Coupled wire construction of a topological phase with chiral tricritical Ising edge modes
Chengshu Li, Hiromi Ebisu, Sharmistha Sahoo +2
Tricritical Ising (TCI) phase transition is known to occur in several interacting spin and Majorana fermion models and is described in terms of a supersymmetric conformal field the…

Majorana-Hubbard model on the honeycomb lattice
Chengshu Li, Marcel Franz
Phase diagram of a Hubbard model for Majorana fermions on the honeycomb lattice is explored using a combination of field theory, renormalization group and mean-field arguments, as…

Family of Sachdev-Ye-Kitaev models motivated by experimental considerations
Étienne Lantagne-Hurtubise, Chengshu Li, Marcel Franz
Several condensed-matter platforms have been proposed recently to realize the Sachdev-Ye-Kitaev (SYK) model in their low-energy limit. In these proposed realizations, the character…
