Comprehensive study of Fröhlich polaron
Once polaron model quantum monte carlo techniques polaron green's function strong coupling
2014/12/22
A study of the Fröhlich polaron model is performed on the basis of diagrammatic quantum Monte Carlo technique which is enhanced by novel method of spectral analysis of the polaron Green function....
Optical Conductivity of the Fröhlich Polaron
Light conductivity three-dimensional coupling mechanism function frequency light conductivity
2014/12/20
We present accurate results for optical conductivity of the three dimensional Fröhlich polaron in all coupling regimes. The systematic-error free diagrammatic quantum Monte Carlo method is employ...

Monte carlo feynman diagrams reforming particles breeding the particles
2014/12/20
We develop a Monte Carlo scheme for sampling series of Feynman diagrams for the proper self-energy, which are self-consistently expressed in terms of renormalized particle propagators. This approach i...
Fermi-polaron problem: Diagrammatic Monte Carlo method for divergent sign-alternating series
Diagram to monte carlo method Fermi gas particle condensed matter
2014/12/20
We use the diagrammatic Monte Carlo approach to solve the problem of a single spin-down fermion resonantly interacting with a Fermi gas of spin-up particles. Our solution is important for understandin...
Finding the ground state of a fermionic Hamiltonian using quantum Monte Carlo is a very difficult problem, due to the Fermi sign problem. While still scaling exponentially, full configuration-interact...
Perturbation theory of the mass enhancement for a polaron coupled to acoustic phonons
Perturbation theory of the mass enhancement acoustic phonons
2010/11/18
We use both a perturbative Green’s function analysis and standard perturbative quantum me-
chanics to calculate the decrease in energy and the effective mass for an electron interacting with acoustic...

Polaron Dynamics with Impurities in Conjugated Polymers
Polaron Dynamics Impurities Conjugated Polymers
2010/10/15
We study the charge transport by polarons in conjugated polymers in the presence of impurities. The effects on the polaron motion due to the symmetry of the chain is considered. The polaron dynamics i...
