Higher-form Gauge Symmetries in Multipole Topological Phases
Oleg Dubinkin, Alex Rasmussen, Taylor L. Hughes
In this article we study field-theoretical aspects of multipolar topological insulators. Previous research has shown that such systems naturally couple to higher-rank tensor gauge…
Entanglement Signatures of Multipolar Higher Order Topological Phases
Oleg Dubinkin, Taylor L. Hughes
We propose a procedure that characterizes free-fermion or interacting multipolar higher-order topological phases via their bulk entanglement structure. To this end, we construct ne…
Lieb Schultz Mattis-Type Theorems and Other Non-perturbative Results for Strongly Correlated Systems with Conserved Dipole Moments
Oleg Dubinkin, Julian May-Mann, Taylor L. Hughes
Non-perturbative constraints on many body physics--such as the famous Lieb-Schultz-Mattis theorem--are valuable tools for studying strongly correlated systems. To this end, we pres…
Theory of Dipole Insulators
Oleg Dubinkin, Julian May-Mann, Taylor L. Hughes
Insulating systems are characterized by their insensitivity to twisted boundary conditions as quantified by the charge stiffness and charge localization length. The latter quantity…
Higher Order Bosonic Topological Phases in Spin Models
Oleg Dubinkin, Taylor L. Hughes
We discuss an extension of higher order topological phases to include bosonic systems. We present two spin models for a second-order topological phase protected by a global $\mathb…
