From classical to quantum regime of topological surface states via defect engineering
SciPost Physics Lecture Notes, 2022 Since the notion of topological insulator (TI) was envisioned in late 2000s, topology has become a new paradigm in condensed matter physics. Realization of topology as a generic property of materials has led to numerous predictions of topological ...

Topological defects of N\'eel order and Kondo singlet formation for Kondo-Heisenberg model on a honeycomb lattice [PDF]
, 2013 Heavy fermion systems represent a prototypical setting to study magnetic quantum phase transitions. A particular focus has been on the physics of Kondo destruction, which captures quantum criticality beyond the Landau framework of order-parameter ...

Stability of topological wall defects on spheres with n-atic order
Physical Review Research, 2020 Topological point defects on orientationally ordered spheres and on deformable fluid vesicles have been investigated, partly motivated by their potential applications in creating superatoms with directional bonds through functionalization of the “bald ...

Topological phenomena at topological defects
, 2022 There are two prominent applications of the mathematical concept of topology to the physics of materials: band topology, which classifies different topological insulators and semimetals, and topological defects that represent immutable deviations of a solid lattice from its ideal crystalline form.

Dynamics of topological defects in a spiral: a scenario for the spin-glass phase of cuprates [PDF]
, 2004 We propose that the dissipative dynamics of topological defects in a spiral state is responsible for the transport properties in the spin-glass phase of cuprates.

Extended topological group structure due to average reflection symmetry
New Journal of Physics, 2015 We extend the single-particle topological classification of insulators and superconductors to include systems in which disorder preserves average reflection symmetry.

Entanglement entropy in integrable field theories with line defects. Part I. Topological defect
Journal of High Energy Physics, 2017 In this paper and a companion one [1], we study the effect of integrable line defects on entanglement entropy in massive integrable field theories in 1+1 dimensions. The current paper focuses on topological defects that are purely transmissive. Using the

Defects in the 3-dimensional toric code model form a braided fusion 2-category
Journal of High Energy Physics, 2020 It was well known that there are e-particles and m-strings in the 3-dimensional (spatial dimension) toric code model, which realizes the 3-dimensional ℤ2 topological order.

Physical Review Research, 2020 Semimetals exhibiting nodal lines or nodal surfaces represent a novel class of topological states of matter. While conventional Weyl semimetals exhibit momentum-space Dirac monopoles, these more exotic semimetals can feature unusual topological defects ...

Resonant Production of Topological Defects [PDF]
Physical Review Letters, 2000 We describe a novel phenomenon in which vortices are produced due to resonant oscillations of a scalar field which is driven by a periodically varying temperature T, with T remaining much below the critical temperature $T_c$. Also, in a rapid heating of a localized region to a temperature {\it below} $T_c$, far separated vortex and antivortex can form.
