"Nobel Laureate Steven Weinberg demonstrates exceptional insight in this fully updated concise introduction to modern quantum mechanics for graduate students."

"This book was inspired by the general observation that the great theories of modern physics are based on simple and transparent underlying mathematical structures – a fact not usually emphasized in standard physics textbooks – which makes it easy for mathematicians to understand their basic features. It is a textbook on quantum theory intended for advanced undergraduate or graduate students: mathematics students interested in modern physics, and physics students who are interested in the mathematical background of physics and are dissatisfied with the level of rigor in standard physics courses. More generally, it offers a valuable resource for all mathematicians interested in modern physics, and all physicists looking for a higher degree of mathematical precision with regard to the basic concepts in their field."

"Operator evolusi waktu merupakan pembawa dinamika dalam mekanika kuantum. Keadaan stasioner suatu partikel mengakibatkan bahwa fungsi gelombangnya dapat dipisahkan dengan separasi variabel. Secara analitik faktor dinamika seringkali dihilangkan karena keterbatasan kemampuan penghitungan. Dengan bantuan komputer posisi dan dinamika partikel dapat digambarkan secara utuh melaui penyelesaian persamaan schrodinger gayut waktu. Untuk itu perlu suatu skema numerik untuk operator evolusi waktu. Dalam paper ini akan diajukan skema numerik yang mungkin untuk memodelkan operator evolusi waktu diantaranya model Baker Champbel Hausdorf, dan model Richardson."

"This second edition of an extremely well-received book presents more than 250 nonrelativistic quantum mechanics problems of varying difficulty with the aim of providing students didactic material of proven value, allowing them to test their comprehension and mastery of each subject. The coverage is extremely broad, from themes related to the crisis of classical physics through achievements within the framework of modern atomic physics to lively debated, intriguing aspects relating to, for example, the EPR paradox, the Aharonov-Bohm effect, and quantum teleportation. Compared with the first edition, a variety of improvements have been made and additional topics of interest included, especially focusing on elementary potential scattering. The problems themselves range from standard and straightforward ones to those that are complex but can be considered essential because they address questions of outstanding importance or aspects typically overlooked in primers. The book offers students both an excellent tool for independent learning and a ready-reference guide they can return to later in their careers."
