Analytic Integration of the Lambert W Cosmic Fluid Model H(z) Formula
Ken Roberts, S. R. Valluri, Francisco Javier Garcia-Sánchez +1
The Lambert (LW) model for the cosmic fluid equation of state was proposed by S. Saha and K. Bamba in 2019-2020. A recent (early 2026) paper by Dubey, et al, carries out a new…
Solar Cells, Lambert W and the LogWright Functions
Prabhat Lankireddy, Sibibalan Jeevanandam, Aditya Chaudhary +3
Algorithms that calculate the current-voltage (I-V) characteristics of a solar cell play an important role in processes that aim to improve the efficiency of a solar cell. I-V char…
Lambert W Lines and Finite Square Well Sensors
Ken Roberts, Najeh Jisrawi, J. Jeyasitharam +3
The bound state energies of a 1-dimensional finite quantum square well (FSW) can be determined using a geometric method, involving a smooth mapping between two copies of the comple…
An Analytic Study of the Wiedemann-Franz Law and the Thermoelectric Figure of Merit
Aakash Yadav, PC Deshmukh, Ken Roberts +2
Advances in optimizing thermoelectric material efficiency have seen a parallel activity in theoretical and computational advances. In the current work, it is shown that the calcula…
On Calculating the Current-Voltage Characteristic of Multi-Diode Models for Organic Solar Cells
Ken Roberts, S. R. Valluri
We provide an alternative formulation of the exact calculation of the current-voltage characteristic of solar cells which have been modeled with a lumped parameters equivalent circ…
Band structure and transport studies of half Heusler compound DyPdBi: An efficient thermoelectric material
S. Krishnaveni, M. Sundareswari, P. C. Deshmukh +2
The discovery of Heusler alloys has revolutionized the research field of intermetallics due to the ease with which one can derive potential candidates for multifunctional applicati…
A Robust Approximation to a Lambert-Type Function
Ken Roberts
The function , where denotes the Lambert W function, is the solution to the equation . It appears in various problem sit…
Solution of the quantum finite square well problem using the Lambert W function
Ken Roberts, S. R. Valluri
We present a solution of the quantum mechanics problem of the allowable energy levels of a bound particle in a one-dimensional finite square well. The method is a geometric-analyti…
The Lambert W Function, Laguerre Polynomials, and the Zeros of the QCD Partition Function
Ken Roberts, S. R. Valluri
We study solutions of a transcendental equation for the complex chemical potential at which a random-matrix QCD model can undergo a phase transition at zero mass. An explicit solut…
