Semiconductor moiré superlattices represent a rapidly develo** area of engineered
photonic materials and a new platform to explore correlated electron states and quantum …

In condensed-matter systems, higher temperatures typically disfavour ordered phases,
leading to an upper critical temperature for magnetism, superconductivity and other …

In the 1950s, Pomeranchuk predicted that, counterintuitively, liquid 3He may solidify on
heating. This effect arises owing to high excess nuclear spin entropy in the solid phase …

The group of moiré graphene superconductors keeps growing, and by now it contains
twisted graphene multilayers as well as untwisted stacks. We analyze here the contribution …

Strong coupling between light and elementary excitations is emerging as a powerful tool to
engineer the properties of solid-state systems. Spin-correlated excitations that couple …

The polarizability of twisted bilayer graphene, due to the combined effect of electron–hole
pairs, plasmons, and acoustic phonons, is analyzed. The screened Coulomb interaction …

We present a framework for understanding the cascade transitions and the Landau level
degeneracies of twisted bilayer graphene. The Coulomb interaction projected onto narrow …

The interplay of dynamical correlations and electronic ordering is pivotal in sha** phase
diagrams of correlated quantum materials. In magic-angle twisted bilayer graphene …

Collective excitations contain key information regarding the electronic order of the ground
state of strongly correlated systems. Various collective modes in the spin and valley isospin …

We report on finite-size exact-diagonalization calculations in a Hilbert space defined by the
continuum-model flat moiré bands of magic angle twisted bilayer graphene. For moiré band …
