Telegraph noise effects on two charge-qubits in double quantum dots
A. Ayachi, W. Ben Chouikha, S. Jaziri +1
We analyze theoretically the decoherence of two interacting electrons in a double self-assembled quantum dot due to a random telegraph noise. For this purpose we have examined the…
The 1D Heisenberg antiferromagnet model by the variation after projection method
Aziz Rabhi, Marta Brajczewska, Peter Schuck +2
The 4 sites and 8 sites 1D anti-ferromagnetic Heisenberg chains in the Jordan-Wigner representation are investigated within the standard Hartree-Fock and RPA approaches, both in th…
Role of the cooling rate in the stability of the superconducting phase of (TMTSF)_2ClO_4
S. Haddad, I. Sfar, S. Charfi-Kaddour +1
The noncentrosymmetric ClO anions of the organic superconductor (TMTSF)ClO order below 24K. The size of domains where the anions are ordered is substantially dependent…
Self-Consistent Random Phase Approximation - Application to the Hubbard Model for finite number of sites
Mohsen Jemai, Peter Schuck, Jorge Dukelsky +1
Within the 1D Hubbard model linear closed chains with various numbers of sites are considered in Self Consistent Random Phase Approximation (SCRPA). Excellent results with a minima…
Restoration of broken symmetries in Self-Consistent RPA
A. Rabhi, P. Schuck, R. Bennaceur +2
It is shown that the Self-Consistent RPA (SCRPA) approach allows in a very natural way to restore symmetries, spontaneously broken on the mean field level. This is achieved via the…
