Band-Insulator-Metal-Mott-Insulator transition in the half--filled ionic-Hubbard chain
G. I. Japaridze, R. Hayn, P. Lombardo +1
We investigate the ground state phase diagram of the half-filled repulsive Hubbard model in the presence of a staggered ionic potential , using the continuum-limi…
Nature of the metal-insulator transition in the half--filled t-t' Hubbard chain
G. I. Japaridze, R. M. Noack, D. Baeriswyl
We study the quantum phase transition from an insulator to a metal realized at t'=t'_c > 0.5t in the ground state of the half-filled Hubbard chain with both nearest-neighbor (t) an…
Magnetization plateau in the S=1/2 spin ladder with alternating rung exchange
G. I. Japaridze, E. Pogosyan
We have studied the ground state phase diagram of a spin ladder with alternating rung exchange in a magnetic filed, in the limit where t…
The intuitionistic fragment of computability logic at the propositional level
Giorgi Japaridze
This paper presents a soundness and completeness proof for propositional intuitionistic calculus with respect to the semantics of computability logic. The latter interprets formula…
