Dynamical correlation functions for the one-dimensional Bose-Hubbard insulator
Kevin zu Münster, Florian Gebhard, Satoshi Ejima +1
We calculate the dynamical current and kinetic-energy correlation functions for the first Mott lobe of the one-dimensional Bose-Hubbard model. We employ the strong-coupling expansi…
Generic Mott-Hubbard phase diagram for extended Hubbard models without Umklapp scattering
Florian Gebhard, Kevin Bauerbach, Örs Legeza
We determine the ground-state phase diagram for the 1/r-Hubbard model with repulsive nearest-neighbor interaction at half band-filling using the density-matrix renormalization grou…
A pedestrian approach to Einstein's formula with an application to photon dynamics
A. V. Nenashev, S. D. Baranovskii, F. Gebhard
There are several ways to derive Einstein's celebrated formula for the energy of a massive particle at rest, . Noether's theorem applied to the relativistic Lagrange functi…
Quantum states in disordered media. II. Spatial charge carrier distribution
A. V. Nenashev, S. D. Baranovskii, K. Meerholz +1
The space- and temperature-dependent electron distribution is essential for the theoretical description of the opto-electronic properties of disordered semiconduct…
Quantum states in disordered media. I. Low-pass filter approach
F. Gebhard, A. V. Nenashev, K. Meerholz +1
The current burst in research activities on disordered semiconductors calls for the development of appropriate theoretical tools that reveal the features of electron states in rand…
Accurate localization of Kosterlitz-Thouless-type quantum phase transitions for one-dimensional spinless fermions
Florian Gebhard, Kevin Bauerbach, Örs Legeza
We investigate the charge-density wave (CDW) transition for one-dimensional spinless fermions at half band-filling with nearest-neighbor electron transfer amplitude and interac…
