“…PbS-QDs are one kind of ASMMs, which are not oxidized easily and have high thermal stability in natural conditions [ 94 ]. Under the impact of magnetic field, owing to the transition and energy of spin electrons changed, PbS-QDs will generate energy-level overlap and asymmetric structures, further resulting in the alteration of the magnetic moment, magnetic susceptibility, and refractive index [ 95 , 96 , 97 , 98 ].…”

The magnetic field is a vital physical quantity in nature that is closely related to human production life. Magnetic field sensors (namely magnetometers) have significant application value in scientific research, engineering applications, industrial productions, and so forth. Accompanied by the continuous development of magnetic materials and fiber-sensing technology, fiber sensors based on the Magneto-Refractive Effect (MRE) not only take advantage in compact structure, superior performance, and strong environmental adaptability but also further meet the requirement of the quasi-distributed/distributed magnetic field sensing; they manifest potential and great application value in space detection, marine environmental monitoring, etc. Consequently, the present and prevalent Magneto-Refractive Magnetic Field Fiber Sensors (MR-MFSs) are briefly summarized by this paper, proceeding from the perspective of physicochemical properties; design methods, basic performance and properties are introduced systematically as well. Furthermore, this paper also summarizes key fabrication techniques and future development trends of MR-MFSs, expecting to provide ideas and technical references for staff engaging in relevant research.

“…This results indicate the Rashba spin-orbit coupling, confined potential, electronphonon coupling, magnetic field and phonon wave vector promote a variation of the first excited state energy. In paper [78] calculated the energies of the ground and the first excited states of a free polaron and that of a polaron bound to a Coulomb impurity in a quantum dot with harmonic confinement in the presence of Rashba spin-orbit interaction. Splitting here also investigate the combined effect of Rashba and polaronic interactions in the presence of an external magnetic field using the Rayleigh-Schrödinger perturbation theory.…”

In this work I review of the theoretical and experimental issue related to the Rashba Spin-Orbit interaction in semiconductor nanostructures. The Rashba spin-orbit interaction has been a promising candidate for controlling the spin of electrons in the field of semiconductor spintronics. In this work, I focus study of the electrons spin and holes in isolated semiconductor quantum dots and rings in the presence of magnetic fields. Spin-dependent thermodynamic properties with strong spin-orbit coupling inside their band structure in systems are investigated in this work. Additionally, specific heat and magnetization in two dimensional, one-dimensional quantum ring and dot nanostructures with Spin Orbit Interaction are discussed.

“…Over recent years, applying the unitary transformation of Lee-Low-Pines type (UTLLPT) [44] and variational method of Pekar type (VMPT), [45,46] we have investigated some thermodynamic, electromagnetic and optical properties of QDs. [29][30][31][47][48][49][50][51][52][53][54][55][56][57] Al-though, in recent years, the Rashba effect [58][59][60] and magnetic field [61][62][63] influence of polaron in parabolic quantum dots have been studied, the temporal spatial distribution of the probability density (PD) and the influences of the RSOI and the temperature on the PD and the oscillating period (OP) of a parabolic QD (PQD) have not been accounted yet. In the present study, we mainly investigate the PD and OP in a PQD under the RSOI and temperature influences using the UTLLPT and VMPT.…”

We study the property of magnetopolaron in a parabolic quantum dot under the Rashba spin–orbit interaction (RSOI) by adopting an unitary transformation of Lee–Low–Pines type and the variational method of Pekar type with and without considering the temperature. The temporal spatial distribution of the probability density and the relationships of the oscillating period with the RSOI constant, confinement constant, electron–phonon coupling strength, phonon wave vector and temperature are discussed. The results show that the probability density of the magnetopolaron in the superposition of the ground and first excited state takes periodic oscillation (T 0/period) in the presence or absence of temperature. Because of the RSOI, the oscillating period is divided into different branches. Also, the results indicate that the oscillating period increases (decreases) when the RSOI constant, electron-phonon coupling strength and phonon wave vector (the confinement constant) increase in a proper temperature, and the temperature plays a significant role in determining the properties of the polaron.
