Aging in a mean field elastoplastic model of amorphous solids (2020)
Journal Article

We construct a mean-field elastoplastic description of the dynamics of amorphous solids under arbitrary time-dependent perturbations, building on the work of Lin and Wyart [Phys. Rev.

Possible realization of the Majumdar-Ghosh point in the mineral szenicsite (2022)
Journal Article

The Majumder-Ghosh (MG) point is a point in parameter space for a one-dimensional (1D) frustrated system where α = J 1 / J 2 = 0.5 and the ground state is shown to be a superposition of singlet states. This leads to no magnetic order, instead the gro... Read More about Possible realization of the Majumdar-Ghosh point in the mineral szenicsite.
