Symmetries of the quasi-1d Bechgaard salts superconducting state in an applied magnetic field
N. Belmechri, G. Abramovici, M. Heritier
We investigate the possible superconducting pairing symmetries which would account for the latest experimental results on the Bechgaard salts. Using a renormalization group (R.G) t…
Magnetic field induced singlet - triplet phase transition in quasi one-dimensional organic superconductors
N. Belmechri, G. Abramovici, M. Heritier +2
We propose a theoretical model of quasi-one-dimensional superconductors, with attractive electron-electron interactions dominant in the singlet d-wave channel and sub-dominant in t…
Renormalization Group calculations with k|| dependent couplings in a ladder
G. Abramovici, J. C. Nickel, M. Heritier
We calculate the phase diagram of a ladder system, with a Hubbard interaction and an interchain coupling . We use a Renormalization Group method, in a one loop expansion,…
New Magnetic-Field-Induced Macroscopic Quantum Phenomenon in High- Cuprates: Confined Field-Induced Density Waves in the Superconducting State
G. Varelogiannis, M. Heritier
We reveal a novel macroscopic quantum phenomenon induced by a magnetic field. It corresponds to the {\it non-integer quantization of the superfluid density} in a superconductor wit…
New magnetic-field-induced macroscopic quantum phenomenon in a superconductor with gap nodes
Georgios Varelogiannis, Michel Heritier
High- superconductivity is unconventional because the gap is not isotropic as in simple metals but has symmetry with lines of nodes. In a fascinating thermal tra…
Competing phases in the high field phase diagram of (TMTSF)ClO
S. Haddad, S. Charfi-Kaddour, C. Nickel +2
A model is presented for the high field phase diagram of (TMTSF)ClO, taking into account the anion ordering, which splits the Fermi surface in two bands. For strong enough…
In Search of Exact Solutions
Michel Heritier
Many-body systems, such as electrons flowing in a superconductor, are among the most difficult theoretical problems to study. A new family of exactly solvable models may offer some…
Coexistence of Superconductivity and Spin Density Wave orderings in the organic superconductor (TMTSF)_2PF_6
T. Vuletic, P. Auban-Senzier, C. Pasquier +4
The phase diagram of the organic superconductor (TMTSF)_2PF_6 has been revisited using transport measurements with an improved control of the applied pressure. We have found a 0.8…
