Phase coherence in one-dimensional superconductivity by power-law hopping

Alejandro M. Lobos, Masaki Tezuka, Antonio M. García-García

In a one-dimensional (1D) superconductor, zero temperature quantum fluctuations destroy phase coherence. Here we put forward a mechanism which can restore phase coherence: power-la…

Soft Superconducting Gap in Semiconductor Majorana Nanowires

So Takei, Benjamin M. Fregoso, Hoi-Yin Hui +2

We theoretically consider the ubiquitous soft gap measured in the tunneling conductance of semiconductor-superconductor hybrid structures, in which recently observed signatures of…

Nonequilibrium probe of paired electron pockets in the underdoped cuprates

G. R. Boyd, So Takei, Victor Galitski

We propose an experimental method that can be used generally to test whether the cuprate pseudogap involves precursor pairing that acts to gap out the Fermi surface. The proposal i…

Topological superconductivity and Majorana fermions in hybrid structures involving cuprate high-T_c superconductors

So Takei, Benjamin M. Fregoso, Victor Galitski +1

The possibility of inducing topological superconductivity with cuprate high-temperature superconductors (HTSC) is studied for various heterostructures. We first consider a ballisti…

Dislocations and the enhancement of superconductivity in odd-parity superconductor SrRuO

Y. A. Ying, N. E. Staley, Y. Xin +6

We report observation of the enhancement of superconductivity near lattice dislocations and the absence of the strengthening of vortex pinning in odd-parity superconductor SrRu…

Andreev Bound states in One Dimensional Topological Superconductor

Xiong-Jun Liu

We study the charge character of the Andreev bound states (ABSs) in one-dimensional topological superconductors with spatial inversion symmetry (SIS) breaking. Despite the absence…

A Josephson junction defect spectrometer for measuring two-level systems

M. J. A. Stoutimore, M. S. Khalil, C. J. Lobb +1

We have fabricated and measured Josephson junction defect spectrometers (JJDSs), which are frequency-tunable, nearly-harmonic oscillators that probe strongly-coupled two-level syst…

Microscopic theory for a ferromagnetic-nanowire/superconductor heterostructure: Transport, fluctuations and topological superconductivity

So Takei, Victor Galitski

Motivated by the recent experiment of Wang et al. [Nature Physics 6, 389 (2010)], who observed a highly unusual transport behavior of ferromagnetic Cobalt nanowires proximity-coupl…
