Maximally entangled states for higher local Hilbert space dimension — •Osterloh Andreas — Universität Duisburg-Essen, Duisburg, Germany.

The maximally entangled states for qubits are so called balanced states. There it means that as many 1's occur in the state as 0's. This concept is extended to arbitrary dimension of the local Hilbert space, or spin. Based on the simplest SL invariance, the determinant, a simple rule is extracted. This rule is hence transported into a set of equations, a state has to satisfy for being called "balanced". The "irreducibly balanced" states play a crucial role among these "maximally entangled" states, which are those states that are detected by some SL invariant.
