On the Physical Meaning of the Geometric Factor and the Effective Thickness in the Montgomery Method

F. S. Oliveira, L. M. S. Alves, M. S. da Luz +2

Simulations carried out with COMSOL software in order to study the electrical resistivity of rectangular samples are reported. The comparison of the results with the four-probe met…

A Simple and Precise Way to Determine Electrical Resistivity of Isotropic Conductors: Simplifying the Four-Probe Method

L. M. S. Alves, F. S. Oliveira, E. C. Romão +2

COMSOL Multiphysics software is used to describe the behavior of the electrical resistivity of several samples with rectangular shape typically used in the Montgomery method. The s…

On the Fermi gas, the Sommerfeld fine structure constant, and the electron-electron scattering in conductors

C. A. M. dos Santos, M. S. da Luz, F. S. Oliveira +1

Electrical energy is considered as a fundamental parameter for inclusion in Fermi gas theory, in addition to thermal energy. It is argued that electrical energy can move some elect…

On the Order Parameter of the Continuous Phase Transition in the Classical and Quantum Mechanical limits

C. A. M. dos Santos, F. S. Oliveira, M. S. da Luz +1

The mean field theory is revisited in the classical and quantum mechanical limits. Taking into account the boundary conditions at the phase transition and the third law of the ther…

Interplay between antiferrodistortive, ferroelectric and superconducting instabilities in Sr_{1-x}Ca_{x}$TiO_{3-δ}

B. S. de Lima, M. S. da Luz, F. S. Oliveira +11

SrTiO undergoes a cubic-to-tetragonal phase transition at 105K. This antiferrodistortive transition is believed to be in competition with incipient ferroelectricity. Substitu…

Analytical BPS Maxwell-Higgs vortices

R. Casana, M. M. Ferreira, E. da Hora +1

We have established a prescription for the calculation of analytical vortex solutions in the context of generalized Maxwell-Higgs models whose overall dynamics is controlled by two…

Stoichiometry, structure, and transport in the quasi-one-dimensional metal, Li(0.9)Mo(6)O(17)

J. L. Cohn, P. Boynton, J. S. Trivino +4

A correlation between lattice parameters, oxygen composition, and the thermoelectric and Hall coefficients is presented for single-crystal Li(0.9)Mo(6)O(17), a quasi-one-dimensiona…
