Continuous phase transitions in equilibrium statistical mechanics were successfully
described 50 years ago with the development of the renormalization group framework. This …

The deconfined quantum critical point (DQCP) is an example of phase transitions beyond
the Landau symmetry-breaking paradigm that attracts wide interest. However, its nature has …

A bstract Equilibrium finite temperature observables of a CFT can be described by a local
effective action for background fields—a “thermal effective action”. This effective action …

Defects in conformal field theory (CFT) are of significant theoretical and experimental
importance. The presence of defects theoretically enriches the structure of the CFT, but at …

A bstract We study five-point correlation functions of scalar operators in d-dimensional
conformal field theories. We develop a new approach to computing the five-point conformal …

Conformal field theory (CFT) plays a crucial role in the study of various critical phenomena.
While much attention has been paid to the critical exponents of different universalities, which …

Defects are common in physical systems with boundaries, impurities or extensive
measurements. The interaction between bulk and defect can lead to rich physical …

Novel critical phenomena beyond the Landau-Ginzburg-Wilson paradigm have been long
sought after. Among many candidate scenarios, the deconfined quantum critical point …

A bstract Lorentzian correlators of local operators exhibit surprising singularities in theories
with gravity duals. These are associated with null geodesics in an emergent bulk geometry …

In conformal field theory (CFT), the four-point correlator is a fundamental object that encodes
CFT properties, constrains CFT structures, and connects to the gravitational scattering …
