Dirac points and topological phases in correlated altermagnets
Lorenzo Del Re
We explore a two-dimensional Hubbard model adapted to host altermagnetic states. Utilizing Hartree-Fock (HF) and dynamical mean field theory (DMFT), we uncover that the magnetic so…

Thermodynamic Stability at the Two-Particle Level
A. Kowalski, M. Reitner, L. Del Re +6
We show how the stability conditions for a system of interacting fermions that conventionally involve variations of thermodynamic potentials can be rewritten in terms of one- and t…

Long-Time Error-Mitigating Simulation of Open Quantum Systems on Near Term Quantum Computers
Brian Rost, Lorenzo Del Re, Nathan Earnest +3
We study an open quantum system simulation on quantum hardware, which demonstrates robustness to hardware errors even with deep circuits containing up to two thousand entangling ga…
