Quantum Rotors on the AB Chain with Competing Interactions
Antônio S. F. Tenório, R. R. Montenegro-Filho, M. D. Coutinho-Filho
We present the ground state phase diagram of quantum-rotor chains with competing interactions (frustration) calculated through cluster variational mean field approaches.…
Quantum phase transitions in alternating spin-(1/2, 5/2) Heisenberg chains
A. S. F. Tenório, R. R. Montenegro-Filho, M. D. Coutinho-Filho
The ground state spin-wave excitations and thermodynamic properties of two types of ferrimagnetic chains are investigated: the alternating spin-1/2 spin-5/2 chain and a similar cha…
Dispersion forces between an atom and a perfectly conducting wedge
T. N. C. Mendes, F. S. S. Rosa, A. Tenorio +1
We consider the interaction between an electrically polarizable atom in its fundamental state and a wedge constituted by two semi-infinite perfectly conducting plates. Using a form…
