Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
Quantum spin liquid phase in the Shastry-Sutherland model revealed by high-precision infinite projected entangled-pair states
Philippe Corboz, Yining Zhang, Boris Ponsioen +1
The Shastry-Sutherland model is an effective model of the layered material SrCu(BO), which exhibits an extremely rich phase diagram as a function of pressure and magnet…
Simulating Spin Dynamics of Supersolid States in a Quantum Ising Magnet
Yi Xu, Juraj Hasik, Boris Ponsioen +1
Motivated by a recent experimental study on the quantum Ising magnet that presented spectroscopic evidence of zero-field supersolidity (Chen e…
Improved summations of -point correlation functions of projected entangled-pair states
Boris Ponsioen, Juraj Hasik, Philippe Corboz
Numerical treatment of two dimensional strongly-correlated systems is both extremely challenging and of fundamental importance. Infinite projected entangled-pair states (PEPS), a c…
Superconducting stripes in the hole-doped three-band Hubbard model
Boris Ponsioen, Sangwoo S. Chung, Philippe Corboz
We study the ground state properties of the hole-doped three-band Hubbard (Emery) model, describing the copper-oxygen planes of the cuprates, using large-scale 2D tensor network ca…
Competing States in the Two-Dimensional Frustrated Kondo-Necklace Model
Matthias Peschke, Boris Ponsioen, Philippe Corboz
The interplay between Kondo screening, indirect magnetic interaction and geometrical frustration is studied in the two-dimensional Kondo-necklace model on the triangular lattice. U…
Variational methods for contracting projected entangled-pair states
Laurens Vanderstraeten, Lander Burgelman, Boris Ponsioen +5
The norms or expectation values of infinite projected entangled-pair states (PEPS) cannot be computed exactly, and approximation algorithms have to be applied. In the last years, m…
Automatic differentiation applied to excitations with Projected Entangled Pair States
Boris Ponsioen, Fakher F. Assaad, Philippe Corboz
The excitation ansatz for tensor networks is a powerful tool for simulating the low-lying quasiparticle excitations above ground states of strongly correlated quantum many-body sys…
Excitations with projected entangled pair states using the corner transfer matrix method
Boris Ponsioen, Philippe Corboz
We present an extension of a framework for simulating single quasiparticle or collective excitations on top of strongly correlated quantum many-body ground states using infinite pr…
Period 4 stripe in the extended two-dimensional Hubbard model
Boris Ponsioen, Sangwoo S. Chung, Philippe Corboz
We study the competition between stripe states with different periods and a uniform -wave superconducting state in the extended 2D Hubbard model at 1/8 hole doping using infinit…
