Spin polaron in the J1-J2 Heisenberg model
I. J. Hamad, A. E. Trumper, A. E. Feiguin +1
We have studied the validity of the spin polaron picture in the frustrated J1-J2 Heisenberg model. For this purpose, we have computed the hole spectral functions for the Neel, coll…
Density Matrix Renormalization Group Study of Incompressible Fractional Quantum Hall States
A. E. Feiguin, E. Rezayi, C. Nayak +1
We develop the Density Matrix Renormalization Group (DMRG) technique for numerically studying incompressible fractional quantum Hall (FQH) states on the sphere. We calculate accura…
Pairing states of a polarized Fermi gas trapped in a one-dimensional optical lattice
A. E. Feiguin, F. Heidrich-Meisner
We study the properties of a one-dimensional (1D) gas of fermions trapped in a lattice by means of the density matrix renormalization group method, focusing on the case of unequal…
Transport through quantum dots: A combined DMRG and cluster-embedding study
F. Heidrich-Meisner, G. B. Martins, C. A. Busser +5
The numerical analysis of strongly interacting nanostructures requires powerful techniques. Recently developed methods, such as the time-dependent density matrix renormalization gr…
