Signatures of the order parameter of a superconducting adatom layer in magnetic field dependent quasiparticle interference
B. A. Levitan, J. Eid, T. Pereg-Barnea
Experiments have observed superconductivity in atomically-thin metallic layers deposited on semiconducting substrates. As in any superconductor, it is important to determine the st…
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…
Optomechanics with two-phonon driving
B. A. Levitan, A. Metelmann, A. A. Clerk
We consider the physics of an optomechanical cavity subject to coherent two-phonon driving, i.e. degenerate parametric amplification of the mechanical mode. We show that in such a…
Circumferential gap propagation in an anisotropic elastic bacterial sacculus
Swadhin Taneja, Benjamin A. Levitan, Andrew D. Rutenberg
We have modelled stress concentration around small gaps in anisotropic elastic sheets, corresponding to the peptidoglycan sacculus of bacterial cells, under loading corresponding t…
