Abstract

Telah dilakukan penelitian tentang penentuan energi keadaan dasar osilator kuantum anharmonik menggunakan metode kuantum difusi Monte Carlo. Pada penelitian ini simulasi energi keadaan dasar osilator kuantum anharmonik dibuat dengan menggunakan suku anharmonik λx3, dengan memvariasikan suku pengganggu λ. Hasil yang diperoleh dari simulasi ini yaitu, energi keadaan dasar osilator kuantum anharmonik menggunakan metode kuantum difusi Monte Carlo memiliki selisih terbesar sekitar 1,1% dengan teori gangguan dan selisih terbesar sekitar 0,7% dengan energi keadaan dasar osilator kuantum anharmonik menggunakan metode random walk.
