Fundamental limitations of single-particle Green's-function zeroes as probes of many-body topology
Emile Pangburn, Olivier Gingras
We show that topological invariants constructed from single-particle Green's functions (GFs) cannot reliably diagnose the topology of interacting many-body states. Using coupled in…
Abinit 2025: New Capabilities for the Predictive Modeling of Solids and Nanomaterials
Matthieu J. Verstraete, Joao Abreu, Guillaume E. Allemand +71
Abinit is a widely used scientific software package implementing density functional theory and many related functionalities for excited states and response properties. This paper p…
Frequency-dependent Inter-pseudospin Solutions to Superconducting Strontium Ruthenate
Olivier Gingras, Nikita Allaglo, Reza Nourafkan +2
The lasting puzzle of the superconducting order parameter of SrRuO calls for theoretical studies that include seldom-considered effects. Here we include spin-orbit coupling…
Superconductivity in Correlated Multi-Orbital Systems with Spin-Orbit Coupling: Coexistence of Even- and Odd-Frequency Pairing and the Case of Strontium Ruthenate
Olivier Gingras, Nikita Allaglo, Reza Nourafkan +2
The superconducting order parameter of strontium ruthenate is the center of a lasting puzzle calling for theoretical studies that include the seldom-considered effects of spin-orbi…
Superconducting Symmetries of SrRuO from First-Principles Electronic Structure
Olivier Gingras, Reza Nourafkan, André-Marie S. Tremblay +1
Although correlated electronic-structure calculations explain very well the normal state of SrRuO, its superconducting symmetry is still unknown. Here we construct the spin…
