The effect of anisotropy for fluctuations of electric currents in magnetic field is addressed within framework of quantum measurements theory.It is shown that for free fermions in uniform magnetic field the anisotropy is of the same sign as one expects for chiral magnetic effect and is related to triangle anomaly.The corresponding decoherence functional contains anomalous off-diagonal terms leading to correlation of fluctuations between observables of opposite P-parity.

\nWe discuss the effect of anisotropy for fluctuations of electric currents in magnetic field using the quantum measurements theory language. Possible interpretation of parity-odd phenomena like Chiral Magnetic Effect in this framework is given. It is advocated that quantum-to-classical transition caused by decoherence plays crucial role. The talk is based on papers [1–3].\n
