Quantum Spinon Oscillations
Zi Cai, Lei Wang, X. C. Xie +4
The full quantum dynamics of a spinon under external magnetic fields is investigated by using the time-evolving block decimation (TEBD) method within the microcanonical picture of…
Dynamical simulations of charged soliton transport in conjugated polymers with the inclusion of electron-electron interactions
Haibo Ma, Ulrich Schollwoeck
We present numerical studies of the transport dynamics of a charged soliton in conjugated polymers under the influence of an external time-dependent electric field. All relevant el…
The quasi-periodic Bose-Hubbard model and localization in one-dimensional cold atomic gases
G. Roux, T. Barthel, I. P. McCulloch +3
We compute the phase diagram of the one-dimensional Bose-Hubbard model with a quasi-periodic potential by means of the density-matrix renormalization group technique. This model de…
Systematic errors in Gaussian Quantum Monte Carlo and a systematic study of the symmetry projection method
P. Corboz, A. Kleine, F. F. Assaad +3
Gaussian Quantum Monte Carlo (GQMC) is a stochastic phase space method for fermions with positive weights. In the example of the Hubbard model close to half filling it fails to rep…
Methods for Time Dependence in DMRG
U. Schollwoeck, S. R. White
A major advance in density-matrix renormalization group (DMRG) calculations has been achieved by the invention of highly efficient DMRG techniques for the simulation of real-time d…
d-wave resonating valence bond states of fermionic atoms in optical lattices
Simon Trebst, Ulrich Schollwoeck, Matthias Troyer +1
We study controlled generation and measurement of superfluid d-wave resonating valence bond (RVB) states of fermionic atoms in 2D optical lattices. Starting from loading spatial an…
