Probing embedded topological modes in bulk-like GeTe-SbTe heterostructures
Hisao Nakamura, Johannes Hofmann, Nobuki Inoue +5
The interface between topological and normal insulators hosts metallic states that appear due to the change in band topology. While these topological states at a surface, i.e., a t…
Type Ia supernovae from dark matter core collapse
Ryan Janish, Vijay Narayan, Paul Riggins
Dark matter (DM) which sufficiently heats a local region in a white dwarf will trigger runaway fusion, igniting a type Ia supernova (SN). In a companion paper, this instability was…
Axion production and detection with superconducting RF cavities
Ryan Janish, Vijay Narayan, Surjeet Rajendran +1
We propose a novel design of a laboratory search for axions based on photon regeneration with superconducting RF cavities. Our particular setup uses a toroid as a region of confine…
Long-lived non-equilibrium superconductivity in a non-centrosymmetric Rashba semiconductor
V. Narayan, P. C. Verpoort, J. R. A. Dann +8
We report non-equilibrium magnetodynamics in the Rashba-superconductor GeTe, which lacks inversion symmetry in the bulk. We find that at low temperature the system exhibits a non-e…
Au-Ge alloys for wide-range low-temperature on-chip thermometry
J. R. A. Dann, P. C. Verpoort, J. Ferreira de Oliveira +4
We present results of a Au-Ge alloy that is useful as a resistance-based thermometer from room temperature down to at least \SI{0.2}{\kelvin}. Over a wide range, the electrical res…
Thickness dependence of electron-electron interactions in topological p-n junctions
Dirk Backes, Danhong Huang, Rhodri Mansell +7
Electron-electron interactions in topological p-n junctions consisting of vertically stacked topological insulators are investigated. n-type Bi2Te3 and p-type Sb2Te3 of varying rel…
