Today many high performance computers are reachable over some network. However, the access and use of these computers is often complicated. This prevents many users to work on such machines. The Goal of the Remote Computation System (CS) is to provide easy access to modern parallel algorithms on supercomputers for the inexperienced user. RCS has an(More)
Elastic and inelastic neutron scattering experiments have been performed on the dimer spin system NH4CuCl3, which shows plateaus in the magnetization curve at m=1/4 and m=3/4 of the saturation value. Two structural phase transitions at T1 approximately 156 K and at T(2)=70 K lead to a doubling of the crystallographic unit cell along the b direction and as a(More)
