Entropy and specific heat of the infinite-dimensional three-orbital Hubbard model

Yue, Changming ; Werner, Philipp

In: Physical Review B, 2020, vol. 102, no. 8, p. 085102

The Hund's coupling in multiorbital Hubbard systems induces spin freezing and associated Hund metal behavior. Using dynamical mean-field theory, we explore the effect of local moment formation, spin, and charge excitations on the entropy and specific heat of the three-orbital model. For fillings 2≲n<3 and low temperature, we demonstrate a substantial enhancement of the entropy in the...

Synoptic conditions and atmospheric moisture pathways associated with virga and precipitation over coastal Adélie Land in Antarctica

Jullien, Nicolas ; Vignon, Étienne ; Sprenger, Michael ; Aemisegger, Franziska ; Berne, Alexis

In: The Cryosphere, 2020, vol. 14, no. 5, p. 1685–1702

Precipitation falling over the coastal regions of Antarctica often experiences low-level sublimation within the dry katabatic layer. The amount of water that reaches the ground surface is thereby considerably reduced. This paper investigates the synoptic conditions and the atmospheric transport pathways of moisture that lead to either virga – when precipitation is completely sublimated –...
