Putting a new spin on the incommensurate Kekulé spiral: from spin-valley locking and collective modes to fermiology and implications for superconductivity
Ziwei Wang, Glenn Wagner, Yves H. Kwan +3
We revisit the global phase diagram of magic-angle twisted bilayer and [symmetric] trilayer graphene (MA-TBG/TSTG) in light of recent scanning tunneling microscopy (STM) measuremen…

Nearfield Vortex Dynamics of Supercell Bloch Modes
Xiaona Ye, Guangfeng Wang, Xiaoyang Duan +7
Densely arranged optical vortices are natural solutions of high-symmetry Bloch modes in photonic crystals. However, strict symmetry constraints limit the potential spatial configur…

A Closed Band-Projected Density Algebra Must be Girvin-MacDonald-Platzman
Ziwei Wang, Steven H. Simon
The band-projected density operators in a Landau level obey the Girvin-MacDonald-Platzman (GMP) algebra, and a large amount of effort in the study of fractional Chern insulators ha…
