Wiedemann-Franz law and Fermi liquids
Ali Lavasani, Daniel Bulmash, Sankar Das Sarma
We consider in depth the applicability of the Wiedemann-Franz (WF) law, namely that the electronic thermal conductivity () is proportional to the product of the absolute tempera…
Braiding and Gapped Boundaries in Fracton Topological Phases
Daniel Bulmash, Thomas Iadecola
We study gapped boundaries of Abelian type-I fracton systems in three spatial dimensions. Using the X-cube model as our motivating example, we give a conjecture, with partial proof…
Generalized Gauge Field Theories and Fractal Dynamics
Daniel Bulmash, Maissam Barkeshli
We present a theoretical framework for a class of generalized gauge effective field theories. These theories are defined by specifying geometric patterns of charge configura…
The Higgs Mechanism in Higher-Rank Symmetric Gauge Theories
Daniel Bulmash, Maissam Barkeshli
We use the Higgs mechanism to investigate connections between higher-rank symmetric gauge theories and gapped fracton phases. We define two classes of rank-2 symmetric $U(1)…
