Determining the superconducting order parameter of UPt using scanning tunneling microscopy
Rebecca Bisset, Luke C. Rhodes, Hugo Decitre +5
Superconductivity, a state in which electrical currents can flow without resistance, occurs because of pairing of electrons into quasiparticles with integer spin . In practicall…
Kinetic stabilization of 1D surface states near twin boundaries in noncentrosymmetric BiPd
Chi Ming Yim, Christopher Trainer, Ana Maldonado +4
The search for one-dimensional (1D) topologically-protected electronic states has become an important research goal for condensed matter physics owing to their potential use in spi…
Observation of a well-defined hybridization gap and in-gap states on the SmB6 (001) surface
Zhixiang Sun, Ana Maldonado, Wendel S. Paz +6
The rise of topology in condensed matter physics has generated strong interest in identifying novel quantum materials in which topological protection is driven by electronic correl…
Elastic measurements of amorphous silicon films at mK temperatures
Andrew Fefferman, Ana Maldonado, Eddy Collin +3
The low temperature properties of glass are distinct from those of crystals due to the presence of poorly understood low-energy excitations. The tunneling model proposes that these…
Observation of Dirac surface states in the noncentrosymmetric superconductor BiPd
H. M. Benia, E. Rampi, C. Trainer +12
Materials with strong spin-orbit coupling (SOC) have in recent years become a subject of intense research due to their potential applications in spintronics and quantum information…
Superconducting gap and vortex lattice of the heavy fermion compound CeCu_2Si_2
Mostafa Enayat, Zhixiang Sun, Ana Maldonado +6
The order parameter and pairing mechanism for superconductivity in heavy fermion compounds are still poorly understood. Scanning tunneling microscopy and spectroscopy at ultra-low…
Dirac Surface States and Nature of Superconductivity in Noncentrosymmetric BiPd
Zhixiang Sun, Mostafa Enayat, Ana Maldonado +6
In non-magnetic bulk materials, inversion symmetry protects the spin degeneracy. If the bulk crystal structure lacks a centre of inversion, however, spin-orbit interactions lift th…
Supercurrent on a vortex core in 2H-NbSe: current driven scanning tunneling spectroscopy
A. Maldonado, S. Vieira, H. Suderow
We report current driven scanning tunneling spectroscopy (CDSTS) measurements at very low temperatures on vortices in 2H-NbSe2. We find that a current produces an increase of the d…
Temperature dependent tunneling spectroscopy in the heavy fermion CeRu2Si2 and in the antiferromagnet CeRh2Si2
A. Maldonado, H. Suderow, S. Vieira +2
CeRu2Si2 and CeRh2Si2 are two similar heavy fermion stoichiometric compounds located on the two sides of the magnetic quantum critical phase transition. CeRh2Si2 is an antiferromag…
Scanning microscopies of superconductors at very low temperatures
V. Crespo, A. Maldonado, J. A. Galvis +7
We discuss basics of scanning tunneling microscopy and spectroscopy (STM/S) of the superconducting state with normal and superconducting tips. We present a new method to measure th…
Tunneling spectroscopy of the superconducting state of URu2Si2
A. Maldonado, I. Guillamon, J. G. Rodrigo +4
We present measurements of the superconducting gap of URuSi made with scanning tunneling microscopy (STM) using a superconducting tip of Al. We find tunneling conductance c…
