“…Sistem partikel tunggal 1D dengan mekanika gelombang Schrodinger telah banyak diimplementasikan sebagai working substance [2,3,6] hingga kajian dimensi geometri ruang Hilbert sistem [12] . Kajian mesin Carnot kuantum dengan Hamiltonian relativistik Dirac menunjukkan hasil yang berkorespondensi dengan sistem klasiknya [13,14], hasil yang sama juga diperoleh untuk dua partikel relativistik [15] dengan dua skenario konfigurasi sistem dengan model analogi.…”

The heat engine, as a device for converting heat energy into work, enters the era of miniaturization until microscopic size. Thus a quantum review for thermodynamic concepts are urgent to be done. A quantum theory has been constructed for adiabatic and iso-volume processes over a 1D piston system with 2 symmetry particles. The method used is an analogical model of a thermodynamic system with a quantum mechanical system modified by the first law of thermodynamic implementation for a quantum system. Analogical model involves the analogical system of a piston being a 1D box with one of the free moving walls and the analogical process that implements the first law of thermodynamics for a quantum system. The results obtained are the configurations of the state of the system, the energy representations during isovolume and adiabatic processes and the equation of the system which is equivalent to the ideal gas equation. With the resulting of these adiabatic and the isovolume processes of quantum systems, a cycle process of quantum Otto 2 symmetry particles and the descriptions of efficiency can be evaluated.

“…Then, this classical system is substituted by a quantum system. The quantum system applied can be either an infinite potential well [3][4][5][6][7][8][9][10][11] or a harmonic oscillator [12][13][14] to produce an engine efficiency that exceeds the classical version.…”

A theoretical quantum Brayton engine research has been carried out using a potential box system to increase its thermal efficiency. The method applied in this research is a classical thermodynamics system model in the form of a piston tube containing a monatomic ideal gas analogous to a quantum model in the form of a potential box containing one particle. The efficiency formulation of the quantum Brayton engine obtained from this study is following the classical version. However, the efficiency value obtained on a quantum Brayton engine is higher when compared to its classic. It happens because the value of the Laplace constant owned by the Brayton quantum version is 3, while the classic version is 5/3.

“…Quantum physics offers a quantum system as a substitute for the classical system to improve the thermal efficiency of a classical system engine. Quantum systems used are potential wells [4,5,6,7,8,9,10,11,12,13], quantum harmonic oscillators [14,15], and others.…”

Lenoir engine based on the quantum system has been studied theoretically to increase the thermal efficiency of the ideal gas. The quantum system used is a single particle (as a working fluid instead of gas in a piston tube) in a one-dimensional infinite potential well with a wall that is free to move. The analogy of the appropriate variables between classical and quantum systems makes the three processes for the classical Lenoir engine applicable to the quantum system. The thermal efficiency of the quantum Lenoir engine is found to have the same formulation as the classical one. The higher heat capacity ratio in the quantum system increases the thermal efficiency of the quantum Lenoir engine by 56.29% over the classical version at the same compression ratio of 4.41.
