The near-IR and X-ray flares in Sagittarius A* are believed to be produced by relativistic electrons via synchrotron and synchrotron self-Comptonization (SSC), respectively. These electrons are likely energized by turbulent plasma waves through second order Fermi acceleration that, in combination with the radiative cooling processes, produces a relativistic Maxwellian distribution in the steady...

The density of states (DOS) of electrons in two-dimensional (2D) quantum wells and the broadening of Landau levels (LL's) is evaluated. The electrons are assumed to interact with screened, charged impurities located at random in the material. The random location of the impurities leads to a disordered environment seen by the electrons. The screening of the impurities by the 2D electron gas is e...

This essay is a review of the topic of vortices in rapidly rotating BECs, where the system is in a quantum Hall-like regime and the density profile is of the Thomas-Fermi form. Also, in this paper, deviations from a triangular lattice is being considered while the system condensates into the lowest Landau levels.

We rely on a variational approach to derive a set of equations governing a trapped self-interacting Bose gas at finite temperature. In this work, we analyze the static situation both at zero and finite temperature in the Thomas-Fermi limit. We derive simple analytic expressions for the condensate properties at finite temperature. The noncondensate and anomalous density profiles are also analyze...

Sir Thomas Browne: Selected Writings, ed. by GEOFFREY KEYNES, London, Faber & Faber, 1968, pp. 416, illus., 50s. Sir Thomas Browne and Sir Geoffrey Keynes have this in common, that both were and are devoted to medicine and literature. However, Sir Geoffrey would seem to have the edge on Sir Thomas in that he is distinguished in both, whereas Sir Thomas's medical contributions were of no great i...

The equation of state (EOS) of finite nuclei is constructed in the relativistic Thomas-Fermi theory using the non-linear σ − ω − ρ model. The caloric curves are calculated by confining the nuclei in the freeze-out volume taken to be a sphere of size about 4 to 8 times the normal nuclear volume. The results obtained from the relativistic theory are not significantly different from those obtained...

Previous numerical studies on the ground state structure of Bose–Fermi mixtures mostly relied on Thomas–Fermi (TF) approximation for the Fermi gas. In this paper, we establish the existence and uniqueness of ground state solutions of Bose–Fermi mixtures at zero temperature for both a coupled Gross–Pitaevskii (GP) equations model and a model with TF approximation for fermions. To prove the uniqu...

E ects of merging histories of protoobjects on angular momentum distribution of present dark matter haloes are analysed. In a analysis of the angular momentum distributions by analytical methods (e.g., Heavens & Peacock 1989, Catelan & Theuns 1996), they have assumed that initially haloes are homogeneous ellipsoids and that the growth of the angular momentum halts at the maximum expansion time ...
