Research
I was previously interested in physics beyond the standard model. Currently, I study the nonperturbative
dynamics of general quantum field theories, using a variety of tools, from supersymmetry, branes, and
dualities, to lattice field theory and Monte-Carlo simulations. My most recent publications:
“Metamorphosis of fractional instantons on a twisted four-torus with a double-trace deformation: a numerical study”
with Benjamin Dobozy, arxiv:2606.22078[hep-th]
“D-branes and fractional instantons on a twisted four-torus: the moduli space as an N=2 supersymmetric Higgs branch”
“Mass-deformed Super Yang-Mills theory on the four-torus: sum over twisted sectors, theta-angle, and CP-violation”
with Mohamed Anber, arxiv:2509.00157[hep-th]
