Production Efficiency of Ultracold Feshbach Molecules in Bosonic and Fermionic Systems [PDF]
We investigate the production efficiency of ultracold molecules in bosonic $^{85}$Rb and fermionic $^{40}$K when the magnetic field is swept across a Feshbach resonance.

Serial-parallel conversion for single photons with heralding signals [PDF]
We present serial-parallel conversion for a heralded single photon source (heralded SPS). We theoretically show that with the heralding signal, the serial-parallel converter can route a stream of n photons to n different spatial modes more efficiently ...

Counterintuitive example on relation between ZT and thermoelectric efficiency [PDF]
The thermoelectric figure of merit ZT, which is defined using electrical conductivity, Seebeck coefficient, thermal conductivity, and absolute temperature T, has been widely used as a simple estimator of the conversion efficiency of a thermoelectric heat

Reinforcing high-density polyethylene by phenolic spheres
Phenolic spheres are synthesized through resorcinol and formaldehyde. The phenolic spheres were blended with HDPE to prepare binary composites. The rheological properties and mechanical properties of the composites were studied.

Exceeding the solar cell Shockley-Queisser limit via thermal up-conversion of low-energy photons [PDF]
Maximum efficiency of ideal single-junction photovoltaic (PV) cells is limited to 33% (for one sun illumination) by intrinsic losses such as band edge thermalization, radiative recombination, and inability to absorb below-bandgap photons.

High efficiency in mode-selective frequency conversion [PDF]
Frequency conversion (FC) is an enabling process in many quantum information protocols. Recently, it has been observed that upconversion efficiencies in single-photon, mode-selective FC are limited to around 80%.In this letter we argue that these limits can be understood as time-ordering corrections (TOCs) that modify the joint conversion amplitude of ...
