Anomalies from correlation functions in defect conformal field theory
Christopher P. Herzog, Itamar Shamir
In previous work, we showed that an anomaly in the one point function of marginal operators is related by the Wess-Zumino condition to the Euler density anomaly on a two dimensiona…
How a-type anomalies can depend on marginal couplings
Christopher P. Herzog, Itamar Shamir
Even dimensional defects and boundaries in conformal field theory support type anomalies on their world-volume. We show that the one-point functions of marginal operators, in t…
On Marginal Operators in Boundary Conformal Field Theory
Christopher P. Herzog, Itamar Shamir
The presence of a boundary (or defect) in a conformal field theory allows one to generalize the notion of an exactly marginal deformation. Without a boundary, one must find an oper…
Superconformal Models for Graphene and Boundary Central Charges
Christopher P. Herzog, Kuo-Wei Huang, Itamar Shamir +1
In the context of boundary conformal field theory, we investigate whether the boundary trace anomaly can depend on marginal directions in the presence of supersymmetry. Recently, i…
Defect multiplets of N=1 supersymmetry in 4d
N. Drukker, I. Shamir, C. Vergu
Any 4d theory possessing supersymmetry admits a so called -multiplet, containing the conserved energy-momentum tensor and supercurrent. When a defect i…
The energy-momentum multiplet of supersymmetric defect field theories
Nadav Drukker, Dario Martelli, Itamar Shamir
Defects in field theories break translation invariance, resulting in the non-conservation of the energy-momentum tensor in the directions normal to the defect. This violation is kn…
Quantum Electrodynamics in d=3 from the epsilon-expansion
Lorenzo Di Pietro, Zohar Komargodski, Itamar Shamir +1
We study Quantum Electrodynamics in d=3 (QED_3) coupled to N_f flavors of fermions. The theory flows to an IR fixed point for N_f larger than some critical number N_f^c. For N_f<=…
On Supersymmetry, Boundary Actions and Brane Charges
Lorenzo Di Pietro, Nizan Klinghoffer, Itamar Shamir
Supersymmetry transformations change the Lagrangian into a total derivative . On manifolds with boundaries the total derivativ…
The Chiral Multiplet on and Supersymmetric Localization
Cyril Closset, Itamar Shamir
We compute the supersymmetric partition function of an chiral multiplet coupled to an external Abelian gauge field on complex manifolds with topolo…
On O(N_c) d=3 N=2 supersymmetric QCD Theories
Ofer Aharony, Itamar Shamir
We study three dimensional N=2 supersymmetric QCD theories with O(N_c) gauge groups and with N_f chiral multiplets in the vector representation. We argue that for N_f < N_c-2 there…
Near-horizon solutions for D3-branes ending on 5-branes
Ofer Aharony, Leon Berdichevsky, Micha Berkooz +1
We construct the type IIB supergravity solutions describing D3-branes ending on 5-branes, in the near-horizon limit of the D3-branes. Our solutions are holographically dual to the…
