Correlation-driven Lifshitz transition at the emergence of the pseudogap phase in the two-dimensional Hubbard model

open access: yes, 2018
We study the relationship between the pseudogap and Fermi-surface topology in the two-dimensional Hubbard model by means of the cellular dynamical mean-field theory.

Laser‐assisted in situ fabrication of atomically thin Ga2O3 films for dielectric applications

open access: yesFlexMat, EarlyView.
A confinement template‐assisted squeeze method, in conjunction with laser‐assisted in situ oxidation, facilitates fabrication of centimeter‐scale and atomically thin gallium oxide films from liquid gallium under room temperature conditions. This low‐damage approach avoids thermal degradation of sensitive materials and supports high‐performance field ...

Pseudogap phase of cuprate superconductors confined by Fermi surface topology

open access: yesNature Communications, 2017
High-temperature superconductors exhibit pseudogap behaviour that remains of unknown origin, despite many years of intensive study. Here the authors study the onset of the pseudogap under pressure, providing evidence that it requires a hole-like Fermi ...

Pseudogap in cuprate and organic superconductors

open access: yes, 2012
We study the pseudogap present in cuprate and organic superconductors. We use the dynamical cluster approximation (DCA), treating a cluster embedded in a bath.

Intrinsic Thermal Transport Properties of ZrB2 From Room Temperature to Melting Point

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Zirconium diboride (ZrB2) is a promising material for extreme‐environment applications, yet its intrinsic high‐temperature thermophysical behavior remains uncertain: Experiments are highly sensitive to processing conditions, simulations omit key mechanisms, and both rarely reach ultrahigh temperatures. Here, we predict the thermal conductivity

Pseudogap and preformed pairs in the imbalanced Fermi gas in two dimensions

open access: yesNew Journal of Physics, 2012
The physics of the pseudogap state is intimately linked with the pairing mechanism that gives rise to superfluidity in quantum gases and to superconductivity in high- T _c cuprates, and therefore, both in quantum gases and in superconductors, the ...

Non-equilibrium Transport in the Strange Metal and Pseudogap phases of the Cuprates

open access: yes, 2013
We propose that the non-equilibrium current measured in the $a-b$ plane of an underdoped cuprate (in either the strange metal or pseudogap regime) in contact with either an overdoped cuprate or a standard Fermi liquid can be used diagnose how different ...

Topological order in the pseudogap metal [PDF]

open access: yesProceedings of the National Academy of Sciences, 2018
Significance The copper oxide-based high-temperature superconductors display a mysterious “pseudogap” metal phase at temperatures just above the critical temperature in a regime of low hole density. Extensive experimental and numerical studies have yielded much information on the nature of the electron corrections, but a fundamental ...

Universal Electronic‐Structure Relationship Governing Intrinsic Magnetic Properties in Permanent Magnets

open access: yesAdvanced Functional Materials, Volume 36, Issue 30, 13 April 2026.
Permanent magnets derive their extraordinary strength from deep, universal electronic‐structure principles that control magnetization, anisotropy, and intrinsic performance. This work uncovers those governing rules, examines modern modeling and AI‐driven discovery methods, identifies critical bottlenecks, and reveals electronic fingerprints shared ...

Pseudogap temperature and effects of a harmonic trap in the BCS-BEC crossover regime of an ultracold Fermi gas

open access: yes, 2011
We theoretically investigate excitation properties in the pseudogap regime of a trapped Fermi gas. Using a combined $T$-matrix theory with the local density approximation, we calculate strong-coupling corrections to single-particle local density of ...
