Checkerboard Bose Hubbard Ladders using Transmon Arrays
Pranjal Praneel, Thomas G Kiely, Andre G Petukhov +1
Adding a sublattice bias to the two dimensional Bose Hubbard model greatly enriches the available physics, and introduces knobs which can be used to control and interrogate the qua…
Exact kinetic propagators for coherent state complex Langevin simulations
Thomas G. Kiely, Ethan C. McGarrigle, Glenn H. Fredrickson
We introduce and benchmark an improved algorithm for complex Langevin simulations of bosonic coherent state path integrals. Our approach utilizes a Strang splitting of the imaginar…
Vacancy-assisted superfluid drag
Thomas G. Kiely, Chao Zhang, Erich J. Mueller
We study superfluid drag in the two-component Bose-Hubbard model with infinitely strong repulsive interactions. In this system, all transport is mediated by the motion of empty sit…
Continuous Wigner-Mott transition at
Thomas G. Kiely, Debanjan Chowdhury
Electrons can organize themselves into charge-ordered states to minimize the effects of long-ranged Coulomb interactions. In the presence of a lattice, commensurability constraints…
Multi-site gates for state preparation in quantum simulation of the Bose Hubbard Model
Pranjal Praneel, Thomas G. Kiely, Erich J. Mueller +1
We construct a sequence of multi-site gates which transform an easily constructed product state into an approximation to the superfluid ground state of the Bose-Hubbard model. The…
