Theory of the Tetragonal-to-Orthorhombic Structural Phase Transition in La2CuO4. (1998)

Sahu, D., George, Thomas F.

A phenomenological free energy for the tetragonal-to-orthorhombic structural phase transition in La CuO is derived from symmetry principles. The critical properties of the model free energy are...

Coupled Even-Parity Superconducting States: Square Lattice. (1998)

Langner, A., Sahu, D., George, Thomas F.

The Ginzburg-Landau free energy density for the coupling of s-wave and d-wave superconducting states in square planar symmetry is considered. Four single-order parameter states and a mixed state are...

Analysis of Thermodynamic and Transport Properties of La(2-x)M(x) CuO4 and YBa2CuO(7 - delta) Superconductors, (1998)

Langner, A., Sahu, D., George, Thomas F.

Anisotropic Ginzburg-landau theory for coupled s-wave and d-wave order parameters is used to analyze the unique thermodynamic and transport properties of the new La2-x(Ba,Sr)xCu04 and YBa2Cu307-delta...

Coupled s-Wave and d-Wave States in the Heavy Fermion Superconductor U sub 1-x Th sub x Be sub 13. (1998)

Langner, A., Sahu, D., George, Thomas F.

In the heavy fermion superconductor U(1-x)Th(x)Be13, superconducting states coexist for thorium concentrations O < or = 0.06. Assuming s-wave and d-wave symmetries for these states, a Ginzburg-Landau...

Overview of High-Temperature Superconductivity: Theory, Surfaces, Interfaces and Bulk Systems. (1998)

Sahu, D., Langner, A., George, Thomas F., Weaver, J. H.

An overview of the theoretical and experimental aspects of the recently discovered superconducting compounds is presented. This overview is divided into three sections. In the first section a review...

Density of States in a Resonant Tunneling Structure. (1998)

Trzeciakowski, W., Sahu, D., George, Thomas F.

The change in the density of states Delta (E) brought about by the double-barrier structure is calculated. The positions and widths narrow resonances coincide with those obtained from transmission...

Dwell Time and Average Local Speed in a Resonant Tunneling Structure. (1998)

Pandey, L. N., Sahu, D., George, Thomas F.

The dwell times and the average local speeds of an electron in a resonant tunneling structure depend sensitively on the matching parameter at the interfaces. There is a need to carry out microscopic...

Density of Electronic States in a Biased Resonant Tunneling Structure. (1998)

Pandey, L. N., Sahu, D., George, Thomas F.

We calculate the change in the density of states due to a biased resonant tunneling structure. The maximum of the density of states near resonance gets shifted towards the low-energy side compared to...

Reply to 'Coupled s- and d-Wave States in the Thorium-Doped Heavy-Fermion Superconductor UBe13' by H. Pleiner and H. R. Brand. (1998)

Sahu, D., Langner, A., George, Thomas F.

We discuss the points raised by H. Pleiner and H. R. Brand concerning our earlier work on Ube(13) and thorium-doped UBe(13). Keywords: Superconductor 13; Thorium doped; Heavy fermion; Coupled s- and...

Specific Heat of Anisotropic Superconductors. (1998)

Sahu, D., Langner, A., George, Thomas F.

A theoretical approach for obtaining a Ginzburg-Landau free-energy expansion for a class of even-parity superconducting states that enables the calculation of thermodynamic quantities for...

Change in Density of States in a Resonant Tunneling Structure Due to a Scattering Center in the Well. (1998)

Pandey, L. N., George, Thomas F., Rustgi, M. L., Sahu, D.

The change in density of states and transmission resonance energy shifts have been calculated for a double-barrier single-quantum-well heterostructure by placing a scattering center in the middle of...

Sahu, D., Namperumalsamy, P, Hilton, G., De Sousa, N. F

BACKGROUND—Spontaneous bullous serous retinal detachment (RD) with subretinal exudation complicating idiopathic central serous chorioretinopathy (ICSC) is a rare and infrequently described clinical...
