Narrow-Band Terahertz Pulse Generation in Lithium Niobate Crystal Using Phase Mask J. Contemp. Phys. (IF 0.6) Pub Date : 2023-12-01
Abstract Below, we theoretically study the generation of narrowband terahertz (THz) radiation by optical rectification in an artificial periodically poled lithium niobate (LN) crystal with a wide aperture. The latter is formed by placing a multi-slit phase mask in front of a conventional (single-domain) LN crystal. It is shown that the bandwidth of THz generation can be varied over a wide range by

Pair-Interacting Heavy Holes Gas in a Strongly Prolate Ellipsoidal Quantum Dot: Thermodynamic Properties J. Contemp. Phys. (IF 0.6) Pub Date : 2023-12-01
Abstract A somewhat partial pair-interacting gas of heavy holes localized in a highly elongated ellipsoidal Ge/Si quantum dot has been studied in the adiabatic approximation. The interparticle interaction potential is considered within the one-dimensional Moshinsky atom model when the interaction depends on the square of the distance between particles. Within the framework of the Boltzmann approximation
