The Gor'kov and Melik-Barkhudarov correction to an imbalanced Fermi gas in the presence of impurities
Heron Caldas, S. Rufo, M. A. R. Griffith
The effects of induced interactions are calculated in both clean and dirty situations, for balanced and imbalanced Fermi gases. We investigate the effects of nonmagnetic impurities…
Enhancing long-range order in disordered two-band s-wave superconductors
Heron Caldas, S. Rufo, M. A. R. Griffith
We investigate the effects of disorder in a hybridized two-dimensional two-band s-wave superconductor model. The situation in which electronic orbitals form these bands with angula…
Effects of anisotropic correlations in fermionic zero-energy bound states of topological phases
M. A. R. Griffith, E. Mamani, L. Nunes +1
Topological phases of matter have been used as a fertile realm of intensive discussions about fermionic fractionalization. In this work, we study the effects of anisotropic superco…
Multi-critical Behavior in Topological Phase Transitions
S. Rufo, Nei Lopes, Mucio A. Continentino +1
Topological phase transitions can be described by the theory of critical phenomena and identified by critical exponents that define their universality classes. This is a consequenc…
Machine learning topological phases in real space
N. L. Holanda, M. A. R. Griffith
We develop a supervised machine learning algorithm that is able to learn topological phases of finite condensed matter systems from bulk data in real lattice space. The algorithm e…
Kramers' doublet ground state in topological Kondo insulators
M. A. Griffith, M. A. Continentino, T. O. Puel
We consider the simplest variant of a Kondo insulator where a doublet of localized -electrons hybridizes with spin-degenerate conduction electrons. We analyse the symmetries of…
