Elliptic genus of E-strings [PDF]

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

Compactified webs and domain wall partition functions [PDF]

European Physical Journal C: Particles and Fields, 2017
In this paper we use the topological vertex formalism to calculate a generalization of the “domain wall” partition function of M-strings. This generalization allows calculation of partition function of certain compactified webs using a simple gluing ...

Observation of vortex-string chiral modes in metamaterials [PDF]

Nature Communications
As hypothetical topological defects in the geometry of spacetime, vortex strings could have played many roles in cosmology, and their distinct features can provide observable clues about the early universe’s evolution.

Quantum dynamics of topological strings in a frustrated Ising antiferromagnet

npj Quantum Materials, 2022
We investigate the quantum dynamics of the antiferromagnetic transverse field Ising model on the triangular lattice through large-scale quantum Monte Carlo simulations and stochastic analytic continuation.

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.

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.

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 ...

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
