Quantum geometry of refined topological strings
A bstractWe consider branes in refined topological strings. We argue that their wavefunctions satisfy a Schrödinger equation depending on multiple times and prove this in the case where theExpand

Dimers and orientifolds
We introduce new techniques based on brane tilings to investigate D3-branes probing orientifolds of toric Calabi-Yau singularities. With these new tools, one can write down many orientifold modelsExpand

Gaugino Condensates and D-terms from D7-branes
We investigate, at the microscopic level, the compatibility between D-term potentials from world-volume fluxes on D7-branes and non-perturbative superpotentials arising from gaugino condensation on aExpand

UvA-DARE ( Digital Academic Repository ) Quantum Geometry of Refined Topological Strings
We consider branes in refined topological strings. We argue that their wavefunctions satisfy a Schrödinger equation depending on multiple times and prove this in the case where the topological stringExpand

Extended Holomorphic Anomaly in Gauge Theory
The partition function of an $${\mathcal {N}=2}$$ gauge theory in the Ω-background satisfies, for generic value of the parameter $${\beta=-{\epsilon_1}/{\epsilon_2}}$$ , the, in general extended, butExpand

Real mirror symmetry for one-parameter hypersurfaces
We study open string mirror symmetry for one-parameter Calabi-Yau hyper- surfaces in weighted projective space. We identify mirror pairs of D-brane configurations, derive the correspondingExpand

Shift versus Extension in Refined Partition Functions
We have recently shown that the global behavior of the partition function of N=2 gauge theory in the general Omega-background is captured by special geometry in the guise of the (extended)Expand

The Real Topological Vertex at Work
We develop the real vertex formalism for the computation of the topological string partition function with D-branes and O-planes at the fixed point locus of an anti-holomorphic involution actingExpand

Gauge theory analog of some stringy D-instantons
We argue that one can see a specific class of 'stringy' D-instantons in the underlying 4D gauge theory as the UV completion of an ordinary gauge instanton of a completely broken gauge groupExpand

Machine learning of Calabi-Yau volumes
We employ machine learning techniques to investigate the volume minimum of Sasaki-Einstein base manifolds of noncompact toric Calabi-Yau three-folds. We find that the minimum volume can be approximExpand
