The use of experimental data to constrain the values of the Wilson coefficients of an effective field theory involves minimizing a χ2 function that may contain local minima. Classical optimization algorithms can become trapped in these minima, preven... Read More about Quantum fitting framework applied to effective field theories.

Simulating anti-skyrmions on a lattice (2022)
Journal Article

Magnetic skyrmions are topological spin structures that naturally emerge in magnetic materials. While a vast amount of effort has gone into the study of their properties, their counterpart of opposite topological charge, the anti-skyrmion, has not re...

We study the existence of skyrmions in the presence of all the electroweak degrees of freedom, including a dynamical Higgs boson, with the electroweak symmetry being non-linearly realized in the scalar sector. For this, we use the formulation of the... Read More about Electroweak skyrmions in the HEFT.
