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 identifies the excited transverse magnetic cavity mode responsible for coherent terahertz emission from a nearly square stack of intrinsic Josephson junctions by combining tunable emission observations, wedge-type interferometer power measurements, and scattering spectrum simulations.
This paper demonstrates the mutual synchronization of macroscopic Josephson oscillations across multiple stacks of intrinsic Josephson junctions in BiSrCaCuO through polarization analysis, proving their coupling via a superconducting substrate and outlining a pathway for developing high-power terahertz sources.
This paper demonstrates a compact, chip-integrated terahertz imaging system utilizing high-temperature superconducting Josephson plasma emitters to achieve high-contrast, nondestructive imaging of diverse concealed objects, thereby validating its potential for broad applications in security, medicine, and materials science.
Through numerically-exact quantum Monte Carlo simulations, this study demonstrates that the Su-Schrieffer-Heeger electron-phonon coupling model induces significantly higher superconducting critical temperatures than the Holstein model, particularly in strong coupling regimes, by simultaneously enhancing electron pairing and Cooper pair phase coherence.
This paper presents an SU(2)×U(1) generalization of the Ginzburg-Landau theory for spin-triplet ferromagnetic superconductivity, describing a system with massive photons and non-Abelian magnons, massless neutral magnons, and a Higgs scalar field that exhibits unique features such as non-Abelian Meissner effects, dual conserved supercurrents, and distinct magnetic and spin vortices and monopoles.
This study predicts that hydrogenated trilayer metal tetraborides (MBH; M=Be, Mg, Ca, Al) are dynamically stable, exhibit multi-gap superconductivity driven by strong electron-phonon coupling, and possess tunable transition temperatures up to 64 K, with CaBH showing the highest potential for high- applications.
Using density matrix renormalization group (DMRG) simulations motivated by recent ultracold atom experiments, this study reveals that the two-leg Lieb ladder Hubbard model transitions from a ferrimagnetic Mott insulator at half-filling to a Luttinger liquid at lower fillings, with a distinct superconducting Luther-Emery phase exhibiting dominant -wave pairing emerging in a narrow window near the critical filling of .
This paper characterizes approximate vortex structures of atomic Fermi superfluids on a spherical surface under an effective monopole field by employing two Ginzburg-Landau-based constructions—geometric scaffolding and free-energy minimization—which yield vortex configurations that converge to the planar Abrikosov lattice limit as the number of vortices increases.
By combining scanning tunneling microscopy with Ginzburg-Landau analysis, this study reveals that the kagome superconductor CsVSb hosts two distinct, coexisting electronic nematic orders—one tied to charge density waves and another to V- orbital distortions—that exhibit complex interplay, temperature-dependent alignment, and persistence even when long-range CDW order is suppressed.
By combining first-principles calculations with singular-mode functional renormalization group analysis, this study reveals that the interlayer Ni-Ni distance in La3Ni2O7/LaAlO3 thin films critically tunes the ground state between C-type and G-type spin density waves, with -wave superconductivity emerging in the intermediate regime, thereby explaining ambient-pressure superconductivity and predicting its suppression under applied pressure.
