Symmetry-Protected Topological Phases in the Triangular Majorana-Hubbard Ladder
Will Holdhusen, Alberto Nocera, Jian-Xin Zhu +1
We uncover a family of symmetry-protected topological phases in a model of interacting Majorana fermions on triangular-lattice ladders. Included among these phases is one in which…

Soliton-antisoliton pairs in the supersymmetric gapped phase of an interacting Majorana chain
Alberto Nocera, Mobin Shakeri, Armin Rahmani +1
A strongly interacting chain of Majorana fermions realizes the supersymmetric tricritical Ising phase, with supersymmetry (SUSY) extending into a symmetry-broken ordered phase adja…

Frustrated S = 1/2 Chains in One-Dimensional Correlated Metal Ti4MnBi2
X. Y. Li, A. Nocera, K. Foyevtsova +7
Electronic correlations lead to heavy quasiparticles in three-dimensional (3D) metals, and their collapse can destabilize magnetic moments. It is an open question whether there is…
