Nonresonant inelastic light scattering in the Hubbard model

Inelastic light scattering from electrons is a symmetry-selective probe of the charge dynamics within correlated materials. Many measurements have been made on correlated insulators, and recent exact solutions in large dimensions explain a number of anomalous features found in experiments. Here we focus on the correlated metal, as described by the Hubbard model away from half filling. We can determine the B1g Raman response and the inelastic X-ray scattering along the Brillouin zone diagonal exactly in the large dimensional limit. We find a number of interesting features in the light scattering response which should be able to be seen in correlated metals such as the heavy fermions.Comment: 9 pages, 7 figures, typeset with ReVTe

Mass-Induced Crystalline Color Superconductivity

We demonstrate that crystalline color superconductivity may arise as a result of pairing between massless quarks and quarks with nonzero mass m_s. Previous analyses of this phase of cold dense quark matter have all utilized a chemical potential difference \delta\mu to favor crystalline color superconductivity over ordinary BCS pairing. In any context in which crystalline color superconductivity occurs in nature, however, it will be m_s-induced. The effect of m_s is qualitatively different from that of \delta\mu in one crucial respect: m_s depresses the value of the BCS gap \Delta_0 whereas \delta\mu leaves \Delta_0 unchanged. This effect in the BCS phase must be taken into account before m_s-induced and \delta\mu-induced crystalline color superconductivity can sensibly be compared.Comment: 12 pages, 4 figures. v2: very small change onl

Exploring unusual metastasis in carcinoma breast: Divulging vulval metastasis

Regional lymph nodes, bones, brain, lung, and liver are the most common sites of the breast carcinoma metastases. Nodular or ulcerated lesions over the vulva are ignored for a long time as benign lesions by the patient and there is a lot of hesitance to undergo the examination. Here, we report the case of a 41-year-old female with an isolated, asymptomatic vulval metastasis of Invasive ductal carcinoma of the breast. The purpose of reporting this case is to make the clinicians aware of this rare site of metastasis of breast cancer and the importance of pelvic examination in follow-up patients

UHECR Acceleration in Dark Matter Filaments of Cosmological Structure Formation

A mechanism for proton acceleration to ~10^21eV is suggested. It may operate in accretion flows onto thin dark matter filaments of cosmic structure formation. The flow compresses the ambient magnetic field to strongly increase and align it with the filament. Particles begin the acceleration by the ExB drift with the accretion flow. The energy gain in the drift regime is limited by the conservation of the adiabatic invariant p_perp^2/B. Upon approaching the filament, the drift turns into the gyro-motion around the filament so that the particle moves parallel to the azimuthal electric field. In this 'betatron' regime the acceleration speeds up to rapidly reach the electrodynamic limit $cp_{max}=eBR$ for an accelerator with magnetic field $B$ and the orbit radius $R$ (Larmor radius). The periodic orbit becomes unstable and the particle slings out of the filament to the region of a weak (uncompressed) magnetic field, which terminates the acceleration. The mechanism requires pre-acceleration that is likely to occur in structure formation shocks upstream or nearby the filament accretion flow. Previous studies identify such shocks as efficient proton accelerators to a firm upper limit ~10^19.5 eV placed by the catastrophic photo-pion losses. The present mechanism combines explosive energy gain in its final (betatron) phase with prompt particle release from the region of strong magnetic field. It is this combination that allows protons to overcome both the photo-pion and the synchrotron-Compton losses and therefore attain energy 10^21 eV. A requirement on accelerator to reach a given E_max placed by the accelerator energy dissipation \propto E_{max}^{2}/Z_0 due to the finite vacuum impedance Z_0 is circumvented by the cyclic operation of the accelerator.Comment: 34 pages, 10 figures, to be published in JCA

The Crystallography of Color Superconductivity

We develop the Ginzburg-Landau approach to comparing different possible crystal structures for the crystalline color superconducting phase of QCD, the QCD incarnation of the Larkin-Ovchinnikov-Fulde-Ferrell phase. In this phase, quarks of different flavor with differing Fermi momenta form Cooper pairs with nonzero total momentum, yielding a condensate that varies in space like a sum of plane waves. We work at zero temperature, as is relevant for compact star physics. The Ginzburg-Landau approach predicts a strong first-order phase transition (as a function of the chemical potential difference between quarks) and for this reason is not under quantitative control. Nevertheless, by organizing the comparison between different possible arrangements of plane waves (i.e. different crystal structures) it provides considerable qualitative insight into what makes a crystal structure favorable. Together, the qualitative insights and the quantitative, but not controlled, calculations make a compelling case that the favored pairing pattern yields a condensate which is a sum of eight plane waves forming a face-centered cubic structure. They also predict that the phase is quite robust, with gaps comparable in magnitude to the BCS gap that would form if the Fermi momenta were degenerate. These predictions may be tested in ultracold gases made of fermionic atoms. In a QCD context, our results lay the foundation for a calculation of vortex pinning in a crystalline color superconductor, and thus for the analysis of pulsar glitches that may originate within the core of a compact star.Comment: 41 pages, 13 figures, 1 tabl

Sorption Characteristics of Binary Hydrocarbon Mixtures in Low Density Polyethylene

Sorptions of six pure hydrocarbons and five of their binary mixtures in low density polyethylene have been measured. Composition of the binary mixture sorbed has been determined experimentally by a direct method. Selectivity uue to sorption has been shown to constitute a major portion of the permselectivity. Correlations have been developed to predict the quantity and composition of the binary mixture sorbed in the polymer at any temperature, when the pure compound sorptions at some temperature are known

Lipoprotein lipase gene HindIII polymorphism and risk of myocardial infarction in South Indian population

Introduction: Studies have reported an association between lipoprotein lipase (LPL) gene and myocardial infarction in some populations. Therefore, the present study aimed to investigate the association of the HindIII polymorphism of the (LPL) gene with myocardial infarction and to explore its potential role in susceptibility in a South Indian population. Subjects and methods: We included a total of 412 subjects (202 myocardial infarction patients and 210 age- and sex-matched controls). Demographic and clinical characteristics were collected. Lipid profiles were estimated. DNA was isolated and the LPL gene HindIII polymorphism was determined by polymerase chain reaction. Results: Comparison of the lipid profiles between patients and controls showed that patients had statistically high significant values (p = 0.0001). The H+ H+ genotype of the LPL gene is associated with myocardial infarction. H+ H+ vs. H− H− was χ2 = 19.4, OR 3.1, CI 95% 1.8–5.2, p < 0.0001. Conclusion: Our study strongly suggests that the LPL gene HindIII Hþ Hþ genotype is an independent risk factor for first MI

Studies on the Effect of Microbial Inoculants on Growth and Yield of Capsicum (Capsicum annuum L.)

Capsicum is a genus of flowering plants in the nightshade family Solanaceae. Capsicum is rich in beta carotene, capsaicin, vitamin A, C and antioxidant properties. Microbial inoculants are used to improve plant nutrition and also promote plant growth by stimulating plant hormone production. In order to increase growth and yield of capsicum, an experiment was conducted under greenhouse by using different combination of microbial inoculants [Azotobacter chroococcum (AC) as nitrogen fixers, Bacillus megaterium (BM) as Phosphate solubilizer, Glomus fasciculatum (GF) as phosphate mobilizer] at different level of nitrogen, phosphorus and potassium (50%, 75%, 100%) along with recommended dose of farm yard manure and vermicompost. Different growth parameters and yield parameters were significantly superior in the plants treated with combination of AC + BM + 75% nitrogen and phosphorus + 100% potassium + vermicompost. This was followed by treatment combination (AC + BM + GF + 75% nitrogen and phosphorus + 100% potassium + Farm yard manure) and least growth and yield was observed in the plants treated with the combination of 75% nitrogen and phosphorus + 100% potassium. The results indicated that the combined effect of microbial inoculants and inorganic fertilizer have best effect on growth and yield of capsicum
