Here, the Holstein-Hubbard model at one electron per site filling – a realistic model of superconductivity that includes electron correlation and electron-phonon coupling – is solved exactly in a relevant region of its phase diagram, by numerical simulations based on quantum Monte Carlo. Previous attempts were limited by exponential complexity in the number of electrons.

Topological order and spontaneous symmetry breaking are typically thought of as paradigmatic, yet antipodal, phenomena in correlated quantum matter. Here, the authors show instead that they can concomitantly act to determine the ground-state properties of interacting systems, providing a novel angle for the discussion of topological phenomena and parafermions in one-dimensional fermionic systems. They show that topological Majorana modes can coexist with ℤ spontaneous symmetry breaking by discussing a lattice model of one-dimensional spinless fermions and thoroughly characterize the presence of nontopological parafermions.

Nonlocal (topological) order and local (Landau-type) order are often viewed as opposing principles. Here, the authors study strongly interacting quantum wires that exhibit hybrid order, composed of local Ising magnetization and a topological order parameter. Based on an exact mapping of the corresponding strongly interacting electronic Hamiltonian onto ℤ parafermions, they show that the system can be in a hybrid phase which is distinct from the topological and from the Ising phase. Moreover, the system has remarkable similarities to superconducting hybrid devices built from fractional quantum Hall edge states, which can host parafermions useful for quantum computation.

Topological phases of matter that have an insulating bulk and robust gapless boundary states can exist both in static materials and when system parameters are changed periodically in time. In the latter case, the periodic driving can lead to so called “anomalous” topological phases. Here, the authors show that, in the newly introduced higher-order topological insulators, anomalous phases can exist even if the system is static, and provide an example of such behavior using a two-dimensional model with topological corner charges. This work opens up the possibility of studying anomalous phases without the inherent difficulties associated with time-periodic changes of a material, such as the risk that it will “heat up” due to the driving field and lose its topological features.
