Defects in Wigner crystals: fracton-elasticity duality and vacancy proliferation
Paweł Matus
We develop a low-energy field theory for electrically charged crystals. Using the tools of fracton-elasticity duality, generalized to accommodate the magnetic 1-form symmetry of el…

Quadrupole gauge theory: anti-Higgs mechanism and elastic dual
Aleksander Głódkowski, Paweł Matus, Francisco Peña-Benítez +1
Motivated by the duality between elasticity and fracton gauge theory, we study an extension of the gauge group that includes the quadrupole moment. Remarkably, we find that spontan…
