Robust series linearization of nonlinear advection-diffusion equations
T. Forrest Kieffer, Jakob Cupp, John S. Van Dyke +2
We consider nonlinear partial differential equations (PDEs) for advection-diffusion processes which are augmented by an auxiliary parameter such that corresponds to linea…
Mitigating Errors in DC Magnetometry via Zero-Noise Extrapolation
John S. Van Dyke, Zackary White, Gregory Quiroz
Zero-noise extrapolation (ZNE), a technique to estimate quantum circuit expectation values through noise scaling and extrapolation, is well-studied in the context of quantum comput…
Quantum tensor network algorithms for evaluation of spectral functions on quantum computers
Michael L. Wall, Aidan Reilly, John S. Van Dyke +2
We investigate quantum algorithms derived from tensor networks to simulate the static and dynamic properties of quantum many-body systems. Using a sequentially prepared quantum cir…
Time-crystalline behavior in central-spin models with Heisenberg interactions
Rafail Frantzeskakis, John Van Dyke, Leon Zaporski +5
Time-crystalline behavior has been predicted and observed in quantum central-spin systems with periodic driving and Ising interactions. Here, we theoretically show that it can also…
Scaling adaptive quantum simulation algorithms via operator pool tiling
John S. Van Dyke, Karunya Shirali, George S. Barron +3
Adaptive variational quantum simulation algorithms use information from the quantum computer to dynamically create optimal trial wavefunctions for a given problem Hamiltonian. A ke…
Preparing exact eigenstates of the open XXZ chain on a quantum computer
John S. Van Dyke, Edwin Barnes, Sophia E. Economou +1
The open spin-1/2 XXZ spin chain with diagonal boundary magnetic fields is the paradigmatic example of a quantum integrable model with open boundary conditions. We formulate a quan…
Preparing Bethe Ansatz Eigenstates on a Quantum Computer
John S. Van Dyke, George S. Barron, Nicholas J. Mayhall +2
Several quantum many-body models in one dimension possess exact solutions via the Bethe ansatz method, which has been highly successful for understanding their behavior. Neverthele…
Protecting Quantum Information in Quantum Dot Spin Chains by Driving Exchange Interactions Periodically
John S. Van Dyke, Yadav P. Kandel, Haifeng Qiao +3
Recent work has demonstrated a new route to discrete time crystal physics in quantum spin chains by periodically driving nearest-neighbor exchange interactions in gate-defined quan…
Floquet-Enhanced Spin Swaps
Haifeng Qiao, Yadav P. Kandel, John S. Van Dyke +5
The transfer of information between quantum systems is essential for quantum communication and computation. In quantum computers, high connectivity between qubits can improve the e…
Cubic hastatic order in the two-channel Kondo-Heisenberg model
Guanghua Zhang, John van Dyke, Rebecca Flint
Materials with non-Kramers doublet ground states naturally manifest the two-channel Kondo effect, as the valence fluctuations are from a non-Kramers doublet ground state to an exci…
Effects of Defects and Dephasing on Charge and Spin Currents in Two-Dimensional Topological Insulators
John S. Van Dyke, Dirk K. Morr
Using the non-equilibrium Keldysh Green's function formalism, we investigate the effect of defects on the electronic structure and transport properties of two-dimensional topologic…
Robust Upward Dispersion of the Neutron Spin Resonance in the Heavy Fermion Superconductor CeYbCoIn
Yu Song, John Van Dyke, I. K. Lum +10
The neutron spin resonance is a collective magnetic excitation that appears in copper oxide, iron pnictide, and heavy fermion unconventional superconductors. Although the resonance…

John S. Van Dyke, J. C. Seamus Davis, Dirk K. Morr
We demonstrate that the electronic bandstructure extracted from quasi-particle interference spectroscopy [Nat. Phys. 9, 468 (2013)] and the theoretically computed form of the super…
Controlling the Flow of Spin and Charge in Nanoscopic Topological Insulators
John S. Van Dyke, Dirk K. Morr
Controlling the flow of spin and charge currents in topological insulators (TIs) is a crucial requirement for applications in quantum computation and spin electronics. We demonstra…
Direct Evidence for a Magnetic f-electron Mediated Cooper Pairing Mechanism of Heavy Fermion Superconductivity in CeCoIn5

M. P. Allan, F. Massee, D. K. Morr +5
The Cooper pairing mechanism of heavy-fermion superconductors, while long hypothesized as due to spin fluctuations, has not been determined. It is the momentum space (k-space) stru…
