Investigating the EM performance of building materials for mid-band 5G in urban built environment: an exploratory study by Ng, Sean Jake Peng

“…This comprehensive study encompasses various factors, including the choice of aggregate types (FAC and fine sand), different levels of Fe2O3 inclusions (2 wt% and 4 wt%), and channel frequencies within the 3300 to 3800 MHz frequency band (divided into five 100 MHz channels). Prior to the statistical analysis, |S21| parameters were measured using an S-band waveguide experiment setup. …”

Nonreciprocal phenomena in superconductivity by Davydova, Marharyta

“…The first example that we discuss is nonreciprocal superconductivity, which occurs upon simultaneous breaking of inversion and time-reversal symmetries. Nonreciprocal superconductors describe certain classes of unconventional superconductors that include certain kinds of mixed-pairing and finite-momentum ones. …”

Ultra-fast all-optical switching based on nanoantenna coupled to monolayer TMDs by Song, Qige

“…They are currently one of the frontiers of research. The band gaps of few-layer TMDs are in the visible and near-infrared regions, and their excitons have considerable binding energies at room temperature, high resonant oscillator strengths, and valley-selective circular dichroism due to spatial inversion symmetry breaking, which make TMDs particularly attractive. …”

Investigation of solar cell carrier lifetime using photoconductance lifetime measurements by Sng, Joseph Ding Wen

“…The hole-selective contact is achieved by inducing a strong band bending in Si, arising from the high work function (≳ 5.5 eV) of the TMO, to result in a strong upward bending at the n-type Si, leading to carrier inversion at the Si surface. …”

Quantum spin Hall effect and topological phase transition in InNxBiySb1−x−y/InSb quantum wells by Song, Zhigang, Bose, Sumanta, Fan, Weijun, Zhang, Dao Hua, Zhang, Yan Yang, Li, Shu Shen

“…We confirm that such transition are topological phase transitions between a traditional insulator and a TI exhibiting QSH effect—by demonstrating the topologically protected edge-states using the bandstructure, edge-localized distribution of the wavefunctions and edge-state spin-momentum locking phenomenon, presence of non-zero conductance in spite of the Fermi energy lying in the bandgap window, crossover points of Landau levels in the zero-mode indicating topological band inversion in the absence of any magnetic field and presence of large Rashba spin-splitting, which is essential for spin-manipulation in TIs.…”

Theoretical studies and model calculations of femtosecond stimulated Raman spectroscopy by Qiu, Xueqiong

“…It's showed that eight terms contribute to the FSRS, and we grouped them in four groups, which correspond to four nonlinear processes - stimulated Raman scattering (SRS(I) and SRS(II)) and inverse Raman scattering (IRS(I) and IRS(II)). The SRS(I) contributes to the Stokes band, IRS(I) contributes to anti-Stokes band of FSRS spectra, while the SRS(II) and IRS(II) form the baseline of FSRS spectra. …”
