Yttrium Superhydrides Revisited: Advanced Experimental and Theoretical Studies of YH, YH and YH
Dmitrii V. Semenok, Pedro N. Ferreira, Di Zhou +10
Yttrium polyhydrides are benchmark materials in high-pressure superconductivity, yet several key properties of the Y-H system remain insufficiently characterized. Here we combine c…
Ab initio thermodynamic statistical modeling of the miscibility gap and the metal-insulator phase transition in SrTiVO
Luka Wibmer, Chiara Ostendorf, Dominik Spath +3
The substitutional alloy SrTiVO interpolates between the band insulator SrTiO and the correlated metal SrVO, exhibiting a composition-driven metal--insulato…
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…
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…
Stability and Superconductivity of Ternary Polyhydrides
Dmitrii V. Semenok, Di Zhou, Wuhao Chen +8
We review five years of experimental and theoretical attempts (2020-2025) to enhance the superconducting critical temperature ($\textit{T$_c$}$) of hydrogen-rich compounds by alloy…
Superconducting gap in covalent bismuth dihydride BiH under extreme conditions
Jianning Guo, Dmitrii V. Semenok, Ivan A. Troyan +17
Hydride superconductors at megabar pressures provide a promising platform for exploring room-temperature superconductivity. However, their superconducting gaps remain largely inacc…
Nevanlinna Analytic Continuation for Migdal-Eliashberg Theory
D. M. Khodachenko, R. Lucrezi, P. N. Ferreira +2
In this work, we present a method to reconstruct real-frequency properties from analytically continued causal Green's functions within the framework of Migdal-Eliashberg (ME) theor…
Probing the superconducting gap structure of ScRuSi via SR and first-principles calculations
K. Panda, A. Bhattacharyya, P. N. Ferreira +6
In this study, we present a thorough investigation into the superconducting state of the ruthenium-based ternary equiatomic compound ScRuSi. Our analysis combines experimental tech…
Ab initio modeling of superconducting alloys
Pedro N. Ferreira, Roman Lucrezi, Ivan Guilhon +4
Designing new, technologically relevant superconductors has long been at the forefront of solid-state physics and chemistry research. However, developing efficient approaches for m…
