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…
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…
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…
Strong Magneto-Elastic Coupling in MnX (X = Ge, Sn)
Florian Theuss, Sayak Ghosh, Taishi Chen +3
We measure the full elastic tensors of MnGe and MnSn as a function of temperature through their respective antiferromagnetic phase transitions. Large discontinuities in the…
Elastocaloric determination of the phase diagram of SrRuO
You-Sheng Li, Markus Garst, Jörg Schmalian +11
One of the main developments in unconventional superconductivity in the past two decades has been the discovery that most unconventional superconductors form phase diagrams that al…
Strong Increase in Ultrasound Attenuation Below T in SrRuO: Possible Evidence for Domains
Sayak Ghosh, Thomas G. Kiely, Arkady Shekhter +5
Recent experiments suggest that the superconducting order parameter of SrRuO has two components. A two-component order parameter has multiple degrees of freedom in the supe…
Thermodynamic Evidence for a Two-Component Superconducting Order Parameter in SrRuO
Sayak Ghosh, Arkady Shekhter, F. Jerzembeck +6
SrRuO has stood as the leading candidate for a spin-triplet superconductor for 26 years. Recent NMR experiments have cast doubt on this candidacy, however, and it is diffic…
A key role of correlation effects in the Lifshitz transition in SrRuO
Mark E. Barber, Frank Lechermann, Sergey V. Streltsov +8
Uniaxial pressure applied along an Ru-Ru bond direction induces an elliptical distortion of the largest Fermi surface of SrRuO, eventually causing a Fermi surface topologic…
One-Component Order Parameter in URuSi Uncovered by Resonant Ultrasound Spectroscopy and Machine Learning
Sayak Ghosh, Michael Matty, Ryan Baumbach +6
The unusual correlated state that emerges in URuSi below T = 17.5 K is known as "hidden order" because even basic characteristics of the order parameter, such as its…
Spatially modulated heavy-fermion superconductivity in CeIrIn5
Maja D. Bachmann, G. M. Ferguson, Florian Theuss +20
The ability to spatially modulate the electronic properties of solids has led to landmark discoveries in condensed matter physics as well as new electronic applications. Although c…
