Classical and quantum analysis of a heterotriatomic molecular Bose-Einstein-condensate model
Tonel, Arlei Prestes; Kuhn, Carlos Claiton Noschang; Santos Filho, Gilberto Nascimento; Foerster, Angela; Roditi, Itzhak; Santos, Zeila Virginia Torres (2009) [Artigo de periódico]We investigate an integrable Hamiltonian modeling a heterotriatomic molecular Bose-Einstein condensate. This model describes a mixture of two species of atoms in different proportions, which can combine to form a triatomic ... -
Phase diagrams of three-component attractive ultracold fermions in one dimension
Kuhn, Carlos Claiton Noschang; Foerster, Angela (2012) [Artigo de periódico]We investigate trions, paired states and quantum phase transitions in one-dimensional SU(3) attractive fermions in external fields by means of the Bethe ansatz formalism. Analytical results for the ground state energy, ... -
Quantum criticality of spin-1 bosons in a one-dimensional harmonic trap
Kuhn, Carlos Claiton Noschang; Guan, Xi-Wen; Foerster, Angela; Batchelor, Murray T. (2012) [Artigo de periódico]We investigate universal thermodynamics and quantum criticality of spin-1 bosons with strongly repulsive density-density and antiferromagnetic spin-exchange interactions in a one-dimensional harmonic trap. From the equation ... -
Universality class of quantum criticality for strongly repulsive spin-1 bosons with antiferromagnetic spin-exchange interaction
Kuhn, Carlos Claiton Noschang; Guan, Xi-Wen; Foerster, Angela; Batchelor, Murray T. (2012) [Artigo de periódico]Using the thermodynamic Bethe ansatz equations we study the quantum phase diagram, thermodynamics, and criticality of one-dimensional (1D) spin-1 bosons with strongly repulsive density-density and antiferromagnetic ...
