Flat bands are massively degenerate sets of quantum mechanical states with minimal energy dispersion in the momentum space. Since their inception in lattice models more than three decades ago, the ...

The geometry of an object indicates its shape or the relationship of its parts to each other. Did you know that the electrons in solids also have geometric structures? In quantum mechanics, an ...

Flat-band lattice systems represent a class of engineered structures in which one or more energy bands are completely dispersionless. This intriguing characteristic arises from the delicate interplay ...

In semiconductor physics, the flat band potential is a critical parameter that influences the properties and behavior of semiconductors in contact with other materials, such as electrolytes or p-n ...

A new technical paper titled “Topological Flat-Band-Driven Metallic Thermoelectricity” was published by researchers at TU Wien, Los Alamos National Lab, Flatiron Institute and others. “Materials where ...

A research team found a way to measure the quantum distance of Bloch states in solids by applying magnetic field. The geometry of an object indicates its shape or the relationship of its parts to each ...
