Mixed-spin Heisenberg ladders in a magnetic field
D. S. Almeida, A. S. Bibiano, W. M. da Silva +1
In this work, we study alternating mixed-spin Heisenberg ladders in the magnetic field using density matrix renormalization group and linear spin-wave calculations. The…

Quantum bicritical point and phase separation in a frustrated Heisenberg ladder
D. S. Almeida, R. R. Montenegro-Filho
We use the density matrix renormalization group (DMRG) and a hard-core boson map to investigate the quantum phase transitions present in the phase diagram of the frustrated Heisenb…
