$T_c$ 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 […]

Electric leakage suppression of phase-transforming ferroelectrics with donor impurities

Kavli Affiliate: Xian Chen | First 5 Authors: Chenbo Zhang, Xiaotong Peng, Bo Liu, Kai Zhang, Xian Chen | Summary: Phase-transforming ferroelectric materials are widely used in energy harvesting and conversion devices. However, the functionality of these devices is significantly impeded by electrical leakage at high temperatures. In this study, we fundamentally study the mechanism […]

Measurements of the branching fractions of $Ξ_{c}^{0}toΞ^{0}π^{0}$, $Ξ_{c}^{0}toΞ^{0}η$, and $Ξ_{c}^{0}toΞ^{0}η^{prime}$ and asymmetry parameter of $Ξ_{c}^{0}toΞ^{0}π^{0}$

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We present a study of $Xi_{c}^{0}toXi^{0}pi^{0}$, $Xi_{c}^{0}toXi^{0}eta$, and $Xi_{c}^{0}toXi^{0}eta^{prime}$ decays using the Belle and Belle~II data samples, which have integrated luminosities of 980~$mathrm{fb}^{-1}$ and 426~$mathrm{fb}^{-1}$, respectively. We measure the following relative branching fractions $${cal B}(Xi_{c}^{0}toXi^{0}pi^{0})/{cal B}(Xi_{c}^{0}toXi^{-}pi^{+}) […]
