Ladders in a magnetic field: a strong coupling approach

Mila, F. - In: The European Physical Journal B - Condensed Matter and … 6 (1998) 2, pp. 201-205

We show that non-frustrated and frustrated ladders in a magnetic field can be systematically mapped onto an XXZ Heisenberg model in a longitudinal magnetic field in the limit where the rung coupling is the dominant one. This mapping is valid in the critical region where the magnetization goes...
