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…
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…
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…
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…
