Mathematical Physics, Quantum Fields and ML

Research

We conduct research at the interface of mathematics and theoretical physics, with a particular emphasis on the mathematical structures that arise in Quantum Field Theory and String Theory.

We also pioneered the introduction of Machine Learning tools in order to study the dynamics and moduli spaces of supersymmetric gauge theories realized in String Theory.

Our research group also works on applied problems that appear in industry, where we use fundamental concepts from geometry, topology and machine learning to solve Optimization and Automation Problems.

RESEARCH HIGHLIGHTS

phase diagrams for supersymmetric gauge theories obtained using ML

We can make use of unsupervised machine learning techniques to construct phase diagrams for 4-dimensional supersymmetric gauge theories related to toric Calabi-Yau 3-folds. These phase diagrams help us to study gauge theory phenomena such as Seiberg duality.

new brane configurations realizing supersymmetric gauge theories

Brane Brick Models are Type IIA brane configurations that encode 2d supersymmetric gauge theories corresponding to toric Calabi-Yau 4-folds. Brane Brick Models can be used to study gauge theory phenomena such as Gadde-Gukov-Putrov triality.

geometric unification of supersymmetric gauge theories across spacetime dimensions

Calabi-Yau mirror symmetry leads to a geometric unification of dualities in different spacetime dimensions. It is a powerful that helped us to discover new gauge theory phenomena in different spacetime dimensions.

exploration of hidden mathematical structures with physical implications

By studying various geometrical quantities for non-compact toric Calabi-Yau n-folds defined as cones over Gorenstein Fano varieties, we were able to conjecture new bounds for the volume of the associated Sasaki-Einstein base manifolds.
