Defect mediated quantum melting of charge ordered insulators
Abijith Krishnan, Ajesh Kumar, T. Senthil
Two-dimensional (2d) electronic systems on a lattice at fractional filling exhibit a competition between charge ordered insulators, called Wigner-Mott insulators (WMIs), a…
Unnecessary quantum criticality in kagome magnets
Yunchao Zhang, Xue-Yang Song, T. Senthil
Algebraic/Dirac spin liquids (DSLs) are a class of critical quantum ground states that do not have a quasi-particle description. DSLs and related spin liquid phases often arise in…
Ordering the topological order in the fractional quantum Hall effect
Meng Cheng, Seth Musser, Amir Raz +2
We discuss the possible topological order/topological quantum field theory of different quantum Hall systems. Given the value of the Hall conductivity, we constrain the global symm…
Higgs-mode electromagnon in the spin-spiral multiferroic CuBr
Bryan T. Fichera, Ajesh Kumar, Baiqing Lv +8
Below a continuous symmetry breaking phase transition, the relevant collective excitations are due to longitudinal and transverse fluctuations of the order parameter, which are ref…
Faithful Tight-binding Models and Fragile Topology of Magic-angle Bilayer Graphene
Hoi Chun Po, Liujun Zou, T. Senthil +1
Correlated insulators and superconductivity have been observed in "magic-angle" twisted bilayer graphene, when the nearly flat bands close to neutrality are partially filled. While…
