  The newly discovered UTe2 superconductor is regarded as a heavy fermion
mixed-valence system with very peculiar properties within the normal and
superconducting states. It shows no signs of magnetic order but strong
anisotropy of a magnetic susceptibility and a superconducting critical field.
In addition to the heavy fermion-like behavior in the normal state, it exhibits
also a distinctive Schottky-type anomaly at about 12 K and a characteristic
excitations gap ~35-40 K. Here we show, by virtue of dynamical mean-field
theory calculations with a quasi-atomic treatment of electron correlations,
that ab-initio derived crystal-field splitting of the 5f2 ionic configuration
yields an agreement with these experimental observations. We analyze the
symmetry of magnetic and multipolar moment fluctuations that might lead to the
superconducting pairing at low temperatures. A close analogy of the normal
paramagnetic state of UTe2 to that of URu2Si2 in the Kondo arrest scenario is
revealed.
