On Enriching the Levin-Wen model with Symmetry
Liang Chang, Meng Cheng, Shawn X. Cui +6
Symmetry protected and symmetry enriched topological phases of matter are of great interest in condensed matter physics due to new materials such as topological insulators. The Lev…
Power law violation of the area law in quantum spin chains
Ramis Movassagh, Peter W. Shor
The sub-volume scaling of the entanglement entropy with the system's size, , has been a subject of vigorous study in the last decade [1]. The area law provably holds for gapped…
The Green's Function for the Hückel (Tight Binding) Model
Ramis Movassagh, Gilbert Strang, Yuta Tsuji +1
Applications of the Hückel (tight binding) model are ubiquitous in quantum chemistry and solid state physics. The matrix representation of this model is isomorphic to an unoriented…
Eigenvalue Attraction
Ramis Movassagh
We prove that the complex conjugate (c.c.) eigenvalues of a smoothly varying real matrix attract (Eq. 15). We offer a dynamical perspective on the motion and interaction of the eig…
