Orbifold string topology [PDF]
Geometry & Topology, 2008 In this paper we study the string topology ( la Chas-Sullivan) of an orbifold. We define the string homology ring product at the level of the free loop space of the classifying space of an orbifold. We study its properties (introducing an operad to do so) and do some explicit calculations.

String Phase in an Artificial Spin Ice
Nature Communications, 2021 Strings of local excitations are interesting features of a strongly correlated topological quantum matter. Here, the authors show that Boltzmann-distributed strings of local excitations also describe the topological physics of the Santa Fe geometry of ...

Topology in thermodynamics of regular black strings with Kaluza–Klein reduction
European Physical Journal C: Particles and Fields, 2023 We study the topological defects in the thermodynamics of regular black strings (from a four-dimensional perspective) that is symmetric under the double Wick rotation and constructed in the high-dimensional spacetime with an extra dimension compactified ...

Codimension-2 defects and higher symmetries in (3+1)D topological phases
SciPost Physics, 2023 (3+1)D topological phases of matter can host a broad class of non-trivial topological defects of codimension-1, 2, and 3, of which the well-known point charges and flux loops are special cases.

Realization of non-Hermitian Hopf bundle matter
Communications Physics, 2023 Non-trivial linking invariant encodes robust information of topological matter. It has been recently shown that the linking and winding of complex eigenenergy strings can classify one-dimensional non-Hermitian topological matter.

String operators for Cheshire strings in topological phases [PDF]
Physical review B, 2023 Elementary point charge excitations in 3+1D topological phases can condense along a line and form a descendant excitation called the Cheshire string. Unlike the elementary flux loop excitations in the system, Cheshire strings do not have to appear as the

Composite topological solitons consisting of domain walls, strings, and monopoles in O(N) models [PDF]
Journal of High Energy Physics, 2023 We study various composites of global solitons consisting of domain walls, strings, and monopoles in linear O(N) models with N = 2 and 3. Spontaneous symmetry breaking (SSB) of the O(N) symmetry down to O(N – 1) results in the vacuum manifold SN−1 ...

Nuclear Physics B, 2020 Perturbative string amplitudes are correctly derived from the string geometry theory, which is one of the candidates of a non-perturbative formulation of string theory. In order to derive non-perturbative effects rather easily, we formulate topological string geometry theory.

Hypermultiplets and topological strings [PDF]
Journal of High Energy Physics, 2006 The c-map relates classical hypermultiplet moduli spaces in compactifications of type II strings on a Calabi-Yau threefold to vector multiplet moduli spaces via a further compactification on a circle. We give an off-shell description of the c-map in N=2 superspace.
