On the Localization of One-Photon States

Corin Adlard, E. R Pike, Sarben Sarkar

Single photon states with arbitrarily fast asymptotic power-law fall-off of energy density and photodetection rate are explicitly constructed. This goes beyond the recently discove…

Polaron effective mass from Monte Carlo simulations

P. E. Kornilovitch, E. R. Pike

A new Monte Carlo algorithm for calculating polaron effective mass is proposed. It is based on the path-integral representation of a partial partition function with fixed total qua…

Frequency-dependent spin susceptibility in the two-dimensional Hubbard model

C. E. Creffield, P. E. Kornilovitch, E. G. Klepfish +2

A Quantum Monte Carlo calculation of dynamical spin susceptibility in the half-filled 2D Hubbard model is presented for temperature and an intermediate on-site repulsion $…

Singularity of the density of states in the two-dimensional Hubbard model from finite size scaling of Yang-Lee zeros

E. Abraham, I. M. Barbour, P. H. Cullen +3

A finite size scaling is applied to the Yang-Lee zeros of the grand canonical partition function for the 2-D Hubbard model in the complex chemical potential plane. The logarithmic…

Spectral weight function for the half-filled Hubbard model: a singular value decomposition approach

C. E. Creffield, E. G. Klepfish, E. R. Pike +1

The singular value decomposition technique is used to reconstruct the electronic spectral weight function for a half-filled Hubbard model with on-site repulsion from Quantum…
