Geometric Stiffness in Interlayer Exciton Condensates
Nishchhal Verma, Daniele Guerci, Raquel Queiroz
Recent experiments have confirmed the presence of interlayer excitons in the ground state of transition metal dichalcogenide (TMD) bilayers. The interlayer excitons are expected to…
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…
Infrared Plasmons Propagate through a Hyperbolic Nodal Metal
Yinming Shao, Aaron J. Sternbach, Brian S. Y. Kim +16
Metals are canonical plasmonic media at infrared and optical wavelengths, allowing one to guide and manipulate light at the nano-scale. A special form of optical waveguiding is aff…
Confined vs. extended Dirac surface states in topological crystalline insulator nanowires
Roni Majlin Skiff, Fernando de Juan, Raquel Queiroz +3
Confining two dimensional Dirac fermions on the surface of topological insulators has remained an outstanding conceptual challenge. Here we show that Dirac fermion confinement is a…
Delocalization Transition of Disordered Axion Insulator
Zhi-Da Song, Biao Lian, Raquel Queiroz +3
The axion insulator is a higher-order topological insulator protected by inversion symmetry. We show that under quenched disorder respecting inversion symmetry {\it on average}, th…
