CANOE: Classically Assisted Non-Orthogonal Eigensolver
Jihyeon Park, Collin C. D. Frink, Matthew Otten
In the early fault-tolerant regime, where quantum resources remain limited, hybrid quantum-classical strategies offer one possible route toward quantum advantage. We introduce CANO…

Topological phase transitions induced by the variation of exchange couplings in graphene
Jihyeon Park, Gun Sang Jeon
We consider a modified graphene model under exchange couplings. Various quantum anomalous phases are known to emerge under uniform or staggered exchange couplings. We introduce the…

Emergence of new topological gapless phases in the modified square-lattice Kitaev model
Jihyeon Park, Gun Sang Jeon
We investigate emergent topological gapless phases in the square-lattice Kitaev model with additional hopping terms. In the presence of nearest-neighbor hopping only, the model is…
