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 $SL (2, Z)$ electromagnetic duality of 4d Maxwell theory induces theory-generating operations on 3d theories with $U (1)$ 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 the one-point functions of the marginal operator $L^{'}$ dual to the space-varying dilaton in 4D and 2D holographic Janus interfaces, extending results in arXiv…

Exploring two dimensional $Z_{2}$ 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 $Z_{2}$ and time reversal symmetry in two spacetime dimensions. The pha…

Critical theories connecting gapped phases with $Z_{2} \times Z_{2}$ 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…
