Dispersion of the neutron resonance in cuprate superconductors
Andrey V. Chubukov, Boldizsar Janko, Oleg Tchernyshyov
We argue that recently measured downward dispersion of the neutron resonance peak in cuprate superconductors is naturally explained if the resonance is viewed as a spin-1 collectiv…
Fingerprints of spin-fermion pairing in cuprates
Ar. Abanov, Andrey V. Chubukov, Jörg Schmalian
We demonstrate that the feedback effect from bosonic excitations on fermions, which in the past allowed one to verify the phononic mechanism of a conventional, wave superconduc…
Where is the pi particle?
O. Tchernyshyov, M. R. Norman, A. V. Chubukov
We discuss the interplay of particle-particle and particle-hole spin-triplet channels in high-T_c superconductors using a quasiparticle dispersion motivated by angle-resolved photo…
Spectral function and conductivity in the normal state of the cuprates: a spin fluctuation study
R. Haslinger, Andrey V. Chubukov, Ar. Abanov
We study the spectral function and the optical conductivity for a system of fermions interacting with their collective spin fluctuations (the spin-fermion model…
Quantum-critical superconductivity in underdoped cuprates
Ar. Abanov, Andrey V. Chubukov, Jörg Schmalian
We argue that the pseudogap phase may be an attribute of the non-BCS pairing of quantum-critical, diffusive fermions near the antiferromagnetic quantum critical point. We derive an…
Spin-fermion model near the quantum critical point: one-loop renormalization group results
Ar. Abanov, Andrey V. Chubukov
We consider spin and electronic properties of itinerant electron systems, described by the spin-fermion model, near the antiferromagnetic critical point. We expand in the inverse n…
SIN and SIS tunneling in cuprates
Ar. Abanov, Andrey V. Chubukov
We calculate the SIN and SIS tunneling conductances for the spin-fermion model. We argue that at strong spin-fermion coupling, relevant to cuprates, both conductances have dip feat…
