The weak absorption spectrum of dideuterated water, D2O, has been recorded by Intracavity Laser Absorption Spectroscopy (ICLAS) between 11400 and 11900 cm . This spectrum is dominated by the 3m1 + m2 + m3 and the m1 + m2 + 3m3 centered at 11500.25 and 11816.64 cm , respectively. A total of 530 energy levels belonging to eight vibrational states were determined. The rovibrational assignment proc...

The chemical potentials of multicomponent fluids are derived in terms of the pair correlation functions for arbitrary number of components, interaction potentials, and dimensionality. The formally exact result is particularized to hard-sphere mixtures with zero or positive nonadditivity. As a simple application, the chemical potentials of three-dimensional additive hard-sphere mixtures are deri...

It is widely assumed that the observed universe is accelerating due to the existence of a new fluid component called dark energy. In this article, the thermodynamics consequences of a nonzero chemical potential on the dark energy component is discussed with special emphasis to the phantom fluid case. It is found that if the dark energy fluid is endowed with a negative chemical potential, the ph...

In this talk, we report the results discussed in [1], related to the phase structure of hot quark matter in presence of a background of chiral charge density, n5. The latter is introduced in the simplest way possible, namely by virtue of a chemical potential, μ5, conjugated to n5. In more detail, after a brief introduction and list of motivations of this kind of study, we discuss the interplay ...

Large-volume, high-temperature Bose-Einstein condensation is illustrated for a relativistic O(2)-invariant scalar field with fixed charge using the canonical ensemble. The standard, grand canonical results are reproduced for the infinite-volume limit. Finite-volume corrections are calculated and the results are found to differ from the grand canonical approximation in a consistent qualitative w...
