Renormalized Perturbation Theory for Fast Evaluation of Feynman Diagrams on the Real Frequency Axis
M. D. Burke, Maxence Grandadam, J. P. F. LeBlanc
We present a method to accelerate the numerical evaluation of spatial integrals of Feynman diagrams when expressed on the real frequency axis. This can be realized through use of a…
Influence of incommensurate structure on the elastic constants of crystalline BiSrCaCuO by Brillouin light scattering spectroscopy
B. D. E. McNiven, J. P. F. LeBlanc, G. T. Andrews
Brillouin light scattering spectroscopy was used to probe the room-temperature elasticity of crystalline high- superconductor BiSrCaCuO. A complete set of…
Dynamic Response of an Electron Gas: Towards the Exact Exchange-Correlation Kernel
James P. F. LeBlanc, Kun Chen, Kristjan Haule +2
Precise calculations of dynamics in the homogeneous electron gas (jellium model) are of fundamental importance for design and characterization of new materials. We introduce a diag…
One- and two-particle properties of the weakly interacting two-dimensional Hubbard model in proximity to the van Hove singularity
B. D. E. McNiven, Hanna Terletska, G. T. Andrews +1
We study the weak-coupling limit of the Hubbard model on a two-dimensional square lattice using a direct perturbative approach. Aided by symbolic computational tools…
Long-wavelength phonon dynamics in incommensurate Bi2Sr2CaCu2O(8+delta) crystals by Brillouin light scattering spectroscopy
Bradley D. E. McNiven, James P. F. LeBlanc, Gordon T. Andrews
Room temperature phonon dynamics in crystals of the high-Tc superconductor Bi2Sr2CaCu2O(8+delta) were probed using Brillouin light scattering spectroscopy. Eight distinct acoustic…
LIBAMI: Implementation of Algorithmic Matsubara Integration
Hossam Elazab, B. D. E. McNiven, J. P. F. LeBlanc
We present libami, a lightweight implementation of algorithmic Matsubara integration (AMI) written in C++. AMI is a tool for analytically resolving the sequence of nested Matsubara…
