$T_c$ and the elastocaloric effect of Sr$_2$RuO$_4$ under $langle 110 rangle$ uniaxial stress: no indications of transition splitting

Kavli Affiliate: Brad J. Ramshaw | First 5 Authors: Fabian Jerzembeck, You-Sheng Li, Grgur Palle, Zhenhai Hu, Mehdi Biderang | Summary: There is considerable evidence that the superconductivity of Sr2RuO4 has two components. Among this evidence is a jump in the shear elastic modulus $c_{66}$ at the critical temperature $T_c$, observed in ultrasound measurements. Such […]

Arresting Quantum Chaos Dynamically in Transmon Arrays

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Rohit Mukherjee, Haoyu Guo, Keiran Lewellen, Debanjan Chowdhury, | Summary: Ergodic quantum many-body systems evolving under unitary time dynamics typically lose memory of their initial state via information scrambling. Here we consider a paradigmatic translationally invariant many-body Hamiltonian of interacting bosons — a Josephson junction array in […]
