Effects of Electron Form Factor on Quasiparticle Interference in Twisted Bilayer Graphene
D. -H. -Minh Nguyen, Francisco Guinea, Dario Bercioux
The overlap matrix of electronic energy eigenstates, sometimes referred to as the form factor, determines the quantum geometric tensor of electrons in solids. Here, we show that th…
Chiral edge-state signatures of Berry monopole merging and splitting in a bilayer photonic crystal slab with synthetic momentum
Ngoc Duc Le, D. -H. -Minh Nguyen, Dung Xuan Nguyen +2
Berry monopoles are point degeneracies in parameter space where the Berry curvature emanates radially, analogous to magnetic monopoles. Here, we report the adiabatic merging and sp…
Tunable hyperbolic Landau-level polaritons in charge-neutral graphene nanoribbon metasurfaces
Kateryna Domina, Tetiana Slipchenko, D. -H. -Minh Nguyen +4
Magnetized charge-neutral graphene supports collective hybrid electronic excitations - polaritons - which have quantum origin. In contrast to polaritons in doped graphene, which ar…
Impurity-induced counter skin-effect and linear modes in non-Hermitian systems
Nico G. Leumer, Dario Bercioux
Non-reciprocal lattice systems are among the simplest non-Hermitian systems, exhibiting several key features absent in their Hermitian counterparts. In this study, we investigate t…
Parallel spin transport and holonomy in non-Euclidean curved circuits on a spherical two-dimensional electron gas
E. J. Rodríguez, A. A. Reynoso, J. P. Baltanás +2
The quantum conductance of one-dimensional (1D) circuits built on flat (Euclidean) two-dimensional electron gases (2DEGs) is known to display a symmetric response to the inversion…
Robust zero-energy modes in an electronic higher-order topological insulator: the dimerized Kagome lattice
S. N. Kempkes, M. R. Slot, J. J. van den Broeke +6
Quantum simulators are an essential tool for understanding complex quantum materials. Platforms based on ultracold atoms in optical lattices and photonic devices led the field so f…
