Extracting the Single-Particle Gap in Carbon Nanotubes with Lattice Quantum Monte Carlo
Evan Berkowitz, Christopher Koerber, Stefan Krieg +3
We show how lattice Quantum Monte Carlo simulations can be used to calculate electronic properties of carbon nanotubes in the presence of strong electron-electron correlations. We…
Hubbard-Stratonovich-like Transformations for Few-Body Interactions
Christopher Körber, Evan Berkowitz, Thomas Luu
Through the development of many-body methodology and algorithms, it has become possible to describe quantum systems composed of a large number of particles with great accuracy. Ess…
Sampling General N-Body Interactions with Auxiliary Fields
Christopher Körber, Evan Berkowitz, Thomas Luu
We present a general auxiliary field transformation which generates effective interactions containing all possible N-body contact terms. The strength of the induced terms can analy…
