The next frontiers for magnetic monopole searches (2025)
Journal Article
Gould, O., Ostrovskiy, I., & Upreti, A. (2025). The next frontiers for magnetic monopole searches. Physical Review D, 111(10), Article 102004. https://doi.org/10.1103/PhysRevD.111.102004

Magnetic monopoles (MMs) are well-motivated hypothetical particles whose discovery would symmetrize Maxwell equations, explain quantization of electric charge, and probe the gauge structure of the unified theory. Recent models predict MMs with low ma... Read More about The next frontiers for magnetic monopole searches.

Nonperturbative test of nucleation calculations for strong phase transitions (2025)
Journal Article

Nucleation rate computations are of broad importance in particle physics and cosmology. Perturbative calculations are often used to compute the nucleation rate Γ, but these are incomplete. We perform nonperturbative lattice simulations of nucleation... Read More about Nonperturbative test of nucleation calculations for strong phase transitions.
