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…
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…
High temperature transport in the one dimensional mass-imbalanced Fermi-Hubbard model
Thomas G. Kiely, Erich J. Mueller
We study transport in the one-dimensional mass-imbalanced Fermi-Hubbard model at infinite temperature, focusing on the case of strong interactions. Prior theoretical and experiment…
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…
Role of conservation laws in the Density Matrix Renormalization Group
Thomas G. Kiely, Erich J. Mueller
We explore matrix product state approximations to wavefunctions which have spontaneously broken symmetries or are critical. We are motivated by the fact that symmetries, and their…
Superfluidity in the 1D Bose-Hubbard Model
Thomas G. Kiely, Erich J. Mueller
We study superfluidity in the 1D Bose-Hubbard model using a variational matrix product state technique. We determine the superfluid density as a function of the Hubbard parameters…
Strong Increase in Ultrasound Attenuation Below T in SrRuO: Possible Evidence for Domains
Sayak Ghosh, Thomas G. Kiely, Arkady Shekhter +5
Recent experiments suggest that the superconducting order parameter of SrRuO has two components. A two-component order parameter has multiple degrees of freedom in the supe…
Anomalous Resistivity at Weak Coupling
Thomas G. Kiely, Erich J. Mueller
Recent cold atom experiments have observed bad and strange metal behaviors in strongly-interacting Fermi-Hubbard systems. Motivated by these results, we calculate the thermoelectri…
Transport in the 2D Fermi-Hubbard Model: Lessons from Weak Coupling
Thomas G. Kiely, Erich J. Mueller
We use quantum kinetic theory to calculate the thermoelectric transport properties of the 2D single band Fermi-Hubbard model in the weak coupling limit. For generic filling, we fin…
Relationship between the transverse-field Ising model and the XY model via the rotating-wave approximation
Thomas G. Kiely, J. K. Freericks
In a large transverse field, there is an energy cost associated with flipping spins along the axis of the field. This penalty can be employed to relate the transverse-field Ising m…
