Author Correction: Solving conformal defects in 3D conformal field theory using fuzzy sphere regularization - Nature Communications
Correction to: Nature Communications https://doi.org/10.1038/s41467-024-47978-y, published online 30 April 2024 The original version of this Article contained an error in Eq. 9, which was missing a factor of 2 under the square root sign on the left-hand side.
Reclaiming the Lost Conformality in a Non-Hermitian Quantum 5-State Potts Model
Conformal symmetry, emerging at critical points, can be lost when renormalization group fixed points collide. Recently, it was proposed that after collisions, real fixed points transition into the complex plane, becoming complex fixed points described by complex conformal field theories (CFTs). Although this idea is compelling, directly demonstrating such complex conformal fixed points in microscopic models remains highly demanding.
SO(5) Deconfined Phase Transition under the Fuzzy-Sphere Microscope: Approximate Conformal Symmetry, Pseudo-Criticality, and Operator Spectrum
Popular Summary Quantum phase transitions, wherein quantum fluctuations at zero temperature change the state of matter, are a central topic in modern condensed matter physics. Among such transitions, deconfined quantum critical points (DQCPs) are particularly intriguing: Characterized by emergent symmetries and topological characteristics, they cannot be described by conventional phase-transition frameworks.
