Thermodynamic Green functions in theory of superconductivity

, 2006
A general theory of superconductivity is formulated within the thermodynamic Green function method for various types of pairing mediated by phonons, spin fluctuations, and strong Coulomb correlations in the Hubbard and t-J models.

Macroscopic phase separation of superconductivity and ferromagnetism in Sr0.5Ce0.5FBiS2-xSex revealed by μSR [PDF]

, 2017
The compound Sr0.5Ce0.5FBiS2 belongs to the intensively studied family of layered BiS2 superconductors. It attracts special attention because superconductivity at T sc = 2.8 K was found to coexist with local-moment ferromagnetic order with a Curie ...

Uranium Doped Gallium Nitride Epitaxial Thin Films

Advanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
Uranium was controllably added to gallium nitride using molecular beam epitaxy. The uranium atoms segregated into vertically oriented regions with higher doping levels. Concentrations up to a few percent were achieved without showing significant degradation in the crystalline quality or optical characteristics. Low electrical resistivity was maintained

Twist Engineering of Hybrid 2D van der Waals‐Transition Metal Oxide Membranes

Advanced Physics Research, Volume 5, Issue 6, June 2026.
The integration of transition metal oxide membranes with 2D van der Waals materials offers exciting opportunities to study new interfacial phenomena. These interactions can create complex moiré patterns that change the materials' properties. Understanding these interactions, influenced by symmetry and distortion, poses significant challenges and ...

Vortex matter in U ( 1 ) × U ( 1 ) × Z 2 phase-separated superconducting condensates

, 2014
We study the properties of vortex solutions and magnetic response of two-component U(1)×U(1)×Z2 superconductors, with phase separation driven by intercomponent density-density interaction. Such a theory can be viewed arising from the breakdown of SU(2) symmetry by a biquadratic interaction between the components of the field.

Enhancement of superconductivity near the ferromagnetic quantum critical point in UCoGe [PDF]

, 2009
We report a high-pressure single crystal study of the superconducting ferromagnet UCoGe. Measurements of the ac susceptibility and resistivity under pressures up to 2.2 GPa show ferromagnetism is smoothly depressed and vanishes at a critical pressure p(c)

Dimensionality‐Driven Emerging Phenomena in Hybrid Metal Halides

Small Structures, Volume 7, Issue 6, June 2026.
Emergent Phenomena Governed by Octahedral Connectivity and Dimensionality. Hybrid metal halides are unique among semiconductors in that their inorganic octahedral networks can be rationally assembled in 3D, 2D, 1D, and 0D forms, enabling dimensionality to assist as a powerful control knob over structure, electronic properties, excitations, and ...

Superconductivity: Heike's heritage

, 2011
A century ago, Heike Kamerlingh Onnes discovered superconductivity. And yet, despite the conventional superconductors being understood, the list of unconventional superconductors is growing — for which unconventional theories may be ...

Superconductivity and magnetic order in the noncentrosymmetric half-Heusler compound ErPdBi [PDF]

, 2013
We report superconductivity at Tc = 1.22 K and magnetic order at TN = 1.06\ K in the semimetallic noncentrosymmetric half-Heusler compound ErPdBi. The upper critical field, Bc2, has an unusual quasi-linear temperature variation and reaches a value of 1.6
