An a priori C0-estimate for the Fu-Yau equation on compact almost astheno-Kähler manifolds

open access: yesComplex Manifolds, 2022
We investigate the Fu-Yau equation on compact almost astheno-Kähler manifolds and show an a priori C0-estiamte for a smooth solution of the equation.

Localization and duality for ABJM latitude Wilson loops

open access: yesJournal of High Energy Physics, 2021
We investigate several aspects of BPS latitude Wilson loops in gauge theories in three dimensions with N $$ \mathcal{N} $$ ≥ 4 supersymmetry. We derive a matrix model for the bosonic latitude Wilson loop in ABJM using supersymmetric localization, and ...

Connection between the winding number and the Chern number [PDF]

open access: yesChinese Journal of Physics, 2021
Bulk-edge correspondence is one of the most distinct properties of topological insulators. In particular, the 1D winding number $\n$ has a one-to-one correspondence to the number of edge states in a chain of topological insulators with boundaries. By properly choosing the unit cells, we carry out numerical calculation to show explicitly in the extended

On a k-th Gauduchon almost Hermitian manifold

open access: yesComplex Manifolds, 2022
We characterize the k-th Gauduchon condition and by applying its characterization, we reprove that a compact k-th Gauduchon, semi-Kähler manifold becomes quasi-Kähler, which tells us that in particular, a compact almost pluriclosed, semi-Kähler manifold ...

Searching for a Connection Between Matroid Theory and String Theory [PDF]

open access: yes, 2002
We make a number of observations about matter-ghost string phase, which may eventually lead to a formal connection between matroid theory and string theory.

Estimates for a function on almost Hermitian manifolds

open access: yesComplex Manifolds, 2021
We study some estimates for a real-valued smooth function φ on almost Hermitian manifolds. In the present paper, we show that ∂∂∂̄ φ and ∂̄∂∂̄ φ can be estimated by the gradient of the function φ.

Generalized real-space Chern number formula and entanglement hamiltonian

open access: yesSciPost Physics, 2023
We generalize a real-space Chern number formula for gapped free fermions to higher orders. Using the generalized formula, we prove recent proposals for extracting thermal and electric Hall conductance from the ground state via the entanglement ...

Chern-Simons theory and BCS superconductivity [PDF]

open access: yes, 2001
We study the relationship between the holomorphic unitary connection of Chern-Simons theory with temporal Wilson lines and the Richardson's exact solution of the reduced BCS Hamiltonian.

Chiral And Parity Anomalies At Finite Temperature And Density [PDF]

open access: yes, 1997
Two closely related topological phenomena are studied at finite density and temperature. These are chiral anomaly and Chern-Simons term. By using different methods it is shown that $\mu^2 = m^2$ is the crucial point for Chern-Simons at zero temperature ...

Higher-group symmetries and weak gravity conjecture mixing

open access: yesJournal of High Energy Physics, 2022
In four-dimensional axion electrodynamics, a Chern-Simons coupling of the form θF ^ F leads to a higher-group global symmetry between background gauge fields.
