Entanglement Entropy as a Portal to the Physics of Quantum Spin Liquids
Tarun Grover, Yi Zhang, Ashvin Vishwanath
Quantum Spin Liquids (QSLs) are phases of interacting spins that do not order even at the absolute zero temperature, making it impossible to characterize them by a local order para…
Spin Orbit Magnetism and Unconventional Superconductivity
Yi Zhang, Kevin S. Bedell
We find an exotic spin excitation in a magnetically ordered system with spin orbit magnetism in 2D, where the order parameter has a net spin current and no net magnetization. Start…
Establishing non-Abelian topological order in Gutzwiller projected Chern insulators via Entanglement Entropy and Modular S-matrix
Yi Zhang, Ashvin Vishwanath
We use entanglement entropy signatures to establish non-Abelian topological order in projected Chern-insulator wavefunctions. The simplest instance is obtained by Gutzwiller projec…
Entanglement entropy of critical spin liquids
Yi Zhang, Tarun Grover, Ashvin Vishwanath
Quantum spin liquids are phases of matter whose internal structure is not captured by a local order parameter. Particularly intriguing are critical spin liquids, where strongly int…
