Quantum annealing for lattice models with competing long-range interactions
Jan Alexander Koziol, Kai Phillip Schmidt
We use superconducting qubit quantum annealing devices to determine the ground state of Ising models with algebraically decaying competing long-range interactions in the thermodyna…
Symmetry breaking and competing valence bond states in the star lattice Heisenberg antiferromagnet
Pratyay Ghosh, Jan Koziol, Samuel Nyckees +2
We investigate the ground state phase diagram of the spin- antiferromagnetic Heisenberg model on the star lattice using infinite projected entangled pair states (iPEPS) and hi…
Melting of devil's staircases in the long-range Dicke-Ising model
Jan Alexander Koziol, Anja Langheld, Kai Phillip Schmidt
We present quantum phase diagrams for the antiferromagnetic long-range Ising model with a linear coupling to a single bosonic mode on the square and triangular lattice. For zero co…
