Electronic theory for scanning tunneling microscopy spectra in bilayer nickelate thin films
Marius Scholten, Steffen Bötzel, Frank Lechermann +2
Recent Scanning Tunneling Microscopy (STM) experiments measuring the superconducting gap features in thin films of superconducting bilayer nickelates La2PrNi2O7 at ambient pressure…
Theory of Josephson scanning microscopy with -wave tip on unconventional superconducting surface: application to BiSrCaCuO
Peayush Choubey, P. J. Hirschfeld
Josephson scanning tunneling microscopy (JSTM) is a powerful probe of the local superconducting order parameter, but studies have been largely limited to cases where superconductin…
Electronic Theory for Scanning Tunneling Microscopy Spectra in Infinite-Layer Nickelate Superconductors
Peayush Choubey, Ilya M. Eremin
Recent scanning tunneling microscopy (STM) observation of U-shaped and V-shaped spectra (and their mixture) in superconducting NdSrNiO thin films has been interpret…
Direct Visualization of a Static Incommensurate Antiferromagnetic Order by Suppressing the Superconducting Phase Coherence in Fe-doped Bi2Sr2CaCu2O8+delta
Siyuan Wan, Huazhou Li, Peayush Choubey +6
In cuprate superconductors, due to strong electronic correlations, there are multiple intertwined orders which either coexist or compete with superconductivity. Among them the anti…
Scattering Interference Signature of a Pair Density Wave State in the Cuprate Pseudogap Phase
Shuqiu Wang, Peayush Choubey, Yi Xue Chong +6
An unidentified quantum fluid designated as the pseudogap (PG) phase is produced by electron-density depletion in the CuO antiferromagnetic insulator. Current theories suggest…
Atomic-scale Electronic Structure of the Cuprate Pair Density Wave State Coexisting with Superconductivity
Peayush Choubey, Sang Hyun Joo, K. Fujita +9
The defining characteristic of hole-doped cuprates is -wave high temperature superconductivity. However, intense theoretical interest is now focused on whether a pair density wa…
Universality of scanning tunneling microscopy in cuprate superconductors
Peayush Choubey, Andreas Kreisel, T. Berlijn +2
We consider the problem of local tunneling into cuprate superconductors, combining model based calculations for the superconducting order parameter with wavefunction information ob…
Incommensurate charge ordered states in the model
Peayush Choubey, Wei-Lin Tu, Ting-Kuo Lee +1
We study the incommensurate charge ordered states in the model using the Gutzwiller mean field theory on large systems. In particular, we explore the prop…
Interpretation of scanning tunneling quasiparticle interference and impurity states in cuprates
A. Kreisel, Peayush Choubey, T. Berlijn +2
We apply a recently developed method combining first principles based Wannier functions with solutions to the Bogoliubov-de Gennes equations to the problem of interpreting STM data…
Visualization of atomic-scale phenomena in superconductors: application to FeSe
Peayush Choubey, T. Berlijn, A. Kreisel +2
We propose a simple method of calculating inhomogeneous, atomic-scale phenomena in superconductors which makes use of the wave function information traditionally discarded in the c…
