Inhomogeneity, Fluctuations, and Gap Filling in Overdoped Cuprates
Miguel Antonio Sulangi, Willem Farmilo, Andreas Kreisel +3
Several recent experiments have challenged the premise that cuprate high-temperature superconductors approach conventional Landau-BCS behavior in the high-doping limit. We argue, b…
The Low-Temperature Phenomenology of Gap Inhomogeneity in the Cuprate Superconductors: High-Energy Granularity, Low-Energy Homogeneity, and Spectral Kinks
Miguel Antonio Sulangi
Scanning tunneling spectroscopy experiments on a number of cuprate superconductors have revealed that these materials are highly inhomogeneous. However, even though this inhomogene…
Self-supervised learning for denoising quasiparticle interference data
Ilse S. Kuijf, Willem O. Tromp, Tjerk Benschop +4
Tunneling spectroscopy is an important tool for the study of both real-space and momentum-space electronic structure of correlated electron systems. However, such measurements ofte…
Puddle formation, persistent gaps, and non-mean-field breakdown of superconductivity in overdoped (Pb,Bi)2Sr2CuO6+δ
Willem O. Tromp, Tjerk Benschop, Jian-Feng Ge +14
The cuprate high-temperature superconductors exhibit many unexplained electronic phases, but it was often thought that the superconductivity at sufficiently high doping is governed…
Correlations Among STM Observables in Disordered Unconventional Superconductors
Miguel Antonio Sulangi, W. A. Atkinson, P. J. Hirschfeld
New developments in scanning tunneling spectroscopy now allow for the spatially resolved measurement of the Josephson critical current between a tip and a superconducting sam…
Critical Currents in Conventional Josephson Junctions With Grain Boundaries
Miguel Antonio Sulangi, Laetitia Bettmann, T. A. Weingartner +5
It has been hypothesized that the variation of the critical currents in Nb/Al-AlO/Nb junctions is due to, among other effects, the presence of grain boundaries in the system. M…
Phase-sensitive determination of nodal -wave order parameter in single-band and multiband superconductors
Jakob Böker, Miguel Antonio Sulangi, Alireza Akbari +3
Determining the exact pairing symmetry of the superconducting order parameter in candidate unconventional superconductors remains an important challenge. Recently a new method, bas…
Multi-Atom Quasiparticle Scattering Interference for Superconductor Energy-Gap Symmetry Determination
Rahul Sharma, Andreas Kreisel, Miguel Antonio Sulangi +10
Complete theoretical understanding of the most complex superconductors requires a detailed knowledge of the symmetry of the superconducting energy-gap , for all mom…
Disorder and Critical Current Variability in Josephson Junctions
Miguel Antonio Sulangi, T. A. Weingartner, N. Pokhrel +3
We investigate theoretically the origins of observed variations in the critical currents of Nb/Al-AlO/Nb Josephson junctions in terms of various types of disorder. We consider…
Self-Energies and Quasiparticle Scattering Interference
Miguel Antonio Sulangi, Jan Zaanen
The cuprate high-temperature superconductors are known to host a wide array of effects due to interactions and disorder. In this work, we look at some of the consequences of these…
Quasiparticle Density of States, Localization, and Distributed Disorder in the Cuprate Superconductors
Miguel Antonio Sulangi, Jan Zaanen
We explore the effects of various kinds of random disorder on the quasiparticle density of states of two-dimensional d-wave superconductors using an exact real-space method, incorp…
Revisiting Quasiparticle Scattering Interference in High-Temperature Superconductors: The Problem of Narrow Peaks
Miguel Antonio Sulangi, Milan P. Allan, Jan Zaanen
We revisit the interpretation of quasiparticle scattering interference in cuprate high- superconductors. This phenomenon has been very successful in reconstructing the dispers…
The effect of the geometric potential and an external magnetic field on a charged particle on a helicoid
Miguel Antonio Sulangi, Quirino M. Sugon
We perform an analysis of the combined effects of geometry and a magnetic field for the case of a charged particle on a helicoid. The effective quantum potentials for a charged spi…
