Superconductivity is a fascinating state of matter where materials conduct electricity without any resistance, often defying our everyday expectations of how energy behaves. Researchers in this field explore the quantum mechanics behind these phenomena, seeking new materials that can operate at higher temperatures or under more practical conditions. This work holds the promise of revolutionizing everything from power grids to medical imaging devices, making the invisible world of quantum physics feel increasingly tangible and useful.

Motivated by recent experiments on rhombohedral graphene, this paper demonstrates that the evolution between a chiral superconductor and a composite Fermi liquid generally proceeds through an intermediate stable Landau Fermi liquid phase for weak attractive interactions, rather than via a direct continuous transition.
This study reveals that compressive strain along the -axis in underdoped HgBaCuO induces a significant elongation of the Cu-O bond and generates a strain-driven, nearly commensurate two-dimensional charge correlation with a wave vector near (0.5, 0, 0) that is independent of superconductivity and resembles resonating valence bond predictions.
Through Langevin dynamics simulations of vortex nanocrystals in superconductors, this study reveals that confinement induces a healing effect of topological defects at the edges during crystallization, resulting in a stationary defect profile that quantitatively matches experimental data and offers general insights into the physical properties of confined soft condensed matter nanocrystals.
Using low-temperature magnetic force microscopy on high-purity tantalum, this study achieves direct imaging and active manipulation of flux structures in type-I superconductors, revealing topological hysteresis and demonstrating reversible dynamic reconfigurations like stripe-grid transitions under AC excitation.
This paper proposes that the unexpectedly high critical temperature observed in high-pressure MnB is driven by altermagnetic spin fluctuations rather than conventional electron-phonon coupling, leading to an extended- pairing symmetry.
This study demonstrates that substituting Fe with Mn in PrFeAs(O,F) acts as a potent magnetic impurity that suppresses superconductivity and induces insulating-like behavior, while also revealing the enhanced robustness of superconductivity in Pr-based systems compared to other rare-earth variants.
By independently tuning strain and oxygen content in (La,Pr)NiO films, researchers identified a two-step mechanism for superconductivity driven by the delocalization of Ni and O orbitals, which suppresses long-range magnetic order while preserving robust short-range magnons.
The paper argues that rotating a thin superconducting cylinder can substantially increase its critical temperature by leveraging rotational energy storage mechanisms—specifically, the decoupling of Cooper pairs from mechanical rotation to generate magnetic fields and the interaction of normal components with external magnetic fields—to promote condensate formation.
This paper proposes that disorder-driven plateau transitions of anyon-flux composite fermions explain the emergence of superconductivity and re-entrant integer quantum anomalous Hall phases in doped twisted MoTe fractional quantum anomalous Hall insulators, successfully linking experimental observations to theoretical predictions derived from integer quantum Hall transition physics.
Using low-temperature scanning tunneling microscopy, researchers discovered that the van der Waals metal CeTe3 hosts versatile, competing antiferromagnetic charge-ordered states (stripe and checkerboard) tunable by modest magnetic fields, revealing a rich, strongly correlated electronic landscape that extends beyond weak-coupling descriptions and offers a new platform for engineering tunable nanoscale quantum states.
