Surface theory of a second-order topological insulator beyond the Dirac approximation
B. A. Levitan, L. Goutte, T. Pereg-Barnea
We study the surface states and chiral hinge states of a 3D second-order topological insulator in the presence of an external magnetic gauge field. Surfaces pierced by flux host La…

Second-order topological insulator under strong magnetic field: Landau levels, Zeeman effect, and magnetotransport
B. A. Levitan, T. Pereg-Barnea
We study a three-dimensional chiral second order topological insulator (SOTI) subject to a magnetic field. Via its gauge field, the applied magnetic field influences the electronic…

High-efficiency measurement of an artificial atom embedded in a parametric amplifier
A. Eddins, J. M. Kreikebaum, D. M. Toyli +7
A crucial limit to measurement efficiencies of superconducting circuits comes from losses involved when coupling to an external quantum amplifier. Here, we realize a device circumv…
