The Specific Heat of Normal, Degenerate Quark Matter: Non-fermi Liquid Corrections
In normal degenerate quark matter, the exchange of dynamically screened transverse gluons introduces infrared divergences in the quark self-energies that lead to the breakdown of the Fermi liquid description. If the core of neutron stars are composed of quark matter with a normal component, cooling by direct quark Urca processes may be modified by non-Fermi liquid corrections. We find that whil...
متن کاملNeutrino Emissivity of Degenerate Quark Matter
An exact numerical calculation of neutrino emissivity of two and three flavour quark matter have been carried out. We find that the neutrino emissivity obtained from the Iwamoto formula is in qualitative agreement with our calculation for two flavour quark matter. For three flavour case, on the other hand we find that the Iwamoto formula overestimates the numerical values by ∼2 orders of magnit...
متن کاملNon-Fermi Liquid Effective Field Theory of Dense QCD Matter
where vμ = (1, ~v). The field ψv describes particles and holes with momenta p = μ(0, ~v)+k, where k ≪ μ. We will write k = k0 + k‖ + k⊥ with ~k‖ = ~v(~k · ~v) and ~k⊥ = ~k − ~k‖. L4f denotes four-fermion operators in the BCS and zero sound channel. At energies below the screening scale gμ hard dense loops have to be resummed. The generating functional for hard dense loops in gluon n-point funct...
متن کاملNonanalytic corrections to the Fermi-liquid behavior
The issue of nonanalytic corrections to the Fermi-liquid behavior is revisited. Previous studies have indicated that the corrections to the Fermi-liquid forms of the specific heat and the static spin susceptibility (C}T , xs 5const) are nonanalytic in D<3 and scale as dC(T)}T, xs(T)}T , and xs(Q)}Q , with extra logarithms in D53 and 1. It is shown that these nonanalytic corrections originate fr...
متن کاملCrossover between Fermi liquid and non-Fermi liquid behavior in the non-centrosymmetric compound Yb2Ni12P7.
A crossover from a non-Fermi liquid to a Fermi liquid phase in Yb2Ni12P7 is observed by analyzing electrical resistivity ρ(T), magnetic susceptibility χ(T), specific heat C(T), and thermoelectric power S(T) measurements. The electronic contribution to specific heat, Ce(T), behaves as Ce(T)/T∼-ln(T) for 5 K<T<15 K, which is consistent with non-Fermi liquid behavior. Below T∼4 K, the upturn in Ce...
