Destruction of Neel order and local spin spirals in insulating La_{2-x}Sr_xCuO_4
Andreas Luscher, Alexander I. Milstein, Oleg P. Sushkov
Starting from the t-J model, we derive an effective field theory describing the spin dynamics in the insulating phase of La_{2-x}Sr_xCuO_4, x < 0.055, at low temperature. Using Mon…

Spin-flop transitions and spin-wave gaps in La_2CuO_4
Andreas Luscher, Oleg P. Sushkov
We study the spin-wave spectrum and the spin-flop transitions in La_2CuO_4 in a uniform magnetic field at zero temperature. Using the non-linear sigma-model, we show that a field a…
