Organizing transitions and their cascades: Generalized symmetry enforcement in massless flows or Higgs transitions
Yoshiki Fukusumi, Yuma Furuta
We study the role of generalized symmetry in massless renormalization group flows or Higgs transitions. In particular, we revisit the massless renormalization group flows in unitar…
Characterizing gapped phases by smeared boundary conformal field theories: Duality in unusual ordering with spontaneously broken generalized symmetries
Yoshiki Fukusumi, Shuma Nakashiba
We study the classification of the gapped phases or massive renormalization group (RG) flows dual to the massless RG flows under changing the sign of the coupling constants. Wherea…
Boundary critical phenomena in the quantum Ashkin-Teller model
Yifan Liu, Natalia Chepiga, Yoshiki Fukusumi +1
We investigate the boundary critical phenomena of the one-dimensional quantum Ashkin-Teller model using boundary conformal field theory and density matrix renormalization group (DM…
Classifying fusion rules of anyons or SymTFTs: A general algebraic formula for domain wall problems and quantum phase transitions
Yoshiki Fukusumi
We propose a formula for the transformation law of anyons in topologically ordered phases or topological quantum field theories (TQFTs) through a gapped or symmetry-preserving doma…
Generalizing fusion rules by shuffle: Symmetry-based classifications of nonlocal systems constructed from similarity transformations
Yoshiki Fukusumi, Taishi Kawamoto
We study fusion rings, or symmetry topological field theories (SymTFTs), which lie outside the non-negative integer matrix representation (NIM-rep), by combining knowledge from gen…
Generalizing quantum dimensions: Symmetry-based classification of local pseudo-Hermitian systems and the corresponding domain walls
Yoshiki Fukusumi, Taishi Kawamoto
We study conformal field theories (CFTs) and their classifications from a modern perspective based on the abstract algebraic formalism of symmetries or conserved charges, known as…
