Ladders in a magnetic field: a strong coupling approach

The European Physical Journal B: Condensed Matter and Complex Systems, 1998, vol. 6, issue 2, 201-205

Abstract: 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 from zero to saturation. It allows one to relate the properties of the critical phase (H c 1 , H c 2 , the critical exponents) to the exchange integrals and provide quantitative estimates of the frustration needed to create a plateau at half the saturation value for different models of frustration.
