Convergence of the conformal Ward identity in the derivative expansion approximation
Jorge Ibañez, Matthieu Tissier, Gonzalo De Polsi
Conformal invariance is expected to be an emergent property of many systems in their critical regime. However, approximation schemes generically spoil this property. This is in par…

Conformal Invariance of the large- limit of the universality class
Santiago Cabrera, Gonzalo De Polsi, Adam Rançon +1
Conformal symmetry is expected to be realized in many equilibrium statistical mechanical systems at criticality. Although this is certainly true in two-dimensional systems, the thr…

Spin Splitter and Inverse Effects in Altermagnetic Hybrid Structures
Nicolás Sigales, Tim Kokkeler, Gonzalo de Polsi +1
We provide a theoretical description of diffusive charge and spin transport in hybrid devices containing altermagnets. Based on recently derived drift--diffusion equations for coup…
