Preparation for Quantum Simulation of the 1+1D O(3) Non-linear σ-Model using Cold Atoms
Anthony N. Ciavarella, Stephan Caspar, Hersh Singh +1
The 1+1D O(3) non-linear σ-model is a model system for future quantum lattice simulations of other asymptotically-free theories, such as non-Abelian gauge theories. We find that ut…
State Preparation in the Heisenberg Model through Adiabatic Spiraling
Anthony N. Ciavarella, Stephan Caspar, Marc Illa +1
An adiabatic state preparation technique, called the adiabatic spiral, is proposed for the Heisenberg model. This technique is suitable for implementation on a number of quantum si…
Simulating Heisenberg Interactions in the Ising Model with Strong Drive Fields
Anthony N. Ciavarella, Stephan Caspar, Hersh Singh +2
The time-evolution of an Ising model with large driving fields over discrete time intervals is shown to be reproduced by an effective XXZ-Heisenberg model at leading order in the i…
From asymptotic freedom to vacua: Qubit embeddings of the O(3) nonlinear model
Stephan Caspar, Hersh Singh
Conventional lattice formulations of vacua in the -dimensional nonlinear sigma model suffer from a sign problem. Here, we construct the first sign-problem-fr…
