Interlayer Coupling and Strain Localization in Small-Twist-Angle Graphene Flakes
Vahid Morovati, Zhiming Xue, Kenneth M. Liechti +1
Twisted bilayer graphene (TBG) exhibits a wide range of intriguing physical properties, such as superconductivity, ferromagnetism, and superlubricity. Depending on the twist angle,…
Quantum Critical Spin-2 Chain with Emergent SU(3) Symmetry
Pochung Chen, Zhi-Long Xue, I. P. McCulloch +3
We study the quantum critical phase of a SU(2) symmetric spin-2 chain obtained from spin-2 bosons in a one-dimensional lattice. We obtain the scaling of the entanglement entropy an…
Dimerized and trimerized phases for spin-2 Bosons in a one-dimensional optical lattice
Pochung Chen, Zhi-Long Xue, I. P. McCulloch +2
We study the phase diagram for spin-2 bosons loaded in a one-dimensional optical lattice. By using non-Abelian density matrix renormalization group (DMRG) method we identify three…
