Crosscap resurgence and Riemann--Hilbert problems for orientifolded conifolds
Wu-yen Chuang, Yi-Jing Tseng
We study the crosscap contribution to the large- SO/Sp free energy of the orientifolded conifold by comparing its formal expansion with Faddeev's quantum dilogarithm. This deter…
Nonperturbative refined topological string
Wu-Yen Chuang
A formula for the full nonperturbative topological string free energy was recently proposed by Hattab and Palti \cite{HP24a}. In this work, we extend their result to the refined to…
Twisted spectral correspondence and torus knots
Wu-yen Chuang, Duiliu-Emanuel Diaconescu, Ron Donagi +2
Cohomological invariants of twisted wild character varieties as constructed by Boalch and Yamakawa are derived from enumerative Calabi-Yau geometry and refined Chern-Simons invaria…
On Some Computations of Higher Rank Refined Donaldson-Thomas Invariants
Wu-yen Chuang, Chien-Hsun Wang
We present some computations of higher rank refined Donaldson-Thomas invariants on local curve geometries, corresponding to local D6-D2-D0 or D4-D2-D0 configurations. A refined wal…
Parabolic refined invariants and Macdonald polynomials
Wu-yen Chuang, Duiliu-Emanuel Diaconescu, Ron Donagi +1
A string theoretic derivation is given for the conjecture of Hausel, Letellier, and Rodriguez-Villegas on the cohomology of character varieties with marked points. Their formula is…
Geometric engineering of (framed) BPS states
Wu-yen Chuang, Duiliu-Emanuel Diaconescu, Jan Manschot +2
BPS quivers for N=2 SU(N) gauge theories are derived via geometric engineering from derived categories of toric Calabi-Yau threefolds. While the outcome is in agreement of previous…
BPS states and the P=W conjecture
W. -Y. Chuang, D. -E. Diaconescu, G. Pan
A string theoretic framework is presented for the work of Hausel and Rodriguez-Vilegas as well as de Cataldo, Hausel and Migliorini on the cohomology of character varieties. The ce…
D-branes, surface operators, and ADHM quiver representations
U. Bruzzo, W. -y. Chuang, D. -E. Diaconescu +3
A supersymmetric quantum mechanical model is constructed for BPS states bound to surface operators in five dimensional SU(r) gauge theories using D-brane engineering. This model re…
Dynamical Instability of Holographic QCD at Finite Density
Wu-yen Chuang, Shou-Huang Dai, Shoichi Kawamoto +2
In this paper we study the dynamical instability of Sakai-Sugimoto's holographic QCD model at finite baryon density. In this model, the baryon density, represented by the smeared i…
BPS State Counting in Local Obstructed Curves from Quiver Theory and Seiberg Duality
Wu-yen Chuang, Guang Pan
In this paper we study the BPS state counting in the geometry of local obstructed curve with normal bundle O+O(-2). We find that the BPS states have a framed quiver description. Us…
Wall Crossing of BPS States on the Conifold from Seiberg Duality and Pyramid Partitions
Wu-yen Chuang, Daniel L. Jafferis
In this paper we study the relation between pyramid partitions with a general empty room configuration (ERC) and the BPS states of D-branes on the resolved conifold. We find that t…
Flux-induced isometry gauging in heterotic strings
Wu-yen Chuang, Peng Gao
We study the effect of flux-induced isometry gauging of the scalar manifold in N=2 heterotic string compactification with gauge fluxes. We show that a vanishing theorem by Witten p…
Topological twisted sigma model with H-flux revisited
Wu-yen Chuang
In this paper we revisit the topological twisted sigma model with H-flux. We explicitly expand and then twist the worldsheet Lagrangian for bi-Hermitian geometry. we show that the…
Complex/Symplectic Mirrors
Wu-yen Chuang, Shamit Kachru, Alessandro Tomasiello
We construct a class of symplectic non--Kaehler and complex non--Kaehler string theory vacua, extending and providing evidence for an earlier suggestion by Polchinski and Strominge…
A Note on Mirror Symmetry for Manifolds with Spin(7) Holonomy
Wu-yen Chuang
Starting from the superconformal algebras associated with manifolds, I extend the algebra to the manifolds with spin(7) holonomy. I show how the mirror symmetry in manifolds…
