Quantum Entanglement of the Sachdev-Ye-Kitaev Models
Chunxiao Liu, Xiao Chen, Leon Balents
The Sachdev-Ye-Kitaev (SYK) model is a quantum mechanical model of fermions interacting with -body random couplings. For , it describes free particles, and is non-chaotic i…
Spin Liquid versus Spin Orbit Coupling on the Triangular Lattice
Jason Iaconis, Chunxiao Liu, Gábor B. Halász +1
In this paper, we explore the relationship between strong spin-orbit coupling and spin liquid physics. We study a very general model on the triangular lattice where spin-orbit coup…
Fracton topological phases from strongly coupled spin chains
Gábor B. Halász, Timothy H. Hsieh, Leon Balents
We provide a new perspective on fracton topological phases, a class of three-dimensional topologically ordered phases with unconventional fractionalized excitations that are either…
A strongly correlated metal built from Sachdev-Ye-Kitaev models
Xue-Yang Song, Chao-Ming Jian, Leon Balents
Strongly correlated metals comprise an enduring puzzle at the heart of condensed matter physics. Commonly a highly renormalized heavy Fermi liquid occurs below a small coherence sc…
Anomalous Hall effect and topological defects in antiferromagnetic Weyl semimetals: MnSn/Ge
Jianpeng Liu, Leon Balents
We theoretically study the interplay between bulk Weyl electrons and magnetic topological defects, including magnetic domains, domain walls, and vortex lines, in the…
