Ion velocity
While ionic mobilities -as defined- show marked differences, the actual ion velocities offer alternative insights. The average instantaneous thermal velocity of ions in water is quite high, on the order of 102 m/s (estimated from…

Quantum frequency resampling | npj Quantum Information
The encoding
In this section, we discuss the operating principles of our quantum resampling algorithms for a signal encoded in the probabilities of a multiqubit state. We propose two complementary protocols, one for downsampling, i.e., for…

Current scaling of the magnetoresistance peaks in the microwave radiation induced magnetoresistance oscillations
GaAs/AlGaAs single heterojunctions with electron density \(n=2.6 \times 10^{11} \,\,{\rm cm}^{-2}\) and mobility \(\mu = 8 \times 10^{6} \,\,{\rm cm}^{-2}/Vs\) were patterned by photolithography into Hall bar type devices, including triple…

Unveiling the role of dual grading in device optimization of HTL-free Sb2(S, Se)3 solar cells
The main purpose of employing suitable ETL and HTL is to accelerate the transition of electrons and holes from the absorber to the FC and back contact (BC), respectively, while inhibiting the movement of electrons and holes to the BC and FC as…

Altermagnetism and strain induced altermagnetic transition in Cairo pentagonal monolayer
Cairo pentagonal lattice structure and model Hamiltonian
We consider a Cairo pentagonal lattice with space group P4/mbm, shown in Fig. 1a. Due to the presence of non-magnetic sites, the opposite spin sublattices can not be mapped to each other by…
