Materials that can switch between low and high thermal conductivity states enable on-demand management of temperature and heat flow, which will advance the application of solid-state refrigeration, energy conversion, and thermal circuits. Here, we report a large thermal conductivity on/off ratio of ∼1.49, accompanied b...
We present the first search for the doubly Cabibbo-suppressed decays $D^0\to K^+\pi^-\eta^\prime$ and $D^+\to K^+\pi^0\eta^\prime$ using an $e^+e^-$ collision data sample corresponding to an integrated luminosity of 20.3 fb$^{-1}$, collected at a center-of-mass energy of 3.773 GeV with the Beijing Spectrometer III (BES...

Using 7.33 fb$^{-1}$ of $e^+e^-$ annihilation data recorded with the BESIII detector at center-of-mass energies from 4.128 to 4.226 GeV, we report the first observation and dynamical study of the semileptonic decay $D^+_s\to f_{0}(980) \mu^+\nu_\mu$. The absolute branching fraction of $D^+_s\to f_{0}(980) \mu^+\nu_\mu$...

Using $2712.4 \pm 14.3$ million $\psi(3686)$ events collected with the BESIII detector, the $\Lambda\bar{\Lambda}$ system produced in $\psi(3686)$ radiative decays is studied. A model-independent partial wave analysis reveals a significant threshold enhancement structure dominated by the $^1S_0$ and $^3P_0$ partial wav...

Based on $4.5\, \mathrm{fb}^{-1}$ of $e^+e^-$ collision data collected with the BESIII detector at the BEPCII collider at center-of-mass energies between $4.600\,\mathrm{GeV}$ and $4.699\,\mathrm{GeV}$, the first search for the Cabbibo-suppressed semileptonic decay $\Lambda_c^+\to p\pi^-e^+\nu_e$ is performed. The bran...

Using $e^+e^-$ collision data samples collected with the BESIII detector at the BEPCII at center-of-mass energies between 3.510 and 4.951 GeV corresponding to an integrated luminosity of 44.55 fb$^{-1}$, the Born cross sections of the processes $e^+e^- \to K_S^0 \bar{\Xi}^0 \Lambda/\Sigma^0+\text{c.c.}$ are measured wi...

Based on a data sample of 10 billion $J/\psi$ events collected with the BESIII detector operating at the BEPCII collider, the Dalitz decay $\Sigma^0 \rightarrow \Lambda e^+e^-$ is studied experimentally for the first time. The $\Sigma^0$ hyperons are produced through the process $J/\psi \rightarrow \Sigma^0\bar{\Sigma}...
