Em sua primeira edição, esse livro pretendia apresentar as ideias básicas do cálculo diferencial e integral aos estudantes do primeiro ano dos cursos de física e engenharia. Definir o que é essencial não é tarefa fácil e alguns tópicos impo

A phenomenological approach to the description of temperature-concentration phase diagrams in lyotropic liquid crystals is proposed. It is based on the coupling of the power expansions associated with the concentration variable, and the symmetry-brea

We present in this paper a way to perform the mapping of the spin-1 Blume–Capel model into a random-cluster model, and analyze thermodynamic properties of the former model in terms of geometric properties of clusters generated in the random-cluster

We explore the properties of the non-commutative Grassmann algebra to obtain the high-temperature expansion of the grand canonical partition function for self-interacting fermionic systems. As an application, we consider the anharmonic fermionic osci

We study the renormalization of the field theory that describes the Lifshitz point (LP). Our motivation was an old controversy on the order-${\ensuremath{\epsilon}}^{2}$ values of critical exponents for this multicritical point. First we analyze the

We study the phase diagram of the mean-field spin-1 Ising ferromagnet in a uniform magnetic field H and a random crystal field Δ i , with probability distribution P ( Δ i ) = pδ ( Δ i − Δ ) + (1 − p ) δ ( Δ i ). We analyse the effects of r

We propose a Monte Carlo cluster algorithm which eliminates metastability in first-order phase transitions of spin-1 models. As an example, we apply it to the Blume-Emery-Griffiths model. Our prescription for growing clusters accelerates the decay of

We show rigorously that the ground state of a quantum chain with competing ferromagnetic nearest and antiferromagnetic next nearest interactions undergoes a transition from ferromagnetic to helical type, in the isotropic case, for a certain value of
