter

open access: yesPhysical Review B, 2023
Identifying novel topological properties of topological quantum states of matter, such as exemplified by the quantized Hall conductance, is a valuable step towards realizing materials with attractive topological attributes that guarantee their imperviousness to realistic imperfections, disorder and environmental disturbances.

Skeleton of matrix-product-state-solvable models connecting topological phases of matter [PDF]

open access: yesPhysical Review Research, 2021
Models whose ground states can be written as an exact matrix product state (MPS) provide valuable insights into phases of matter. While MPS-solvable models are typically studied as isolated points in a phase diagram, they can belong to a connected network of MPS-solvable models, which we call the MPS skeleton.

Topological states of condensed matter

open access: yesNature Materials, 2017
Topological states of quantum matter have been investigated intensively in recent years in materials science and condensed matter physics. The field developed explosively largely because of the precise theoretical predictions, well-controlled materials processing, and novel characterization techniques.

Bell’s inequality and entanglement in qubits

open access: yesJournal of High Energy Physics, 2017
We propose an alternative evaluation of quantum entanglement by measuring the maximum violation of the Bell’s inequality without information of the reduced density matrix of a system. This proposal is demonstrated by bridging the maximum violation of the

Crystallographic interacting topological phases and equivariant cohomology: to assume or not to assume

open access: yesJournal of High Energy Physics, 2021
For symmorphic crystalline interacting gapped systems we derive a classification under adiabatic evolution. This classification is complete for non-degenerate ground states.

Choreographed entanglement dances: Topological states of quantum matter [PDF]

open access: yesScience, 2019
A topological paradigm shift The discovery of topological phases of matter forced condensed matter physicists to question and reexamine some of the basic notions of their discipline. Wen reviews the progress of the field that took a sharp turn from Landau's broken symmetry paradigm to arrive at the modern notions of topological order and ...
