Out-of-equilibrium relaxation dynamics of the superconducting order parameter in CsVSb
Avi Shragai, Alexander Won, Jonathan M. DeStefano +4
The application of a time-varying strain field drives a superconducting order parameter out of equilibrium. How the order parameter relaxes back to equilibrium depends both on the…
Symmetry, Sound, and the Quest for Chiral Superconductors
B. J. Ramshaw
The confirmation of a bulk, topological superconductor is a central goal of modern quantum materials research. Despite decades of searching, no confirmed examples yet exist. A prim…
Thermodynamic Discovery of Tetracriticality and Emergent Multicomponent Superconductivity in UTe
Sahas Kamat, Jared Dans, Shanta Saha +4
The candidate topological superconductor UTe exhibits a complex phase diagram with multiple superconducting states, yet the nature of their coexistence has remained a central m…
Vanishing Phase Stiffness and Fluctuation-Dominated Superconductivity in UTe
Sahas Kamat, Jared Dans, Shanta Saha +3
Superconductivity in three dimensions is almost universally governed by Ginzburg-Landau mean field theory, with critical fluctuations typically confined to within a few percent of…
Expert Evaluation of LLM World Models: A High- Superconductivity Case Study
Haoyu Guo, Maria Tikhanovskaya, Paul Raccuglia +20
Large Language Models (LLMs) show great promise as a powerful tool for scientific literature exploration. However, their effectiveness in providing scientifically accurate and comp…
Emergence of Fermi-liquid and BCS physics in overdoped cuprates
B. J. Ramshaw, Steven A. Kivelson
Cuprates are the paradigmatic `unconventional' superconductors: their critical temperature is much higher than can be expected from phonon-mediated pairing; the superconducting gap…
Phonon Hall Viscosity and the Intrinsic Thermal Hall Effect of -RuCl
Avi Shragai, Ezekiel Horsley, Subin Kim +2
The thermal Hall effect has been observed in a wide variety of magnetic insulators, yet its origins remains controversial. While some studies attribute the effect to intrinsic mech…
Giant transverse magnetic fluctuations at the edge of re-entrant superconductivity in UTe
Valeska Zambra, Amit Nathwani, Muhammad Nauman +6
UTe exhibits the remarkable phenomenon of re-entrant superconductivity, whereby the zero-resistance state reappears above 40 tesla after being suppressed with a field of arou…
Multipolar Fermi Surface Deformations in SrRuO Probed by Resistivity and Sound Attenuation: A Window into Electron Viscosity and the Collision Operator
Davis Thuillier, Sayak Ghosh, B. J. Ramshaw +1
Recent developments in electron hydrodynamics have demonstrated the importance of considering the full structure of the electron-electron scattering operator, which encodes a seque…
Hydride superconductivity: here to stay
Gregory S. Boebinger, Andrey V. Chubukov, Ian R. Fisher +12
The field of hydride superconductivity has recently been mired in a controversy that might divert attention from the question of central importance: do hydrides support genuine sup…
Absence of a Bulk Thermodynamic Phase Transition to a Density Wave Phase in UTe2
Florian Theuss, Avi Shragai, Gael Grissonnanche +12
Competing and intertwined orders are ubiquitous in strongly correlated electron systems, such as the charge, spin, and superconducting orders in the high-Tc cuprates. Recent scanni…
and the elastocaloric effect of SrRuO under uniaxial stress: no indications of transition splitting
Fabian Jerzembeck, You-Sheng Li, Grgur Palle +11
There is considerable evidence that the superconductivity of Sr2RuO4 has two components. Among this evidence is a jump in the shear elastic modulus at the critical tempera…
Quantum Fluctuations Suppress the Critical Fields in BaCo(AsO)
Shiva Safari, William Bateman-Hemphill, Asimpunya Mitra +10
Early efforts to realize exotic quantum ground states in frustrated magnets focused on frustration arising from the lattice geometry alone. Attention has shifted to bond-dependent…
Elastocaloric evidence for a multicomponent superconductor stabilized within the nematic state in Ba(FeCo)As
Sayak Ghosh, Matthias S. Ikeda, Anzumaan R. Chakraborty +12
The iron-based high- superconductors exhibit rich phase diagrams with intertwined phases, including magnetism, nematicity and superconductivity. The superconducting in m…

Mark P. Zic, Matthias S. Ikeda, Pierre Massat +6
Adiabatic decompression of para-quadrupolar materials has significant potential as a cryogenic cooling technology. We focus on TmVO, an archetypal material that undergoes a con…
Fragile superconductivity in a Dirac metal
Chris J. Lygouras, Junyi Zhang, Jonah Gautreau +19
Studying superconductivity in Dirac semimetals is an important step in understanding quantum matter with topologically non-trivial order parameters. We report on the properties of…
Resonant Ultrasound Spectroscopy for Irregularly-Shaped Samples and its Application to Uranium Ditelluride
