Spin-dependent interaction in the deconfined phase of QCD
  Spin-dependent deconfined interaction in the Q\barQ system is derived from the field correlators known from lattice and analytic calculations. As a result hyperfine splitting is found numerically for charmonium, bottomonium and strangeonium in the range T_c<T<2T_c. Spin-orbit interaction due to magnetic correlators (the Thomas term) is able to produce numerous Q\barQ bound states with accumulation point at M=m_Q+m_\barQ. Possible influence of these effects on the thermodynamics of quark-gluon plasma is discussed.
