Quantized Photocurrents in Gapless Topological Matter
Byunghoon Kim, Tenzin Norden, Mohammad Yahyavi +17
The authors experimentally observe a quantized circular photogalvanic effect in the chiral topological semimetal Rh0.95Ni0.05Si, providing an all‑optical analogue of the quantum Ha…
Anharmonic lattice dynamics and superconductivity in strained bulk and surface niobium
Mihir Ranjan Sahoo, Roman Lucrezi, Pedro Nunes Ferreira +5
Using first-principles calculations, we investigate how homogeneous strain and crystallographic surface orientation modify the vibrational and superconducting properties of niobium…
First-principles evidence for conventional superconductivity in a quasicrystal approximant
Pedro N. Ferreira, Roman Lucrezi, Sangmin Lee +7
Quasicrystals (QCs) host long-range order without translational symmetry, a regime in which the very foundations of BCS theory are not straightforwardly applicable, yet experiments…
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…
Ambient-pressure 151-K superconductivity in HgBa2Ca2Cu3O8+δ via pressure quench
Liangzi Deng, Thacien Habamahoro, Artin Safezoddeh +10
Superconductivity has been a vigorously researched topic since its discovery in 1911. Raising the superconducting transition temperature (Tc) has been the main driving force behind…
