-corrected Poisson-Lie T-duality
Falk Hassler, Thomas Rochais
We propose leading order -corrections to the Poisson-Lie T-duality transformation rules of the metric, -field, and dilaton. Based on Double Field Theory, whose corrections t…
Geometric Approach to 3D Interfaces at Strong Coupling
Markus Dierigl, Jonathan J. Heckman, Thomas B. Rochais +1
We study 4D systems in which parameters of the theory have position dependence in one spatial direction. In the limit where these parameters jump, this can lead to 3D interfaces su…
Geometric Unification of Higgs Bundle Vacua
Mirjam Cvetic, Jonathan J. Heckman, Thomas B. Rochais +2
Higgs bundles are a central tool used to study a range of intersecting brane systems in string compactifications. Solutions to the internal gauge theory equations of motion for the…
T-Branes, String Junctions, and 6D SCFTs
Falk Hassler, Jonathan J. Heckman, Thomas B. Rochais +2
Recent work on 6D superconformal field theories (SCFTs) has established an intricate correspondence between certain Higgs branch deformations and nilpotent orbits of flavor symmetr…
Gibbs Phenomenon of Framelet Expansions and Quasi-projection Approximation
Bin Han
The Gibbs phenomenon is widely known for Fourier expansions of periodic functions and refers to the phenomenon that the th Fourier partial sums overshoot a target function at ju…
