With the increased use of ionizing radiations across a spectrum of applications, the quest for identifying low-cost thermoluminescence (TL) materials to be used for radiation dosimetry is of vital importance. Therefore, identification and confirmation of natural materials suitable for radiation dosimetry is an active area of research. Such potential materials must have features like rigidity, insolubility, and chemical inertness etc. besides having additional dosimetric characteristics. One such promising low-cost material can be a limestone having vast deposits in Pakistan. So far, the TL and dosimetric characterization of pellets fabricated with Pakistani limestone and irradiated with X-rays has not been previously reported. All the studied literature has reported powdered form of limestone. The present study reports pelletized limestone and its intercomparison with *** quarried crystalline samples of limestone were hand crushed, sieved and compressed to fabricate pellets of size comparable to standard TLD chips. TL response, kinetic parameters, dose linearity, batch homogeneity, individual sensitivity correction factor (i.e., elemental correction coefficient ECC), lowest detectable dose limit (LDDL), coefficient of variation (COV), energy dependency (for X-ray energy range from 50 kV to 6 MV), and response fading (for a month) were determined and compared with TLD-100. For TL analysis, pellets were irradiated to 250 kV X-rays with a dose of 8 Gy. The pellets exhibited complex TL glow curve showing four peaks (P1, P2, P3 and P4) with a peak temperature of around P1 (90–110°C), P2 (130–170°C), P3 (240–280°C) and P4 (320–350°C) respectively. A dose linearity (with 250 kV X-rays) for 1–10 Gy, was observed while comparing with TLD-100. The pellets showed a linearity while TLD-100 showed supra-linearity in the studied dose range. Tm-Tstop method was applied initially for TL analysis to identify the overlapping peaks of the glow curve followed by Computerized gl

Hybrid quantum-classical algorithms have been suggested to control the quantum entanglement of many-body systems in noisy intermediate-scale quantum technology, and yet their applicability is limited by the numbers of qubits and quantum operations. Here, we propose a mean-operator theory which overcomes limitations by combining the advantages of hybrid algorithms and standard mean-field theory. We demonstrate that an introduction of a mean operator prepares an entangled target many-body state with a significantly reduced number of quantum operations. We also show that a class of mean operators is expressed as time-evolution operators, which indicates that our theory is directly applicable to quantum simulations with Rydberg atoms and trapped ions.
