Spectral functions of the spinless Holstein model
J. Loos, M. Hohenadler, H. Fehske
An analytical approach to the one-dimensional spinless Holstein model is proposed, which is valid at finite charge-carrier concentrations. Spectral functions of charge carriers are…
Crystallization in two-component Coulomb systems
M. Bonitz, V. S. Filinov, V. E. Fortov +2
The analysis of Coulomb crystallization is extended from one-component to two-component plasmas. Critical parameters for the existence of Coulomb crystals are derived for both clas…
Minimal Cuntz-Krieger Dilations and Representations of Cuntz-Krieger Algebras
B. V. Rajarama Bhat, Santanu Dey, Joachim Zacharias
Given a contractive tuple of Hilbert space operators satisfying certain -relations we show that there exists a unique minimal dilation to generators of Cuntz-Krieger algebras or…
Many-polaron problem by cluster perturbation theory
Martin Hohenadler, Gerhard Wellein, Andreas Alvermann +1
The carrier-density dependence of the photoemission spectrum of the Holstein many-polaron model is studied using cluster perturbation theory combined with an improved cluster diago…
Optical absorption and activated transport in polaronic systems
G. Schubert, G. Wellein, A. Weiße +2
We present exact results for the optical response in the one-dimensional Holstein model. In particular, by means of a refined kernel polynomial method, we calculate the ac and dc e…
The Kernel Polynomial Method
Alexander Weisse, Gerhard Wellein, Andreas Alvermann +1
Efficient and stable algorithms for the calculation of spectral quantities and correlation functions are some of the key tools in computational condensed matter physics. In this ar…
