Raman Response of the Charge Density Wave in Cuprate Superconductors
Moallison F. Cavalcante, S. Bag, I. Paul +3
We study the Raman response, for and light-polarization symmetries, of the charge density wave phase appearing in the underdoped region of cuprate superconductors…
Quench dynamics of the Kondo effect: transport across an impurity coupled to interacting wires
Moallison F. Cavalcante, Rodrigo G. Pereira, Maria C. O. Aguiar
We study the real-time dynamics of the Kondo effect after a quantum quench in which a magnetic impurity is coupled to two metallic Hubbard chains. Using an effective field theory a…
Formation of spin and charge ordering in the extended Hubbard model during a finite-time quantum quench
Isaac M. Carvalho, Helena Bragança, Walber H. Brito +1
We investigate the formation of charge and spin ordering by starting from a non-interacting state and studying how it evolves in time under a Hamiltonian with finite electronic int…
Quench dynamics and relaxation of a spin coupled to interacting leads
Helena Bragança, Moallison F. Cavalcante, R. G. Pereira +1
We study a quantum quench in which a magnetic impurity is suddenly coupled to Hubbard chains, whose low-energy physics is described by Tomonaga-Luttinger liquid theory. Using the t…
Anderson localization effects on doped Hubbard model
Nathan Giovanni, Marcello Civelli, Maria C. O. Aguiar
We derive the disorder vs. doping phase diagram of the doped Hubbard model via Dynamical Mean Field Theory combined with Typical Medium Theory, which allows the description of both…
Odd-frequency superconductivity in dilute magnetic superconductors
Flávio L. N. Santos, Vivien Perrin, François Jamet +5
We show that dilute magnetic impurities in a conventional superconductor give origin to an odd-frequency component of superconductivity, manifesting itself in Yu-Shiba-Rusinov band…
