On the Wilson-Fisher fixed point in the limit of integer spacetime dimensions
Bernardo Zan
The Wilson-Fisher fixed point defines a continuous family of interacting conformal field theories in non-integer dimensions. In integer dimensions, it is widely believed to lie in…
Phase Diagram of the Two-Flavor Schwinger Model at Zero Temperature
Ross Dempsey, Igor R. Klebanov, Silviu S. Pufu +2
We examine the phase structure of the two-flavor Schwinger model as a function of the -angle and the two masses, and . In particular, we find interesting effects at $…
Discrete Chiral Symmetry and Mass Shift in Lattice Hamiltonian Approach to Schwinger Model
Ross Dempsey, Igor R. Klebanov, Silviu S. Pufu +1
We revisit the lattice formulation of the Schwinger model using the Kogut-Susskind Hamiltonian approach with staggered fermions. This model, introduced by Banks et al., contains th…
The Prepotential and the Sphere Free Energy
Bernardo Zan, Daniel Z. Freedman, Silviu S. Pufu
We study the mass-deformed sphere free energy of three-dimensional superconformal field theories with holographic duals. Building on previous observations, we con…
The Holographic Contributions to the Sphere Free Energy
Damon J. Binder, Daniel Z. Freedman, Silviu S. Pufu +1
We study which bulk couplings contribute to the free energy of three-dimensional superconformal field theories with holographic duals, potent…
Two-dimensional O(n) models and logarithmic CFTs
Victor Gorbenko, Bernardo Zan
We study O(n)-symmetric two-dimensional conformal field theories (CFTs) for a continuous range of n below two. These CFTs describe the fixed point behavior of self-avoiding loops.…
