One of the leading challenges of condensed matter physics in the past few decades is an
understanding of the high-temperature copper-oxide superconductors. Although the d-wave …

The existence of charge-density-wave (CDW) correlations in cuprate superconductors has
now been established. However, the nature of the CDW ground state has remained …

Charge-density wave order is now understood to be a widespread feature of underdoped
cuprate high-temperature superconductors, although its origins remain unclear. While …

In underdoped cuprate superconductors, the Fermi surface undergoes a reconstruction that
produces a small electron pocket, but whether there is another, as yet, undetected portion to …

The observation of a reconstructed Fermi surface via quantum oscillations in hole-doped
cuprates opened a path towards identifying broken symmetry states in the pseudogap …

Our knowledge of the ground state of underdoped hole-doped cuprates has evolved
considerably over the last few years. There is now compelling evidence that, inside the …

Complex oxides show a rich variety of functionalities through their strong coupling to the
lattice, electron, orbital, and spin degrees of freedom not only at oxide heterointerfaces but …

The last few years have seen significant experimental progress in characterizing the copper-
based hole-doped high temperature superconductors in the regime of low hole density, p …

The odd-parity multipole is an emergent degree of freedom, leading to spontaneous
inversion symmetry breaking. The odd-parity multipole order may occur by forming …

High-temperature superconductive (SC) cuprates exhibit not only a SC phase, but also
competing orders, suppressing superconductivity. Charge order (CO) has been recognized …
