Decoding Superconductivity in La $_3$ Ni $_2$ O $_{7-\delta}$ Thin Films via Ozone-Driven Structure and Oxidation Tuning

This study utilizes scanning transmission electron microscopy and electron energy loss spectroscopy to correlate the structural polymorphs and oxygen stoichiometry of epitaxial La $_3$ Ni $_2$ O $_{7-\delta}$ thin films with their superconducting properties, establishing a framework for stabilizing superconductivity in bilayer nickelates through precise ozone-driven structural and oxidation tuning.

Strong Electron-Phonon Coupling and Multiband Superconductivity in Hexagonal BP3 Monolayer

First-principles calculations combined with anisotropic Migdal-Eliashberg theory predict that the stable hexagonal BP3 monolayer is a strongly coupled, multiband two-dimensional superconductor with a transition temperature of 9.7 K, driven by significant electron-phonon interactions involving B-P bonding and pz orbitals.

Adiabatic self-vibrations of a movable Cooper-pair box generated by inelastic Andreev tunneling

This paper proposes a scheme for generating self-sustained two-dimensional vibrations in a movable Cooper-pair box by harnessing inelastic Andreev tunneling within an adiabatic limit, where the system's nonlinearity naturally saturates the amplitude without requiring external feedback.

Hidden Universal Metal in Cuprate Superconductors

This paper proposes a phenomenological model for cuprate superconductors based on nuclear relaxation data, identifying a "universal metal" state where the critical temperature is directly linked to the copper nuclear relaxation rate and explaining the doping-dependent anisotropy and pseudogap phenomena through a crossover into a strange metal regime.

Ultrafast decoupling of the pseudogap from superconductivity in a pressurized cuprate

Using ultrafast optical spectroscopy under high pressure, researchers demonstrate that the pseudogap and superconductivity in underdoped Bi $_2$ Sr $_2$ CaCu $_2$ O $_{8+\delta}$ are distinct phenomena that evolve independently, with the pseudogap energy gap suppressing while the superconducting dome persists until a dimensional crossover and eventual insulating transition occur at extreme pressures.

Microscopic mechanism for resonant light-enhanced pair correlations in K $_3$ C $_{60}$

This paper establishes a purely electronic mechanism for the resonant light-enhanced pair correlations observed in K $_3$ C $_{60}$ , demonstrating through advanced numerical simulations that a symmetry-constrained two-photon pathway drives the system into a superconducting-like state, thereby confirming that the experimental 10 THz resonance stems from coherent pair formation rather than improved metallicity.

Type-II superconductivity in the Dirac semimetal PdTe2

This study reveals that mosaic crystals of the Dirac semimetal PdTe2 exhibit type-II superconductivity with a fully gapped s-wave order parameter, driven by disorder-induced flux line lattice formation, thereby establishing the material as a model system for exploring the interplay between non-trivial topology and tunable superconducting states.

Emergence of the unexpected charge-density-wave phase driven by artificial gauge field in three-leg Bose-Hubbard ladder

This study reveals that a uniform artificial gauge field in a half-filled three-leg Bose-Hubbard ladder induces an unexpected charge-density-wave phase and reentrant CDW-vortex-CDW transitions, driven by a strong competition between vortex and density-wave orders that defies typical expectations for such bosonic ladder systems.

Statistical Signatures of Majorana Zero Modes in Disordered Topological Superconductor Antidot Vortices

This paper establishes that the variance of the probability density for Majorana zero modes is twice that of Caroli-de Gennes-Matricon states due to the former's real wave functions, offering a distinct statistical signature detectable via scanning tunneling microscopy in disordered antidot vortices.

Reduced pair breaking from extended disorder in unconventional superconductors: implications to 4Hb-TaS $_2$

This paper demonstrates that extended disorder potentials, such as chalcogen vacancies, significantly suppress pair-breaking rates in unconventional superconductors compared to standard point defects, thereby explaining the robustness of superconductivity in disordered materials like 4Hb-TaS $_2$ despite high resistivity.
