Efficient simulation of second-order phase transitions in quantum anharmonic materials
Andrea Baldanza, Lorenzo Monacelli
When a crystal undergoes a second-order structural phase transition, such as in ferroelectrics, Peierls, and charge-density waves, the diverging fluctuations of the order parameter…

Spin Response of a Magnetic Monopole and Quantum Hall Response in Topological Lattice Models through Local Invariants and Light
Karyn Le Hur, Andrea Baldanza
Here, we elaborate on and develop the geometrical approach introduced in K. Le Hur, Physics Reports 1104 1-42 (2025) between the magnetic monopole created from a radial field, quan…
