Classical phase spaces have been widely applied in physics, engineering, economics or biology. In this thesis, phase spaces of quantum systems are considered, which have become a powerful tool for describing, analyzing, and tomographically reconstruc

In this thesis the elementary excitations of the spin-1=2 Heisenberg antiferromagnet on the square lattice are studied. This fundamental model is a paradigmatic example for long range ordered quantum phases and the spontaneous breaking of a continuou

In this thesis we used ESR to investigate magnetic properties of low D vandium and copper oxides in which small quantum spins are arranged in 1D chains and 2D layers. The thesis covers five different low dimensional spin systems. They turned out to b
