The presence of different electronic orders other than superconductivity populating the
phase diagram of cuprates suggests that they might be the key to disclose the mysteries of …

In many quantum materials, strong electron correlations lead to the emergence of new states
of matter. In particular, the study in the last decades of the complex phase diagram of high …

A softening of phonon dispersion has been observed experimentally in underdoped cuprate
superconductors at the charge-density-wave (CDW) ordering wave vector. Interestingly, the …

The quantum origin of the cuprate pseudogap is a central conundrum of condensed matter
physics. Although many symmetry-broken scenarios were previously proposed, universal …

Pair density waves, identified by Cooper pairs with finite center-of-mass momentum, have
recently been observed in copper oxide based high T c superconductors (cuprates). A …

The ladder-chain compound (Sr, Ca) 14 Cu 24 O 41 is a semiconductor at ambient pressure,
but becomes a bulk superconductor above the pressure of about 3 GPa. Since the …

The superconducting phase of the HgBa 2 CuO 4+ δ (Hg-1201) and HgBa 2 Ca 2 Cu 3 O 8+
δ (Hg-1223) cuprates has been investigated by Raman spectroscopy under hydrostatic …

To address the issues of superconducting and charge properties in high-T $ _c $ cuprates,
we perform a quantum Monte Carlo study of an extended three-band Emery model, which …

We followed step by step the transition from an antiferromagnetic (AFM) Mott insulator to a
superconducting (SC) metal in the Bi 2 Sr 2 CaCu 2 O 8+ δ (Bi-2212) cuprate using …

Exploring the origin of the pseudogap is important for the understanding of superconductivity
in cuprates. Here we report a systematical experimental study on the phonon vibrational …
