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 study reports the synthesis of single-crystalline quasi-two-dimensional Kondo lattice CeSnSb and demonstrates a rare inverse magnetic melting effect where low in-plane magnetic fields restore translational and rotational symmetries by transforming a fragile antiferromagnetic order and cluster glass ground state into a polarized paramagnetic phase.
This study reports the successful synthesis and characterization of noncentrosymmetric YPtSi single crystals, revealing a weak-coupling, two-gap superconducting state with an enhanced Kadowaki-Woods ratio and the absence of charge density wave transitions, which are further supported by first-principles calculations.
Using state-of-the-art functional renormalization group studies, this paper reports the discovery of a genuine primary pair density wave (PDW) phase in a two-orbital kagome Hubbard model, driven by sublattice and orbital polarized Bloch states that suppress zero-momentum pairing in favor of finite-momentum Cooper pairs, with potential realization in materials like CsCrSb and cold atom systems.
This paper evaluates the potential of iron-based superconducting multilayers for Superconducting Radio-Frequency applications by analyzing their surface barrier and resistance characteristics to demonstrate their superior performance over bulk niobium and conventional superconductors in terms of maximum magnetic field tolerance, surface resistance, and power loss, while also discussing future prospects for increasing operating temperatures.
This paper presents the design and experimental validation of a top-loading point-contact spectroscopy probe integrated with a dilution refrigerator, featuring in-situ sample exchange and piezo-driven nanopositioning to enable stable, high-resolution spectroscopic measurements of superconductors and quantum materials at temperatures as low as 30 mK.
Using determinant quantum Monte Carlo simulations, this study reveals that the triangular lattice optical Su-Schrieffer-Heeger model exhibits distinct doping-dependent behaviors, including a symmetry-breaking bond-order-wave transition at half-filling and a potential -wave superconducting phase at three-quarters filling for large phonon energies, while showing no enhanced magnetic correlations.
This study disentangles the electronic and phononic contributions to high-temperature superconductivity in X2MH6 hydrides, revealing that electronic factors—specifically X-H bond distance, hydrogen electron localization, and projected density of states—dominate Tc and provide a robust figure of merit for designing new superconductors, while pressure exerts competing effects by enhancing electronic contributions but weakening phononic ones.
The paper introduces BosonFlow, a unified C++ codebase that implements dynamic functional renormalization group and parquet equations within the single-boson exchange formalism to compute full dynamic vertices and self-energies for correlated fermion systems using a truncated unity framework.
This paper demonstrates that in a one-dimensional monitored superconducting chain, the competition between pairing-induced entanglement growth and measurement-induced suppression can lead to a counterintuitive regime where steady-state entanglement increases with measurement rate, although this enhancement remains finite in the thermodynamic limit.
This study employs multimodal terahertz spectroscopy to establish that compressively strained (La,Pr)NiO films are bulk superconductors with disordered -wave pairing that coexists with a distinct correlated normal state exhibiting a pseudogap.
