Magnetism and superconductivity in doped triangular-lattice Mott insulators
Kun Woo Kim, T. Pereg-Barnea
Inspired by recent advances in the fabrication of surface superlattices, and in particular the triangular lattice made of tin (Sn) atoms on silicon, we study an extended Hubbard mo…
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…
Dynamical approach to improving Majorana qubits and distinguishing them from trivial bound states
Brett Min, Bastien Fajardo, T. Pereg-Barnea +1
We study a series of dynamical protocols which involve periodically driving a quantum dot coupled to a putative nanowire hosting Majorana zero modes (MZMs) to i) reduce the hybridi…
Berry Phase in Cuprate Superconductors
N. Doiron-Leyraud, T. Szkopek, T. Pereg-Barnea +2
Geometrical Berry phase is recognized as having profound implications for the properties of electronic systems. Over the last decade, Berry phase has been essential to our understa…
Origin of the T enhancement in heterostructure cuprate superconductors
Doron L. Bergman, Tami Pereg-Barnea
Recent experiments on heterostructures composed of two or more films of cuprate superconductors of different oxygen doping levels\cite{Yuli,Gozar} have shown a remarkable T enh…
Vortex as a probe - suggested measurement of the order parameter structure in iron-based superconductors
Eugeniu Plamadeala, T. Pereg-Barnea, Gil Refael
Impurities, inevitably present in all samples, induce elastic transitions between quasiparticle states on the contours of constant energy. These transitions may be seen in Fourier…
