HIGHLIGHTS
- who: James D. Watson from the Department of Computer Science, University College London, London, UK have published the Article: Uncomputably complex renormalisation group flows, in the Journal: (JOURNAL) of 22/Nov/2022
- what: The authors develop an RG scheme which 3 shows the RG scheme for the quantum part. The authors have shown that a qualitatively new type of RG flow occurs in many-body Hamiltonians with undecidable spectral gap. The authors show that under this RG construction, the Hamiltonian flows toward one of two RG fixed points: either a gapped Ising-like Hamiltonian or . . .
