Symmetry in quantum mechanics (original) (raw)

About DBpedia

Em mecânica quântica, as simetrias descrevem características do espaço-tempo e as partículas que permanecem inalteradas sob alguma transformação, no contexto da mecânica quântica, mecânica quântica relativística (RQM) e teoria quântica de campos, e também com aplicações na e na física da matéria condensada

dbo:abstract التناظرات في ميكانيكا الكم تصف سمات الزمكان والجسيمات التي لم تتغير في بعض التحولات، في سياق ميكانيكا الكم، وميكانيكا الكم النسبية و نظرية الحقل الكمومي، مع تطبيقات الصيغة الرياضية للنموذج القياسي و فيزياء الموادة المكثفة. عموما يمثل التناظر في الفيزياء، والثبات، و قوانين الحفظ، قيودا في صياغة النظريات والنماذج الفيزيائية. في الممارسة العملية، فهي أساليب قوية لحل المشاكل والتنبؤ بما يمكن أن يحدث. في حين أن قوانين الحفظ لا تعطي دائما الإجابة على المشكلة مباشرة، إلا أنها تشكل القيود الصحيحة والخطوات الأولى لحل العديد من المشكلات. توضح هذه المقالة العلاقة بين الشكل الكلاسيكي من التناظرات المستمرة فضلا عن مؤثري الكَمّ، وتربطها بزمرة لاي، والتحولات النسبية في زمرة لورنتز وزمرة بوانكاريه. (ar) Symmetries in quantum mechanics describe features of spacetime and particles which are unchanged under some transformation, in the context of quantum mechanics, relativistic quantum mechanics and quantum field theory, and with applications in the mathematical formulation of the standard model and condensed matter physics. In general, symmetry in physics, invariance, and conservation laws, are fundamentally important constraints for formulating physical theories and models. In practice, they are powerful methods for solving problems and predicting what can happen. While conservation laws do not always give the answer to the problem directly, they form the correct constraints and the first steps to solving a multitude of problems. This article outlines the connection between the classical form of continuous symmetries as well as their quantum operators, and relates them to the Lie groups, and relativistic transformations in the Lorentz group and Poincaré group. (en) Симметрии в квантовой механике — преобразования пространства-времени и частиц, которые оставляют неизменными уравнения квантовой механики. Рассматриваются во многих разделах квантовой механики, которые включают релятивистскую квантовую механику, квантовую теорию поля, стандартную модель и физику конденсированного состояния. В целом, симметрия в физике, законы инвариантности и сохранения являются основополагающими ограничениями для формулирования физических теорий и моделей. На практике это мощные методы решения задач и прогнозирования того, что может случиться. Хотя законы сохранения не всегда дают конечное решение проблемы, но они формируют правильные ограничения и наметки к решению множества задач. В этой статье описывается связь между классической формой непрерывных симметрий, а также их квантовыми операторами, которые связывают их с группами Ли и релятивистскими преобразованиями в группе Лоренца и группе Пуанкаре.
