Quantized Photocurrents in Gapless Topological Matter
Byunghoon Kim, Tenzin Norden, Mohammad Yahyavi +17
The quantum Hall effect establishes that topology can fix a material response to integer multiples of fundamental constants when an energy gap isolates the relevant symmetry-protec…
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…
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…
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…
High-pressure stabilization of Mg2IrH7: Structural proximity to high-Tc superconductivity
Shubham Sinha, Wencheng Lu, Mads F. Hansen +14
MgIrH is a metastable complex metal hydride with a predicted superconducting transition temperature as high as 170 K at ambient pressure. Following the synthesis of isomorp…
Polar enhancement of optical nonlinearities and domain-driven second harmonic contrast in bismuth telluro-halide van der Waals crystals
Kevin W. C. Kwock, Tenzin Norden, Thomas P. Darlington +11
The BiTeX family of polar van der Waals (vdW) semiconductors offers a unique platform for exploring the interplay between polar crystalline structure and nonlinear optical phenomen…
