Impurities in Schrödinger field theories and s-wave resonance
Avia Raviv-Moshe, Siwei Zhong
We study point impurities in non-relativistic quantum field theories, with a focus on scale-invariant fixed points. We establish the framework of conformal defects in Schrödinger f…
Phases of Wilson Lines: Conformality and Screening
Ofer Aharony, Gabriel Cuomo, Zohar Komargodski +2
We study the rich dynamics resulting from introducing static charged particles (Wilson lines) in 2+1 and 3+1 dimensional gauge theories. Depending on the charges of the external pa…
Phases of Surface Defects in Scalar Field Theories
Avia Raviv-Moshe, Siwei Zhong
We study mass-type surface defects in a free scalar and Wilson-Fisher (WF) theories. We obtain exact results for the free scalar defect, including its RG flow and defect Wey…
Phases of Wilson Lines in Conformal Field Theories
Ofer Aharony, Gabriel Cuomo, Zohar Komargodski +2
We study the low-energy limit of Wilson lines (charged impurities) in conformal gauge theories in 2+1 and 3+1 dimensions. As a function of the representation of the Wilson line, ce…
Spin Impurities, Wilson Lines and Semiclassics
Gabriel Cuomo, Zohar Komargodski, Márk Mezei +1
We consider line defects with large quantum numbers in conformal field theories. First, we consider spin impurities, both for a free scalar triplet and in the Wilson-Fisher …
Boundary Conformal Field Theory at Large Charge
Gabriel Cuomo, Márk Mezei, Avia Raviv-Moshe
We study operators with large internal charge in boundary conformal field theories (BCFTs) with internal symmetries. Using the state-operator correspondence and the existence of a…
Renormalization Group Flows on Line Defects
Gabriel Cuomo, Zohar Komargodski, Avia Raviv-Moshe
We consider line defects in d-dimensional Conformal Field Theories (CFTs). The ambient CFT places nontrivial constraints on Renormalization Group (RG) flows on such line defects. W…
Spontaneously Broken Boosts in CFTs
Zohar Komargodski, Márk Mezei, Sridip Pal +1
Conformal Field Theories (CFTs) have rich dynamics in heavy states. We describe the constraints due to spontaneously broken boost and dilatation symmetries in such states. The spon…
Holomorphic Structure and Quantum Critical Points in Supersymmetric Lifshitz Field Theories
Igal Arav, Yaron Oz, Avia Raviv-Moshe
We construct supersymmetric Lifshitz field theories with four real supercharges in a general number of space dimensions. The theories consist of complex bosons and fermions and exh…
On Non-Relativistic Supersymmetry and its Spontaneous Breaking
Adiel Meyer, Yaron Oz, Avia Raviv-Moshe
We study non-relativistic supersymmetric field theories in diverse dimensions. The theories consist of scalars and fermions and possess two, four or eight real supercharges. We ana…
Lifshitz Anomalies, Ward Identities and Split Dimensional Regularization
Igal Arav, Yaron Oz, Avia Raviv-Moshe
We analyze the structure of the stress-energy tensor correlation functions in Lifshitz field theories and construct the corresponding anomalous Ward identities. We develop a framew…
On Supersymmetric Lifshitz Field Theories
Shira Chapman, Yaron Oz, Avia Raviv-Moshe
We consider field theories that exhibit a supersymmetric Lifshitz scaling with two real supercharges. The theories can be formulated in the language of stochastic quantization. We…
