Shiba duality and -altermagnetism: Pairing and charge orders in bipartite attractive Hubbard models
Yu-Ping Lin
We show that Shiba duality maps the altermagnetic principle of momentum-dependent band splitting from spin to -pseudospin, defining -altermagnetism (-ALM) as a Bogoliubov-…
Ultrafast optical control of charge orders in kagome metals
Yu-Ping Lin, Vidya Madhavan, Joel E. Moore
We show that ultrafast optical pump pulses provide effective control over charge orders in the kagome metals VSb with K, Rb, and Cs. Starting from the real charge d…
Higher-order topological insulators from charge bond orders on hexagonal lattices: A hint to kagome metals
Yu-Ping Lin
We show that unconventional boundary phenomena occur in the charge bond orders on the hexagonal lattices. At the Van Hove singularity with three nesting momenta, orders c…
Complex charge density waves at Van Hove singularity on hexagonal lattices: Haldane-model phase diagram and potential realization in kagome metals
Yu-Ping Lin, Rahul M. Nandkishore
We investigate how the real and imaginary charge density waves interplay at the Van Hove singularity on the hexagonal lattices. A phenomenological analysis indicates the formation…
Parquet renormalization group analysis of weak-coupling instabilities with multiple high-order Van Hove points inside the Brillouin zone
Yu-Ping Lin, Rahul M. Nandkishore
We analyze the weak-coupling instabilities that may arise when multiple high-order Van Hove points are present inside the Brillouin zone. The model we consider is inspired by twist…
Superconductor versus insulator in twisted bilayer graphene
Yang-Zhi Chou, Yu-Ping Lin, Sankar Das Sarma +1
We present a simple model that we believe captures the key aspects of the competition between superconducting and insulating states in twisted bilayer graphene. Within this model,…
