Abstract: the quantum time of arrival (TOA) problem requires the statistics of measured arrival times given only the initial state of a particle. Following the standard framework of quantum theory, the problem translates into finding an appropriate quantum image of the classical arrival time, usually in operator form. In this paper, we consider the problem anew within the phase space formulation of quantum mechanics. The resulting quantum image is a real-valued and time-reversal symmetric function in formal series of ℏ2 with the classical arrival time as the leading term. It is obtained directly from the Moyal bracket relation with the system Hamiltonian and is hence interpreted as a Moyal deformation of the classical TOA. We investigate its properties and discuss how it bypasses the known obstructions to quantization by showing the isomorphism between and the rigged Hilbert space TOA operator constructed in Pablico and Galapon {Eur. Phys. J. Plus 138, 153 (2023)}, which always satisfy the time-energy canonical commutation relation for arbitrary analytic potentials. We then examine TOA problems for a free particle and a quartic oscillator potential as examples.

Abstract: It was shown in Phys. Rev. Lett. 108, 170402 (2012) that quantum tunneling is instantaneous using a time-of-arrival (TOA) operator constructed by Weyl quantization of the classical TOA. However, there are infinitely many possible quantum images of the classical TOA, leaving it unclear if one is uniquely preferred over the others. This raises the question on whether instantaneous tunneling time is simply an artifact of the chosen ordering rule. Here, we demonstrate that tunneling time vanishes for all possible quantum images of the classical arrival time, irrespective of the ordering rule between the position and momentum observables. The result still holds for TOA-operators that are constructed independent of canonical quantization, while still imposing the correct algebra defined by the time-energy canonical commutation relation.

Abstract: There are significant limitations in the current study on CT+STEM addressing the gaps noted in the existing literature. The study is driven by the lack of research on underrepresented students in college STEM courses, the inclusion of CT in STEM education at the entry level, and the insufficiency of teacher training programs that concentrate on integrating computational thinking into STEM classrooms. It aims to fill the knowledge gap about how CTs' professional experience influences their attitudes and practices. The study acknowledges the necessity of empirical research to explore the balance between the widespread use of critical thinking and the distinct characteristics of scientific representations, a significant obstacle in educational planning. The research utilizes bibliometric analysis to cover the period from 1978 to 2023, showing a steady yearly growth rate of 7.22% in the CT+STEM sector. The collection consists of 241 documents from 127 scholarly sources, highlighting collaboration trends and worldwide relationships in CT+STEM research. The study highlights important publications, authors, affiliations, and highly cited papers while also recognizing potential bias and the quantitative character of the investigation. The study has important implications for education, industry, and problem-solving in the digital era. The article suggests further research to investigate qualitative aspects, methodologies, and teaching strategies to enhance the development and influence of CT+STEM in the evolving field of education and technology.
