Tighter upper bounds on the critical temperature of two-dimensional superconductors and superfluids from the BCS to the Bose regime
Tingting Shi, Wei Zhang, C. A. R. Sá de Melo
We discuss standard and tighter upper bounds on the critical temperature of two-dimensional (2D) superconductors and superfluids versus particle density or filling factor…
Higher order derivative operators as quantum corrections
L. H. C. Borges, F. A. Barone, C. A. M. de Melo +1
In this paper we propose a non-minimal, and ghost free, coupling between the gauge field and the fermionic one from which we obtain, perturbatively, terms with higher order derivat…
Introduction to Regge Calculus for Gravitation
R. R. Cuzinatto, C. A. M. de Melo, C. Naldoni de Souza
With the theory of general relativity, Einstein abolished the interpretation of gravitation as a force and associated it to the curvature of spacetime. Tensorial calculus and diffe…
Staircase in magnetization and entanglement entropy of spin squeezed condensates
H. M. Bharath, M. S. Chapman, C. A. R. Sá de Melo
Staircases in response functions are associated with physically observable quantities that respond discretely to continuous tuning of a control parameter. A well-known example is t…
Non-perturbative Solution to the Quantum Interaction Problem via Schwinger's Action Principle
C. A. M. de Melo, B. M. Pimentel, J. A. Ramirez
The most realistic situations in quantum mechanics involve the interaction between two or more systems. In the most of reliable models, the form and structure of the interactions g…
Algebraic Theory of Measurement Processes in Quantum Systems
C. A. M. de Melo, B. M. Pimentel, J. A. Ramirez
Here we deal in a pedagogical way with an approach to construct an algebraic structure for the Quantum Mechanical measurement processes from the concept of \emph{Measurement Symbol…
