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.

By investigating the temperature-dependent magnon damping in the metallic van der Waals ferromagnet via inelastic neutron scattering, the study demonstrates that magnon damping can serve as a new probe for the interplay between Kondo coupling and thermal fluctuations in magnetically ordered -electron systems.
Using density matrix renormalization group calculations, this paper demonstrates that pair-density-wave (PDW) order in the Kondo-Heisenberg chain emerges via a Lifshitz transition characterized by a four-Fermi-point dispersion and in-gap bound states, which can be modeled as a generalized - model with effective next-nearest-neighbor hopping.
Using unbiased projector quantum Monte Carlo simulations on a bilayer model, this study demonstrates that loop-current fluctuations can drive the emergence of time-reversal-symmetry-breaking superconductivity, establishing an intrinsic connection between spontaneous loop currents and unconventional superconducting states.
This paper proposes a model where a magnetic impurity bridging two s-wave superconducting wires creates two "free" zero-energy Majorana fermions—one at the impurity and one at the edge—protected by the physics of a two-channel Kondo interaction within a Luther-Emery liquid.
The paper demonstrates that different variational wave function architectures can yield nearly identical energies while predicting conflicting physical states, concluding that systematic improvements in accuracy and correlation tracking are essential to resolve competing orders in the Hubbard model.
This paper demonstrates a scalable, non-volatile superconducting memory device that uses exchange-field gap engineering in a vertical spin-valve architecture to achieve low-power, high-efficiency magnetoresistance for cryogenic and quantum computing applications.
This paper uses first-principles calculations to theoretically predict that a hypothetical cubic phase of could exhibit strong-coupling superconductivity with a critical temperature of up to 73.7 K at ambient pressure.
This paper proposes a theoretical framework for realizing robust, tunable Majorana bound states at the corners of a two-dimensional semi-Dirac system by inducing effective p-wave pairing in its anisotropic edge states through the interplay of Rashba spin-orbit coupling, a Zeeman field, and s-wave superconductivity.
This paper describes the development and upgrading of a specialized measurement setup at DESY designed to investigate the superconducting properties of niobium cavities by analyzing resonance frequency shifts and quality factor changes during the transition from a superconducting to a normal-conducting state.
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.
