Flat bands and band touching from real-space topology in hyperbolic lattices
Tomáš Bzdušek, Joseph Maciejko
Motivated by the recent experimental realizations of hyperbolic lattices in circuit quantum electrodynamics and in classical electric-circuit networks, we study flat bands and band…
Hyperbolic Matter in Electrical Circuits with Tunable Complex Phases
Anffany Chen, Hauke Brand, Tobias Helbig +11
Curved spaces play a fundamental role in many areas of modern physics, from cosmological length scales to subatomic structures related to quantum information and quantum gravity. I…
Hyperbolic Topological Band Insulators
David M. Urwyler, Patrick M. Lenggenhager, Igor Boettcher +3
Recently, hyperbolic lattices that tile the negatively curved hyperbolic plane emerged as a new paradigm of synthetic matter, and their energy levels were characterized by a band s…
Triple nodal points characterized by their nodal-line structure in all magnetic space groups
Patrick M. Lenggenhager, Xiaoxiong Liu, Titus Neupert +1
We analyze triply degenerate nodal points [or triple points (TPs) for short] in energy bands of crystalline solids. Specifically, we focus on spinless band structures, i.e., when s…
