TL;DR: In this article, the edge states at the boundary of strongly interacting symmetry protected topological (SPT) states, when the bulk is driven to a disorder-order phase transition, were studied.
Physics of symmetry protected topological phases involving higher symmetries and its applications
TL;DR: In this article, the boundary properties of symmetry-protected topological phases that involve 1-form symmetries from one spatial dimension to four spatial dimensions were discussed. And the connection between SPT states and condensed-matter systems such as quantum dimer models at one lower dimension was discussed.

Orbital order and possible non-Fermi liquid in moiré systems
TL;DR: In this paper, the authors studied three different orbital orders that potentially can happen in Moire systems: (1) the nematic order, (2) the valley polarization, and (3) the "compass order".

Continuous N\'{e}el-VBS Quantum Phase Transition in Non-Local one-dimensional systems with SO(3) Symmetry
TL;DR: In this paper, the edge states at the boundary of strongly interacting symmetry protected topological (SPT) states, when the bulk is driven to a disorder-order phase transition, were studied.
Topological edge and interface states at bulk disorder-to-order quantum critical points
TL;DR: In this paper, the authors studied the interplay between two nontrivial boundary effects: (1) the two-dimensional edge states of three-dimensional strongly interacting bosonic symmetry-protected topological states, and (2) the boundary fluctuations of bulk disorder-to-order phase transitions.
