Sp(4,Z) actions on 3d U(1)^2 symmetric theories: Order-five duality and bilayer quantum Hall hierarchies
Yasin F. Alam, Andreas Karch, Da-Chuan Lu +1
The electromagnetic duality of 4d Maxwell theory induces theory-generating operations on 3d theories with global symmetry. For theories with $U(1…
One-point functions in 2D and 4D SUSY Janus
Andreas Karch, Ainesh Sanyal, Ryan C. Spieler +1
We calculate one-point functions of the marginal operators dual to the space-varying dilaton in 4D and 2D holographic Janus interfaces, extending the results of \cite{Clark_2005}.…
Exploring two dimensional invariant phases with time reversal symmetry and their transitions with topological operations
Ryan C. Spieler
We use various topological operations to systematically study phase transitions between theories with and time reversal symmetry in two spacetime dimensions. The pha…
Critical theories connecting gapped phases with symmetry from the duality web
Andreas Karch, Ryan C. Spieler
We use the ideas behind the duality web to construct numerous conformal field theories mediating the phase transitions between various symmetry broken and topological phases. In pa…
Non-Invertible Duality Interfaces in Field Theories with Exotic Symmetries
Ryan C. Spieler
In recent years, the concept of global symmetry has generalized considerably. Two dramatic examples of this generalization are the exotic symmetries that govern theories with fract…
Exotic Field Theories for (Hybrid) Fracton Phases from Imposing Constraints in Foliated Field Theory
Ryan C. Spieler
Fracton phases of matter are gapped phases of matter that, by dint of their sensitivity to UV data, demand non-standard quantum field theories to describe them in the IR. Two such…
Boundary theory of the X-cube model in the continuum
Zhu-Xi Luo, Ryan C. Spieler, Hao-Yu Sun +1
We study the boundary theory of the X-cube model using a continuum perspective, from which the exchange statistics of a subset of bulk excitations can be recovered.…
