Anomalous Symmetries End at the Boundary
Ryan Thorngren, Yifan Wang
A global symmetry of a quantum field theory is said to have an 't Hooft anomaly if it cannot be promoted to a local symmetry of a gauged theory. In this paper, we show that the ano…
Surface Defect, Anomalies and -Extremization
Yifan Wang
Quantum field theories (QFT) in the presence of defects exhibit new types of anomalies which play an important role in constraining the defect dynamics and defect renormalization g…
Classifying Superconformal Defects in Diverse Dimensions Part I: Superconformal Lines
Nathan B. Agmon, Yifan Wang
We initiate the classification of unitary superconformal defects in unitary superconformal field theories (SCFT) of diverse spacetime dimensions . Our method explor…
New Modular Invariants in Super-Yang-Mills Theory
Shai M. Chester, Michael B. Green, Silviu S. Pufu +2
We study modular invariants arising in the four-point functions of the stress tensor multiplet operators of the super-Yang-Mills theory, in the limit where $…
From Super-Yang-Mills on to bosonic Yang-Mills on
Yifan Wang
We study the four-dimensional super-Yang-Mills (SYM) theory on the unorientable spacetime manifold . Using supersymmetric localization, we find that…
Non-perturbative Defect One-Point Functions in Planar Super-Yang-Mills
Shota Komatsu, Yifan Wang
The four dimensional super-Yang-Mills (SYM) theory exhibits rich dynamics in the presence of codimension-one conformal defects. The new structure constants of the e…
Twist Gap and Global Symmetry in Two Dimensions
Nathan Benjamin, Hirosi Ooguri, Shu-Heng Shao +1
We show that every compact, unitary two-dimensional CFT with an abelian conserved current has vanishing twist gap for charged primary fields with respect to the $\mathfrak{u}(1)\ti…
Taming Defects in Super-Yang-Mills
Yifan Wang
We study correlation functions involving extended defect operators in the four-dimensional super-Yang-Mills (SYM). The main tool is supersymmetric localization with re…
Gravitational-Wave Implications for the Parity Symmetry of Gravity at GeV Scale
Yi-Fan Wang, Rui Niu, Tao Zhu +1
Einstein's general relativity, as the most successful theory of gravity, is one of the cornerstones of modern physics. However, the experimental tests for gravity in the high energ…
