Emergent Bound States and Impurity Pairs in Chemically Doped Shastry-Sutherland System
Zhenzhong Shi, William Steinhardt, David Graf +8
The search for novel unconventional superconductors is a central topic of modern condensed matter physics. Similar to other Mott insulators, Shastry-Sutherland (SSL) systems are pr…
Time Evolution of an Infinite Projected Entangled Pair State: an Efficient Algorithm
Piotr Czarnik, Jacek Dziarmaga, Philippe Corboz
An infinite projected entangled pair state (iPEPS) is a tensor network ansatz to represent a quantum state on an infinite 2D lattice whose accuracy is controlled by the bond dimens…
Thermodynamic properties of the Shastry-Sutherland model from quantum Monte Carlo simulations
Stefan Wessel, Ido Niesen, Jonas Stapmanns +4
We investigate the minus-sign problem that afflicts quantum Monte Carlo (QMC) simulations of frustrated quantum spin systems, focusing on spin S=1/2, two spatial dimensions, and th…
A ground state study of the spin-1 bilinear-biquadratic Heisenberg model on the triangular lattice using tensor networks
Ido Niesen, Philippe Corboz
Making use of infinite projected entangled pair states, we investigate the ground state phase diagram of the nearest-neighbor spin-1 bilinear-biquadratic Heisenberg model on the tr…
Thermal Critical Points and Quantum Critical End Point in the Frustrated Bilayer Heisenberg Antiferromagnet
Jonas Stapmanns, Philippe Corboz, Frederic Mila +3
We consider the finite-temperature phase diagram of the frustrated Heisenberg bilayer. Although this two-dimensional system may show magnetic order only at zero temperatu…
Finite correlation length scaling with infinite projected entangled-pair states
Philippe Corboz, Piotr Czarnik, Geert Kapteijns +1
We show how to accurately study 2D quantum critical phenomena using infinite projected entangled-pair states (iPEPS). We identify the presence of a finite correlation length in the…
