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.

This paper reports the fabrication of boron-doped, ultra-thin carbon nanotube networks within zeolite pores that exhibit characteristic signatures of high-temperature superconductivity with a critical temperature between 220 and 250 K, alongside a giant pressure effect that further elevates this transition temperature.
This paper presents theoretical and experimental evidence for a new phase of matter called multimodal superfluidity in neutron-rich systems, characterized by the coexistence of s-wave pairs, p-wave entangled double pairs, and quartets, which is predicted to occur in various fermionic systems and has significant implications for the structure and dynamics of neutron star crusts.
This paper demonstrates that depositing granular aluminum on Ge/SiGe heterostructures induces a hard superconducting gap with exceptional magnetic field resilience, enabling the observation of Zeeman-split Yu-Shiba-Rusinov states and tunable g-tensors essential for hole spin-based hybrid quantum devices.
This study reveals that the dynamics of charge-density-wave puddles in 2-NbSe give rise to a novel Fano-coupled phonon-CDW hybrid mode, characterized by a low-frequency overdamped oscillation that emerges below 17 K and highlights the critical role of lattice pinning and electronic correlations in stabilizing incommensurate CDW order.
Motivated by recent experiments, this paper derives general expressions for photonic heat transport through a Josephson junction in a dissipative environment, demonstrating that the heat current remains sensitive to Josephson coupling on the insulating side with opposite behaviors for series and parallel configurations, while also predicting heat rectification properties.
This paper develops a covariant Lagrangian framework for time-reversal symmetry-broken Weyl superconductors to demonstrate that FFLO pairing spontaneously breaks axial symmetry, generating a pseudo-scalar Nambu-Goldstone mode that couples to gauge fields via the axial anomaly and predicts additional vector and axial-vector collective excitations analogous to mesonic modes in QCD.
This paper predicts that confining light in infrared cavities can control the Ginzburg-Landau stiffness of superconductors by renormalizing the Cooper-pair kinetic mass through photon-mediated repulsive interactions, an effect that is particularly significant in low-temperature materials and tunable via cavity length.
This paper proposes that nematic order in multilayer graphene enhances superconductivity by breaking symmetry to reshape Bloch wavefunctions and amplify the quantum metric, thereby significantly boosting pairing strength through the quantum geometric Kohn-Luttinger mechanism.
This paper argues that the reported magnetic field-induced changes in the lattice structure and charge density wave intensity of RbVSb, previously interpreted as evidence of piezomagnetism, are actually artifacts caused by STM tip reconfiguration and instrumental distortions rather than intrinsic sample properties.
This paper presents a method to map the individual positions of surface two-level-systems (TLS) on a superconducting transmon qubit by utilizing local electric fields from on-chip gate electrodes, revealing that TLS density is significantly enhanced near the Josephson junction leads rather than the larger capacitor area, thereby guiding future qubit design and fabrication improvements.
