“…Historically, Khalil, Al Horani, Yousef, and Sababheh were the first who introduce conformable fractional derivatives (CFD) [9]. Some applications of the CFD formalism can be found in the literature [10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26]. In a recent work, authors adopted this formalism to the quantum harmonic oscillator problem [27].…”
