Unscreened Polaron Ordering Against High Electron Density on Mechanically Cleaved Surfaces of WO3 (001) Films

Small, Volume 21, Issue 39, October 2, 2025.
Unscreened high‐density polarons are discovered in a metallic WO3 (001) 2DEG, stabilized by surface oxygen vacancies and c(2 × 2) reconstruction. ARPES and STM/STS reveal polaron formation and ordering, supported by first‐principles calculations. This work opens new avenues for exploring collective polaron phenomena, including bipolaron interactions ...

Voltage‐Induced Hysteretic Resistance in Nematic Order of SmFeAsO

Aggregate, Volume 6, Issue 9, September 2025.
Electronic origin of nematicity revealed! This study uncovers a unique voltage‐driven hysteresis effect in the SmFeAsO's nematic phase through the advanced point‐contact spectroscopy. A bias voltage drives the point contact through antiferromagnetic and structural transitions via the ballistic Joule heating effect, revealing a distinctive hysteretic ...

Superfluid density of states and pseudogap phenomenon in the BCS-BEC crossover regime of a superfluid Fermi gas

, 2010
We investigate single-particle excitations and strong-coupling effects in the BCS-BEC crossover regime of a superfluid Fermi gas. Including phase and amplitude fluctuations of the superfluid order parameter within a $T$-matrix theory, we calculate the ...

Orientation‐Dependent Upper Critical Magnetic Field and Density of State for Uranium Ditelluride

Advanced Physics Research, Volume 4, Issue 8, August 2025.
This study investigates the orientation‐dependent upper critical magnetic field (HC2) and the density of states (DOS) in the unconventional superconductor UTe2. These results reveal an anisotropic HC2, with distinct critical fields along different crystallographic axes, highlighting the role of electronic correlations and spin‐triplet pairing.

Field-dependent specific heat of the canonical underdoped cuprate superconductor $$\hbox {YBa}_2\hbox {Cu}_4\hbox {O}_8$$ YBa 2 Cu 4 O 8

Scientific Reports, 2020
The cuprate superconductor $$\hbox {YBa}_2\hbox {Cu}_4\hbox {O}_8$$ YBa 2 Cu 4 O 8 , in comparison with most other cuprates, has a stable stoichiometry, is largely free of defects and may be regarded as the canonical underdoped cuprate, displaying marked

Disentangling Cooper-pair formation above Tc from the pseudogap state in the cuprates

, 2010
The discovery of the pseudogap in the cuprates created significant excitement amongst physicists as it was believed to be a signature of pairing, in some cases well above the room temperature.

Development of Electroconductive Polypyrrole‐Polycaprolactone and Poly(3,4‐Ethylenedioxythiophene)‐poly(Styrenesulfonate)‐Polyethylene Oxide Fibrous Scaffolds by Pressurised Gyration for Cardiac Tissue Engineering Applications

Macromolecular Materials and Engineering, Volume 310, Issue 8, August 2025.
This study pioneers the fabrication of electroconductive cardiac scaffolds using pressurised gyration with the conductive polymers PPy and PEDOT:PSS. The resulting scaffolds exhibit optimal electroconductive and physicochemical properties, closely matching those of native cardiac tissue.

Entanglement and Classical Correlations at the Doping-Driven Mott Transition in the Two-Dimensional Hubbard Model

PRX Quantum, 2020
Tools of quantum information theory offer a new perspective to characterize phases and phase transitions in interacting many-body quantum systems. The Hubbard model is the archetypal model of such systems and can explain rich phenomena of quantum matter ...

Magnetic order in the pseudogap phase of high-$T_C$ superconductors

, 2005
One of the leading issues in high-$T_C$ superconductors is the origin of the pseudogap phase in underdoped cuprates. Using polarized elastic neutron diffraction, we identify a novel magnetic order in the YBa$_2$Cu$_3$O$_{6+x}$ system.
