A search for correlation-induced adiabatic paths between distinct topological insulators
Johannes S. Hofmann, Fakher F. Assaad, Raquel Queiroz +1
Correlations in topological states of matter provide a rich phenomenology, including a reduction in the topological classification of the interacting system compared to its non-int…
Cascade of Phase Transitions and Dirac Revivals in Magic Angle Graphene
Uri Zondiner, Asaf Rozen, Daniel Rodan-Legrain +10
Twisted bilayer graphene near the magic angle exhibits remarkably rich electron correlation physics, displaying insulating, magnetic, and superconducting phases. Here, using measur…
Experimental characterization of fragile topology in an acoustic metamaterial
Valerio Peri, Zhi-Da Song, Marc Serra-Garcia +7
Symmetries crucially underlie the classification of topological phases of matter. Most materials, both natural as well as architectured, possess crystalline symmetries. Recent theo…
Modular Arithmetic with Nodal Lines: Drumhead Surface States in ZrSiTe
Lukas Muechler, Andreas Topp, Raquel Queiroz +5
We study the electronic structure of the nodal line semimetal ZrSiTe both experimentally and theoretically. We find two different surface states in ZrSiTe - topological drumhead su…
Boundary-obstructed topological phases
Eslam Khalaf, Wladimir A. Benalcazar, Taylor L. Hughes +1
Symmetry protected topological (SPT) phases are gapped phases of matter that cannot be deformed to a trivial phase without breaking the symmetry or closing the bulk gap. Here, we i…
Visualizing Poiseuille flow of hydrodynamic electrons
Joseph A. Sulpizio, Lior Ella, Asaf Rozen +12
Hydrodynamics is a general description for the flow of a fluid, and is expected to hold even for fundamental particles such as electrons when inter-particle interactions dominate.…
Unified description of the classical Hall viscosity
Tobias Holder, Raquel Queiroz, Ady Stern
In absence of time-reversal symmetry, viscous electron flow hosts a number of interesting phenomena, of which we focus here on the Hall viscosity. Taking a step beyond the hydrodyn…
Resolving the Topological Classification of Bismuth with Topological Defects
Abhay Kumar Nayak, Jonathan Reiner, Raquel Queiroz +6
Bulk boundary correspondence in topological materials allows to study their bulk topology through the investigation of their topological boundary modes. However, for classes that s…
Ballistic and hydrodynamic magnetotransport in narrow channels
Tobias Holder, Raquel Queiroz, Thomas Scaffidi +6
An increasing number of low carrier density materials exhibit a surprisingly large transport mean free path due to inefficient momentum relaxation. Consequently, charge transport i…
