Understanding the electron pairing in hole-doped cuprate superconductors has been a
challenge, in particular because the “normal” state from which it evolves is unprecedented …

The recent discovery of high-temperature superconductivity in La 3 Ni 2 O 7 offers a fresh
platform for exploring unconventional pairing mechanisms. Starting with the basic argument …

Describing all aspects of the physics of transition metal compounds, this book provides a
comprehensive overview of this unique and diverse class of solids. Beginning with the basic …

A concept—quantum order—is introduced to describe a new kind of orders that generally
appear in quantum states at zero temperature. Quantum orders that characterize the …

Unravelling competing orders emergent in doped Mott insulators and their interplay with
unconventional superconductivity is one of the major challenges in condensed matter …

The square-lattice Hubbard and closely related tJ models are considered as basic
paradigms for understanding strong correlation effects and unconventional …

In strongly correlated quantum materials, the behavior of charge carriers is dominated by
strong electron-electron interactions. These can lead to insulating states with spin order, and …

It is argued that the electron stripes as found in correlated oxides have to do with an
unrecognized form of order. The manifestation of this order is the robust property that the …

We investigate the bilayer nickelates as a platform to realize the symmetric mass generation
(SMG) insulator, a featureless Mott insulator that arises due to the Lieb-Schultz-Mattis (LSM) …

Angle-resolved photoemission spectroscopy (ARPES) has revealed peculiar properties of
mobile dopants in correlated antiferromagnets (AFMs). But, describing them theoretically …
