Effective Fermion Mass in Relativistic and Non-Relativistic Systems
Heron Caldas
Electrons interact strongly with their environment. The result of these interactions is, most of the time, encoded in an effective mass. In non-relativistic systems, as in condense…
Competing effective interactions of Dirac electrons in the Spin-Fermion system
E. C. Marino, Lizardo H. C. M. Nunes
Recently discovered advanced materials, such as heavy fermions, frequently exhibit a rich phase diagram suggesting the presence of different competing interactions. A unified descr…
Non-perturbative corrections to the quasiparticle velocity in graphene
Heron Caldas
Relativistic fermionic systems have physical quantities calculated by well stablished quantum electrodynamic prescriptions. In the last few years there has been an enormous interes…
Induced p-wave superconductivity without spin-orbit interactions
Fernanda Deus, Mucio A. Continentino, Heron Caldas
The study of Majorana fermions is of great importance for the implementation of a quantum computer. These modes are topologically protected and very stable. It is now well known th…
Nesting and lifetime effects in the FFLO state of quasi-one-dimensional imbalanced Fermi gases
Heron Caldas, Mucio A. Continentino
Motivated by the recent experimental realization of a candidate to the Fulde-Ferrell (FF) and the Larkin-Ovchinnikov (LO) states in one dimensional (1D) atomic Fermi gases, we stud…
The competition between the superconducting and the excitonic phases on doped Dirac electronic systems
Lizardo H. C. M. Nunes, R. L. S. Farias, E. C. Marino
We investigate the competition between the superconducting and the excitonic phases on Dirac electrons on a bipartite planar lattice. The conditions for the appearance of supercond…
Quantum normal-to-inhomogeneous superconductor phase transition in nearly two-dimensional metals
Heron Caldas, Mucio A. Continentino
In multi-band systems, electrons from different orbitals coexist at the Fermi surface. An attractive interaction among these quasi-particles gives rise to inter-band or hybrid pair…
Competing superconducting, magnetic and charge orderings in the AF Heisenberg-Kondo lattice with Dirac electrons
E. C. Marino, Lizardo H. C. M. Nunes
Many recently discovered advanced materials, such as high-Tc cuprates, iron pnictides and several heavy-fermions, exhibit a rich phase diagram suggesting the presence of different…
An Effective Field Theory Model for One-Dimensional Chains: Effects at Finite Chemical Potential, Temperature and External Zeeman Magnetic Field
Heron Caldas
In this work we use an effective field theory model to investigate doped chains under the influence of an external constant Zeeman magnetic field , at zero and fi…
Temperature effects on the magnetization of quasi-one-dimensional Peierls distorted materials
Heron Caldas
It is shown that temperature acts to disrupt the magnetization of Peierls distorted quasi-one-dimensional materials (Q1DM). The mean-field finite temperature phase diagram for the…
Asymmetrically Doped Polyacetylene
Heron Caldas
Doped one-dimensional (1D) conjugated polymers, such as polyacetylene, have a conductivity of some metals, like copper. We show that when this polymer is asymmetrically doped, unex…
Temperature Effects in a Fermi Gas with Population Imbalance
Heron Caldas, A. L. Mota
We investigate temperature effects in a Fermi gas with imbalanced spin populations. From the general expression of the thermal gap equation we find, in {\it weak coupling limit}, a…
