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.

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 ...

Topological string geometry

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.

Magnetic skyrmion braids

Nature Communications, 2021
Skyrmions are topological two-dimensional spin textures that in three-dimensional systems resemble strings or tubes. Here, using transmission electron microscopy Zheng et al observe the braiding of skyrmion strings in FeGe and predict this phenomenon for

Topological strings and Wilson loops

Journal of High Energy Physics, 2022
We propose the refined topological string correspondence to the expectation values of half-BPS Wilson loop operators in 5d N $$ \mathcal{N} $$ = 1 gauge theory partition function on the Omega-deformed background ℝ ϵ 1 , 2 4 $$ {\mathbb{R}}_{\upepsilon_{1,

Topological strings on elliptic fibrations [PDF]

Communications in Number Theory and Physics, 2014
We study topological string theory on elliptically fibered Calabi-Yau threefolds using mirror symmetry. We compute higher genus topological string amplitudes and express these in terms of polynomials of functions constructed from the special geometry of the moduli space. The polynomials are fixed by the holomorphic anomaly equations supplemented by the

Stability of topological solitons, and black string to bubble transition

Journal of High Energy Physics, 2022
We study the existence of smooth topological solitons and black strings as locally-stable saddles of the Euclidean gravitational action of five dimensional Einstein-Maxwell theory.

Elliptic genus of E-strings

Journal of High Energy Physics, 2017
We study a family of 2d N = 0 , 4 $$ \mathcal{N}=\left(0,\ 4\right) $$ gauge theories which describes at low energy the dynamics of E-strings, the M2-branes suspended between a pair of M5 and M9 branes. The gauge theory is engineered using a duality with
