Quantum Annealing Approaches to the Phase-Unwrapping Problem in Synthetic-Aperture Radar Imaging
Khaled A. Helal Kelany, Nikitas Dimopoulos, Clemens P. J. Adolphs +2
The focus of this work is to explore the use of quantum annealing solvers for the problem of phase unwrapping of synthetic aperture radar (SAR) images. Although solutions to this p…
The magnon-mediated attraction between two holes doped in a CuO layer
Mirko M. Moeller, Clemens P. J. Adolphs, Mona Berciu
Using a realistic multi-band model for two holes doped into a CuO layer, we devise a method to turn off the magnon-mediated interaction between the holes. This allows us to ver…
Multi-Community Detection in Signed Graphs Using Quantum Hardware
Ehsan Zahedinejad, Daniel Crawford, Clemens Adolphs +1
Signed graphs serve as a primary tool for modelling social networks. They can represent relationships between individuals (i.e., nodes) with the use of signed edges. Finding commun…
Phonon-mediated repulsion, sharp transitions and (quasi)self-trapping in the extended Peierls-Hubbard model
J. Sous, M. Chakraborty, C. P. J. Adolphs +2
We study two identical fermions, or two hard-core bosons, in an infinite chain and coupled to phonons by interactions that modulate their hopping as described by the Peierls/Su-Sch…
Non-Zhang-Rice singlet character of the first ionization state of T-CuO
Clemens P J Adolphs, Simon Moser, George A Sawatzky +1
We argue that tetragonal CuO (T-CuO) has the potential to finally settle long-standing modelling issues for cuprate physics. We compare the one-hole quasiparticle (qp) dispersion o…
Strongly bound yet light bipolarons for double-well electron-phonon coupling
Clemens PJ Adolphs, Mona Berciu
We use the Momentum Average approximation (MA) to study the ground-state properties of strongly bound bipolarons in the double-well electron-phonon (el-ph) coupling model, which de…
