This study addresses the challenge of quench protection in insulated REBCO conductors for fusion energy applications by demonstrating through 1D THEA modeling that optimizing copper stabilizers and employing a thermally coupled, deoxygenated REBCO superconducting quench detector (SQD) effectively limit hotspot temperatures and enable faster detection, respectively.
This study predicts that applying a 4.5% uniaxial tensile strain to carbon nanotubes significantly enhances their electron-phonon coupling and electronic density of states, resulting in a high-temperature superconducting critical temperature of 162 K.
This study demonstrates that reducing the pulse duration in YBCO bridges from milliseconds to nanoseconds significantly increases the onset current for oxygen electromigration by lowering local temperatures, thereby shifting the process toward an athermal regime with important implications for memristor operation and thermomagnetic stability.
Using an advanced functional renormalization group approach that resolves full frequency dependence and self-energy feedback, this study systematically analyzes the Hubbard-Holstein model to reveal how self-energy effects enhance -wave superconductivity at high phonon frequencies while causing a breakdown of Migdal-Eliashberg theory and a reduction of -wave superconductivity at low frequencies, thereby clarifying the complex interplay of intertwined fluctuations and isotope effects.
This theoretical study using a five-orbital LCAO approximation and Kondo double electron exchange successfully reproduces the experimentally observed supermodulation of the superconducting order parameter in BiSrCaCuO, providing strong evidence that super-exchange interactions mediated by Cu4s orbital hybridization constitute the electron pairing mechanism in optimally doped cuprates.
This study identifies that Pr doping at the Ba site in YBCO7 induces a specific lattice breathing-mode distortion that pins charge-stripe walls to dopant columns, thereby stabilizing three-dimensional charge order through targeted ionic substitution.
Using unbiased simulations of interacting hardcore bosons on a ladder, this study demonstrates that photoirradiation can melt phase-reversed charge stripes to enhance superfluidity and condensate fraction, offering a strategy to engineer time-dependent perturbations that release suppressed orders in unconventional superconductors.
This study reveals that twisted bilayer MoTe hosts an intervalley superconducting phase emerging from a non-Abelian fractional spin Hall insulator, driven by the condensation of charge- non-Abelian anyons and supported by both exact diagonalization and field-theoretic analyses.
This study characterizes the structural and microwave properties of pulsed laser-deposited FeSe thin films at 8 GHz under a 12 T magnetic field, comparing their temperature-dependent surface resistance and magnetic field resilience to Fe(Se,Te) films to evaluate their potential for dark matter haloscope applications.
This paper proposes a theoretical framework for generating zero-field superconducting vortices and pinning Majorana zero modes in correlated Rashba systems by leveraging the inhomogeneous magnetization gradients induced by exchange-coupled magnetic islands, offering a viable experimental route to trap these composite excitations without external magnetic fields.
