The quantum geometric origin of capacitance in insulators
Ilia Komissarov, Tobias Holder, Raquel Queiroz
In band insulators, where the Fermi surface is absent, adiabatic transport is allowed only due to the geometry of the Hilbert space. By driving the system at a small but finite fre…

Chiral limit and origin of topological flat bands in twisted transition metal dichalcogenide homobilayers
Valentin Crépel, Nicolas Regnault, Raquel Queiroz
The observation of zero field fractional quantum Hall analogs in twisted transition metal dichalcogenides (TMDs) asks for a deeper understanding of what mechanisms lead to topologi…

Anderson Critical Metal Phase in Trivial States Protected by Average Magnetic Crystalline Symmetry
Fa-Jie Wang, Zhen-Yu Xiao, Raquel Queiroz +3
Transitions between distinct obstructed atomic insulators (OAIs) protected by crystalline symmetries, where electrons form molecular orbitals centering away from the atom positions…
