Abstract
We have found spatial decoherence (loss of phase coherence between dis tant points in space) of quantum states and chaotic behavior (''turbul ence'') of quantum-mechanical currents for a nonlinear oscillator in a magnetic field. Use of quantum currents is dictated by the fact that they are simultaneously phase-sensitive and gauge-invariant measures. The theory is applicable to an electron in a quantum dot with soft con fining potential in a magnetic field. [S0031-9007(98)07722-9].
