Cooper quartets and fractional vortices in frustrated Josephson junction dice arrays
Erik Lennart Weerda, Olav F. Syljuåsen, Matteo Rizzi +1
Superconductivity mediated by Cooper quartets of charge 4e is a phenomenon of key importance for both the understanding of certain exotic superconductors and the engineering of qua…
Weak first-order phase transition out of the classical kagome spin liquid
Cecilie Glittum, Olav F. Syljuåsen
The low-temperature fate of the spin-liquid regime in the classical kagome Heisenberg antiferromagnet has been debated for over three decades. Using an expansion in the number of s…
Nematostriction in frustrated two-dimensional Heisenberg models
Olav F. Syljuåsen, Jens Paaske
We investigate the nematic phase transition in the Heisenberg --model on square and triangular lattices, accounting for finite lattice compressibility and bond-length-dep…
Field-induced Multi- States in a Pyrochlore Heisenberg Magnet
Cecilie Glittum, Olav F. Syljuåsen
We construct exact ground states of the - classical Heisenberg model on the pyrochlore lattice in the presence of a magnetic field. They are non-coplanar multi-$\vec{Q…
Widely existing mixed phase structure of quantum dimer model on square lattice
Zheng Yan, Zheng Zhou, Olav F. Syljuåsen +4
Since constraints hinder the application of numerical algorithms, phase diagrams of quantum dimer models are still controversial, even on the square lattice. The core controversy i…
Interplay between Magnetic and Vestigial Nematic Orders in the Layered - Classical Heisenberg Model
Olav F. Syljuåsen, Jens Paaske, Michael Schecter
We study the layered - classical Heisenberg model on the square lattice using a self-consistent bond theory. We derive the phase diagram for fixed as a function of…
