Two dimensional XXZ-Ising model on square-hexagon lattice
J. S. Valverde, Onofre Rojas, S. M. de Souza
We study a two dimensional XXZ-Ising on square-hexagon (4-6) lattice with spin-1/2. The phase diagram of the ground state energy is discussed, shown two different ferrimagnetic sta…
Phase diagram of the asymmetric tetrahedral Ising-Heisenberg chain
J. S. Valverde, Onofre Rojas, S. M. de Souza.
The asymmetric tetrahedron is composed by all edges of tetrahedron represented by Ising interaction except one, which has a Heisenberg type interaction. This asymmetric tetrahedron…
Relativistic particle dynamics in D=2+1
J. S. Valverde, M. Pazetti
We propose a SUSY variant of the action for a massless spinning particles via the inclusion of twistor variables. The action is constructed to be invariant under SUSY transformatio…
Electromagnetic field at Finite Temperature: A first order approach
R. Casana, B. M. Pimentel, J. S. Valverde
In this work we study the electromagnetic field at Finite Temperature via the massless DKP formalism. The constraint analysis is performed and the partition function for the theory…
Bose-Einstein Condensation and Free DKP field
R. Casana, V. Ya. Fainberg, B. M. Pimentel +1
The thermodynamical partition function of the Duffin-Kemmer-Petiau theory is evaluated using the imaginary-time formalism of quantum field theory at finite temperature and path int…
Equivalence of Many-Photon Green Functions in DKP and KGF Statistical Quantum Field Theories
V. Ya. Fainberg, B. M. Pimentel, J. S. Valverde
We prove the equivalence of many-photon Green functions in statistical quantum field Duffin-Kemmer-Petiau (DKP) and Klein-Gordon-Fock (KGF) theories using functional path integral…
