Robust Flat Bands with Tunable Energies in Honeycomb Superlattices
Zihao Qi, Eric Bobrow, Yi Li
Flat bands in lattice models have provided useful platforms for studying strong correlation and topological physics. Recently, honeycomb superlattices have been shown to host flat…
Hund's coupling-assisted ferromagnetic percolation transition in a multiorbital flat band
Eric Bobrow, Junjia Zhang, Yi Li
By connecting Hund's physics with flat band physics, we establish an exact result for studying ferromagnetism in a multiorbital system. We consider a two-layer model consisting of…
Topologically Obstructed Superconducting Order
Canon Sun, Yi Li
We propose a class of topological superconductivity in which the pairing order is topologically obstructed in a three-dimensional time-reversal invariant system. Whe…
Berry Phase Enforced Spinor Pairing
Yi Li
Pairing symmetry plays a central role in the study of superconductivity. It is usually characterized by integer partial-waves, for example, -, -, -waves. In this article,…
