Fast Real-Axis Eliashberg Calculations: Full-bandwidth solutions beyond the constant density of states approximation
Alejandro Simon, James Shi, Dominik Spath +10
Experimentally relevant signatures of superconductivity require access to real-frequency quantities, such as the spectral functions, optical response, and transport properties, yet…
Ultrafast dynamics and light-induced superconductivity from first principles
Alejandro Simon, James Shi, Eva Kogler +9
Experiments on superconducting materials have unveiled unique emergent properties when they are driven far from equilibrium. However, a quantitative first-principles treatment that…
Inverse Isotope Effect in the Ternary Perovskite Hydride SrPdH/D: A Signature of Quantum Zero-Point Fluctuations
Wencheng Lu, Mihir Sahoo, Roman Lucrezi +9
Guided by first-principles calculations, we demonstrate superconductivity in the ternary perovskite hydride SrPdH, synthesized at low pressure. Structural characterization…
Prediction and Synthesis of MgPtH: A Metallic Complex Transition Metal Hydride Stabilized at Ambient Pressure
Wencheng Lu, Michael J. Hutcheon, Mads F. Hansen +13
The low-pressure stabilization of superconducting hydrides with high critical temperatures (s) remains a significant challenge, and experimentally verified superconducting hyd…
Ab initio modeling of nonequilibrium dynamics in superconducting detectors and qubits
Alejandro Simon, Reed Foster, Mihir Sahoo +7
Nonequilibrium quasiparticle (QP) and phonon dynamics are central to the operation of superconducting devices. Superconducting detectors, such as the superconducting nanowire singl…
