Bootstrap** smooth conformal defects in Chern-Simons-matter theories
The expectation value of a smooth conformal line defect in a CFT is a conformal invariant functional of its path in space-time. For example, in large N ...

D-Branes for Gauge Theories
D-branes are a very efficient tool to engineer gauge theories and study their properties. They have been instrumental in understanding the...

Anomalous dimensions in hypercubic theories
We perform a comprehensive perturbative study of the operator spectrum in multi-scalar theories with hypercubic global symmetry. This includes...

3d 𝒩 = 2 theories and plumbing graphs: adding matter, gauging, and new dualities
Recently, a large class of 3d 𝒩 = 2 gauge theories with mixed Chern-Simons levels, corresponding to plumbing 3-manifolds, has been identified. In...

Taming the landscape of effective theories
We introduce a generalized notion of finiteness that provides a structural principle for the set of effective theories that can be consistently...

Feynman diagrams in four-dimensional holomorphic theories and the Operatope
We study a class of universal Feynman integrals which appear in four-dimensional holomorphic theories. We recast the integrals as the Fourier...

Phi4tools: compilation of Feynman diagrams for Landau-Ginzburg-Wilson theories
Scalar field theories with quartic interactions are of central interest in the study of second-order phase transitions. For three-dimensional...

A State Space for 3D Euclidean Yang–Mills Theories
It is believed that Euclidean Yang–Mills theories behave like the massless Gaussian free field (GFF) at short distances. This makes it impossible to...

RG flows and symmetry enhancement in five-dimensional Lifshitz gauge theories
Lagrangian gauge theories with a z = 2 Lifshitz scaling provide a family of interacting, asymptotically free five-dimensional field theories. We...

Exotic field theories for (hybrid) fracton phases from imposing constraints in foliated field theory
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...

Partition functions of non-Lagrangian theories from the holomorphic anomaly
The computation of the partition function in certain quantum field theories, such as those of the Argyres-Douglas or Minahan-Nemeschansky type, is...

Soft limits of the wavefunction in exceptional scalar theories
We study the structure of the flat space wavefunctional in scalar field theories with nonlinearly realized symmetries. These symmetries imply soft...

Gauge invariance and finite counterterms in chiral gauge theories
We derive the finite one-loop counterterm required to restore the Ward Identities broken by the regularization scheme in chiral gauge theories. Our...

On the derivation of chiral symmetry breaking in QCD-like theories and S-confining theories
Recent works argue that the pattern of chiral symmetry breaking in QCD-like theories can be derived from supersymmetric (SUSY) QCD with perturbation...

Two loop renormalization of scalar theories using a geometric approach
We derive a general formula for two-loop counterterms in Effective Field Theories (EFTs) using a geometric approach. This formula allows the two-loop...

Field theories on ρ-deformed Minkowski space-time
We study one-loop perturbative properties of scalar field theories on the ρ -Minkowski space. The corresponding star-product, together with the...

On classification of fermionic rational conformal field theories
We systematically study how the integrality of the conformal characters shapes the space of fermionic rational conformal field theories in two...
