Title in Portuguese
Comportamento crítico de um gás de Bose-Einstein magnetizado
Keywords in Portuguese

Abstract in Portuguese
Investigamos neste trabalho o comportamento crítico de um gás de bósons neutros com spin S na presença de um campo magnético uniforme. Os expoentes críticos são calculados como função da dimensionalidade d do sistema e do parâmetro δ do espectro E(K) ∼ Kδ de urna partícula. O comportamento crítico é examinado nas condições de volume constante e de pressão constante. Estabelecemos as relações entre os novos expoentes críticos e os calculados por Gunton e Buckingharn para o gás ideal de Bose-Einstein sem spin

Abstract in English
The critical behavior of a d-dimensional ideal gas of uncharged bosons with spin S and spectrum of a single particle given by E(K) ∼ Kδ in a uniform magnetic field is examined. The critical exponents are calculated as a function of the dimensionality of the systems and the parameter δ for both constant volume and constant pressure. We establish the relationship between the new critical exponents with those calculated by Gunton and Buckingham for a spineless Bose-Einstein gas
