Topological Amplification of the Bosonic Kitaev Chain with Non-Uniform Loss

Clément Fortin, Kai Wang, T. Pereg-Barnea

The bosonic Kitaev chain is known to have extraordinary properties distinct from its fermionic counterpart. For example, it exhibits the non-Hermitian skin effect -- its eigenmodes…

Disentangling morphology and conductance in amorphous graphene

Nicolas Gastellu, Ata Madanchi, Lena Simine

Amorphous graphene or amorphous monolayer carbon (AMC) is a family of carbon films that exhibit a surprising sensitivity of electronic conductance to morphology. We combine deep le…

Role of Bath-Induced Many-Body Interactions in the Dissipative Phases of the Su-Schrieffer-Heeger Model

Brett Min, Kartiek Agarwal, Dvira Segal

The Su-Schrieffer-Heeger chain is a prototype example of a symmetry-protected topological insulator. Coupling it non-perturbatively to local thermal environments, either through th…

Observation of Temperature Independent Anomalous Hall Effect in Thin Bismuth from Near Absolute Zero to 300 K Temperature

Oulin Yu, F. Boivin, A. Silberztein +1

We report our discovery of a temperature independent anomalous Hall effect (AHE) from 15 mK to 300 K temperature occurring in a 68 nm thick transport device made out of pure bismut…

Two-dimensional hydrodynamic viscous electron flow in annular Corbino rings

Sujatha Vijayakrishnan, Z. Berkson-Korenberg, J. Mainville +5

The concept of fluidic viscosity is ubiquitous in our everyday life and for it to arise the fluidic medium must necessarily form a continuum where macroscopic properties can emerge…

Magnon transmission across mono-layer graphene junction as a probe of electronic structure

Suman Jyoti De, Sumathi Rao, Ganpathy Murthy

We study magnon transmission across gate-controlled junctions in the manifold of Landau levels in monolayer graphene, in the presence of both spin and valley Zeeman fields. S…

Anomalous Hall Effect in Thin Bismuth

Oulin Yu, Sujatha Vijayakrishnan, R. Allgayer +2

Bismuth, the heaviest of all group V elements with strong spin-orbit coupling, is famously known to exhibit many interesting transport properties, and effects such as Shubnikov-de…

Mass inversion at the Lifshitz transition in monolayer graphene by diffusive, high-density, on-chip, doping

Ayse Melis Aygar, Oliver Durnan, Bahar Molavi +3

Experimental setups for charge transport measurements are typically not compatible with the ultra-high vacuum conditions for chemical doping, limiting the charge carrier density th…
