Fermi Liquid Behavior

The electrical resistivity of single crystalline HoNi 2 B 2 C has been measured at high pressure and magnetic fields. The three anomalies in the magnetoresistance due to metamagnetic transitions are observed both at ambient and high pressures. It is found that the metamagnetic transition fields increase with increasing pressure. The temperature dependence of electrical resistivity is strongly dependent on magnetic field. Non Fermi liquid behavior is observed near the metamagnetic transition fields. But the normal Fermi liquid behavior recovers after completing the phase transition. The Grüneisen parameters are also calculated to examine the stability of electronic state.

AbstractThe hyperchaos and multistability of electron acoustic waves in a quantum plasma model comprising of nondegenerate cold and degenerate hot electrons and stationary ions are investigated. A six-dimensional dynamical system is constructed from the fluid equations of the model considering traveling wave transformation. The stability analysis of the system is done by finding out the equilibria in the inertia frame. It is interesting to investigate that though the novel system is conservative, it can produce hyperchaos for a set of associated parameters. We have also reported the coexistence of many hyperchaotic attractors as the system is extremely sensitive to the initials. The signature of hyperchaos and coexisting hyperchaos in a conservative quantum plasma system has never been reported before.

Lineaments play an important role in the stability of structures such as slopes, foundations, dams and buildings. Identification of the presence of lineament is important especially at planning and construction stage to enable mitigation measures/controls can selected earlier. The combined techniques of satellite image downloaded from Google Earth interpretation and electrical resistivity survey can assist in the identification and verification process of lineament structures. In this study, interpretation of lineament was done using satellite images Google Earth in the laboratory. Orientation and position of every lineament was determined accurately in the field. Electrical resistivity survey was conducted using Wanner configuration that cross the lineament in the field. The electrical resistivity results showed the presence of lineament structural in the pseudo section and prove the effectiveness of combination of both techniques to detect and confirm the presence of structural lineament.

The Stability

The stability of a gravitating, homogeneous, incompressible fluid layer of infinite extent but finite thickness is considered, including Hall effect, by the use of the normal mode method. A uniform magnetic field is assumed to be present throughout parallel to its boundary. The displacement current is neglected. An asymptotic analysis for small nonzero Hall current shows a destabilizing effect of order ε where ε is the perturbation parameter. The stability analysis is restricted to plane-symmetric modes.

The Stability

Boundary conditions appropriate to a model with finite ion mass corrections of ideal hydromagnetic theory are reviewed. It is shown that these boundary conditions have been correctly satisfied in earlier theory for the stability of an interface between two semi-infinite regions. This theory predicts instability due to Hall current.

The Stability

The stability of a non-conducting, compressible fluid (gas) flowing across the surface of incompressible conducting fluid (liquid) is discussed. Finite resistivity and Hall current are included in the hydromagnetic equations, together with surface tension. Both subsonic and supersonic flows are treated and some new instabilities are found, together with modifications to real and oscillatory modes obtained in earlier treatments.

The strongly correlated metals U 2 Pt 2 In and U 3 Ni 3 Sn 4 show pronounced non-Fermi liquid (NFL) phenomena at ambient pressure. Here we review single-crystal electrical resistivity measurements under pressure (p ≤ 1.8 GPa) conducted to investigate the stability of the NFL phase. For tetragonal U 2 Pt 2 In (I ‖ a) we observe a rapid recovery of the Fermi-liquid T2-term with pressure. The Fermi-liquid temperature varies as T FL ~ p-p c , where p c =0 is a critical pressure. The analysis within the magnetotransport theory of Rosch provides evidence for the location of U 2 Pt 2 In at a p=0 antiferromagnetic critical point (QCP). In the case of cubic U 3 Ni 3 Sn 4 we find T FL ~ (p-p c )1/2. The analysis provides evidence for an antiferromagnetic QCP in U 3 Ni 3 Sn 4 at a negative pressure p c = -0.04±0.04 GPa
