  • The coexistence of different magnetic and electronic phases often occurs in materials with complex chemical compositions, allowing for the study of competitive, collaborative, or emergent phenomena. Here, the authors demonstrate such behaviour in ultrathin Fe films on a Rh(001) substrate.

  • The phase diagram of twisted bilayer graphene as a function of twist angle remains not fully understood. Here, the authors theoretically demonstrate that it exhibits an angle-tuned quantum critical point of Gross-Neveu type using quantum Monte Carlo.

  • Deconfined quantum critical points separate two phases with different broken symmetries, which puts them beyond the standard Landau theory of phase transitions. Here the authors present a model with a monopole-free deconfined quantum critical point, making it more amenable to detailed numerical studies.

  • Stretching a sheet of graphene could induce a superconducting state. Similar strain-induced superconductivity may be realized at the interface between a topological crystalline insulator and a trivial band insulator.
