The repulsive Hubbard model has been immensely useful in understanding strongly
correlated electron systems and serves as the paradigmatic model of the field. Despite its …

The Hubbard model is the simplest model of interacting fermions on a lattice and is of similar
importance to correlated electron physics as the Ising model is to statistical mechanics or the …

Electronic nematicity, in which rotational symmetry is spontaneously broken by electronic
degrees of freedom, has been demonstrated as a ubiquitous phenomenon in correlated …

The transition metal kagome lattice materials host frustrated, correlated and topological
quantum states of matter,,,,,,,–. Recently, a new family of vanadium-based kagome metals …

Understanding the competition between superconductivity and other ordered states (such as
antiferromagnetic or charge-density-wave (CDW) state) is a central issue in condensed …

The discovery of several electronic orders in kagome superconductors AV3Sb5 (A means K,
Rb, Cs) provides a promising platform for exploring unprecedented emergent physics …

The distinctive electronic structure found at interfaces between materials can allow
unconventional quantum states to emerge. Here we report on the discovery of …

In this work, we exhaust all the spin space symmetries, which fully characterize collinear,
noncollinear, and commensurate spiral as well as incommensurate spiral magnetism, etc …

Supersolids are states of matter that spontaneously break two continuous symmetries:
translational invariance owing to the appearance of a crystal structure and phase invariance …

High-T c superconductivity with possible T c≈ 80 K has been reported in the single crystal of
La 3 Ni 2 O 7 under high pressure. Based on the electronic structure given by the density …
