SO (5) Deconfined Phase Transition under the Fuzzy-Sphere Microscope: Approximate Conformal Symmetry, Pseudo-Criticality, and Operator Spectrum
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 …

Studying the 3d Ising surface CFTs on the fuzzy sphere
Boundaries not only are fundamental elements in nearly all realistic physical systems, but
also greatly enrich the structure of quantum field theories. In this paper, we demonstrate that …

Ising BCFT from Fuzzy Hemisphere
M Dedushenko - arxiv preprint arxiv:2407.15948, 2024 - arxiv.org
We extend the recently introduced fuzzy sphere technique for the 3d Ising CFT to the case of
boundary CFT (BCFT) using the fuzzy hemisphere. This allows to study conformal boundary …
