Density matrix renormalization group study of optical conductivity in the one-dimensional Mott insulator Sr_2CuO_3
Shigetoshi Sota, Takami Tohyama
Applying newly developed dynamical density matrix renormalization group techniques at zero and finite temperatures to a Hubbard-Holstein model at half-filling, we examine the optic…
Relaxation Dynamics of Photocarriers in One-Dimensional Mott Insulators Coupled to Phonons
Hiroaki Matsueda, Shigetoshi Sota, Takami Tohyama +1
We examine recombination processes of photocarriers in one-dimensional Mott insulators coupled to phonons. Performing density matrix renormalization group calculations, we find tha…
Chirality in spin-1/2 zigzag XY chain: Low-temperature density-matrix renormalization group study
Takanori Sugimoto, Shigetoshi Sota, Takami Tohyama
We study spin chirality for a spin-1/2 zigzag XY chain at low temperature by applying a low-temperature density-matrix renormalization group technique. We calculate temperature dep…
