Impact of dynamic Jahn-Teller effect on magnetic excitations, lattice vibration, and thermal conductivity in UxTh1-xO2 system
Saqeeb Adnan, Zilong Hua, Puspa Upreti +11
Vibrational and magnetic properties of single-crystal uranium-thorium dioxide (UxTh1-xO2) with a full range of 0<x<1 is investigated. Thorium dioxide is a diamagnet whose thermal p…

Optical pulse induced ultrafast antiferrodistortive transition in SrTiO3
Saqeeb Adnan, Amey Khanolkar, Shuxiang Zhou +2
The ultrafast dynamics of the antiferrodistortive (AFD) phase transition in perovskite SrTiO3 is monitored via time-domain Brillouin scattering. Using femtosecond optical pulses, w…

Thermal conductivity suppression in uranium-doped thorium dioxide due to phonon resonant scattering
Zilong Hua, Saqeeb Adnan, Amey R. Khanolkar +7
In this work, the thermal transport properties of thorium dioxide (ThO, thoria) with low levels of substitutional uranium (U) doping are explored. We observe strong indications…
