The authors address a long-standing puzzle of pseudogap phenomenon observed in high temperature cuprates. Based on numerical calculations for the Hubbard model with analytic considerations, they find that a combination of strong-coupling ...

Unified energy law for fluctuating density wave orders in cuprate pseudogap phase
The origin of the pseudogap in the cuprates and how it is related to the mechanism of their superconductivity has been a topic of long standing debate. Here, the authors suggest that the pseudogap is governed by a unified energy law the basis for which ...

We study the magnetic and spectral properties of a single-band Hubbard model for the infinite-layer nickelate compound LaNiO2. As spatial correlations turn out to be the key ingredient for understanding its physics, we use two complementary extensions of

Observation of pseudogap in MgB2 [PDF]
Pseudogap phase in superconductors continues to be an outstanding puzzle that differentiates unconventional superconductors from the conventional ones (BCS-superconductors). Employing high resolution photoemission spectroscopy on a highly dense conventional superconductor, MgB2, we discover an interesting scenario. While the spectral evolution close to

Pseudogap in elemental plutonium [PDF]
Electronic correlations associated with incipient magnetism have long been recognized as an important factor in stabilizing the largest atomic volume $\delta$ phase of plutonium, yet their strength compared to those in the rare earths and neighboring actinides in the Periodic Table has largely remained a mystery.

Probing d-wave pairing correlations in the pseudogap regime of the cuprate superconductors via low-energy states near impurities [PDF]
The issue of probing the pseudogap regime of the cuprate superconductors, specifically with regard to the existence and nature of superconducting pairing correlations of d-wave symmetry, is explored theoretically.

Hidden Pseudogap and Excitation Spectra in a Strongly Coupled Two-Band Superfluid/Superconductor
We investigate single-particle excitation properties in the normal state of a two-band superconductor or superfluid throughout the Bardeen–Cooper–Schrieffer (BCS) to Bose–Einstein-condensation (BEC) crossover, within the many-body T-matrix approximation ...

The problem of the pseudogaps in oxide HTSC is analyzed by means of the off-diagonal propagators, in analogy with the method of Nambu in superconductivity. We conjecture that the small pseudogap is obtained as the Fock diagram and the large pseudogap as the total off-diagonal self-energy (which is the sum of the Hartree diagram and the Fock diagram ...
