Two-spin resonances in double quantum dots with a constant spin-orbit coupling (SOC) can be induced by an ac field which periodically modulates the energy detuning. But a large ac field amplitude may unintentionally trigger an ac modulation in the SOC, which in turn can alter the frequency of the resonances and the form of the current peaks. Here, we demonstrate that depending on the applied magnetic field and the double quantum dot parameters a weak time dependence in the SOC can have a completely different effect on the resonant peaks; in particular, it can enhance the peaks, but it can also completely suppress them.

In this work, to control the content of dichroic complexes in film polarizers based on polyvinyl alcohol, a luminescent technique is proposed that allows us to estimate: the ratio of molecular and paired iodine centers in H-type polarizers at T = 4.2 K; of dichroic complexes caused by molecular and aggregated forms of the dye in L-type polarizers at T = 300 K. The use of this technique will make it possible in the future to establish the dependence of the properties of polarizers on the structure of dichroic complexes, not only in H-type or L-type film polarizers but also in mixed (H + L)-type polarizers, to create polarizers of various spectral ranges.

Single Photon Sources (SPSs) play a pivotal role in fields such as quantum communication and quantum cryptography by generating information in a secure manner. However, realizing the ideal emission of single photons with high efficiency is still a theoretical model. This leads to the presence of multiphoton components in SPSs, which could potentially compromise security. This study focuses on enhancing the purity of a class of sources by characterizing their photon number distribution and mitigating the impact of the multiphoton components. We propose the use of Photon Number Resolving Detectors (PNRD) as a technique to exclude multiphoton contributions, particularly in sources like Spontaneous Parametric Down Conversion sources, where emitted photons can be represented as Two-Mode Squeezed Vacuum states. By analyzing the second-order cross-correlation function, g2(0), using either PNRD or Single Photon Detectors, we can quantify the reduction in multiphoton contributions.

The requirements and details of designing a measuring cell and low-back-action deeply-cooled amplifier for quantum measurements at 10 mK are discussed. This equipment is a part of a microwave single-photon counter based on a superconducting flux qubit. The high-electron mobility transistors (HEMTs) in the amplifier operate in unsaturated microcurrent regime and dissipate only 1 μW of dc power per transistor. Simulated amplifier gain is 15 dB at 450 MHz with a high-impedance (≈ 5 kΩ) signal source and standard 50-Ω output.

In thin film technology, substrate materials happen to be one of the deposition parameters that determine the physical properties of films. Hence, soda-lime glass and quartz continue to be the widely utilized substrate materials because of their high-frequency performance, price, and surface quality. For certain applications, various substrate materials that provide an acceptable compromise for the work at hand are required. Soda-lime glass and quartz have been chosen as the substrates for the tin and chromium thin films that will be produced via thermal evaporation in a vacuum. A comparative study on the electrical properties of chromium films was made in the light of Fuchs–Sondheimer and Mayadas–Shatzkes theories. Numerous physical properties, including resistivity of infinitely thick film, sticking coefficient, conduction electron mean free, etc., may be determined from resistivity-thickness data.

Low-temperature anomalies of dielectric permittivity of Sn2P2S6 crystals were investigated. It is shown that these phenomena have a relaxation character and the observed anomalies could be related to the small hole polarons dynamics with donor-acceptor compensation processes in lattice with tin and sulfur vacancies. To confirm it, we measured the dielectric properties of tin-enriched and sulfur-enriched crystals. It is shown that deviation from stoichiometry leads to a significant change in the low-temperature anomalies of dielectric losses.

Thermomagnetoelectric effect for the dielectric hydrodynamic system is considered. It is established that in a liquid, which is placed in a magnetic field, the temperature gradient can cause a convective mass flow, which leads to the appearance of an electric field in the surrounding space. The distribution of electric potential for various geometric implementations is calculated. A comparison of the obtained effect for normal and superfluid 4He is performed.

This work introduces a cryovacuum apparatus used to investigate substances under near-space conditions. This device allows one to study the refractive index, infrared spectra, and density of substances that are condensed from the vapor phase onto a cooled substrate at temperatures ranging from 11 K to 300 K. Concurrently, the ultimate pressure of 0.1 nTorr can be obtained in the vacuum chamber. The introduced setup utilizes FTIR spectroscopy with a spectral measurement range of 400–7800 cm−1 and laser interference needed to determine the important physical and optical parameters. Several experiments allow us to stress that the data acquired using this apparatus are quite similar to those obtained by other researchers. Because of the non-directional deposition of substances from the vapor phase, the ice formed closely resembles the ice formed in space. This makes the introduced setup particularly useful. It is possible to use the presented cryovacuum apparatus to interpret data acquired in the course of astrophysical observations, allowing a researcher to determine the properties of space objects.

It has been established that molybdenum has a dispersing effect on the grain structure of the copper matrix, which consists of the blocking effect of monoatomic molybdenum adsorption layers formed on the surface of growing copper grains during the condensation of a two-component vapor. The structure of Cu-0.3 at. % Mo condensates demonstrates increased thermal stability, retaining the size of the original grain upon annealing up to 800 °C.
