С вопросом разобрался, но может, кому интересно.
Пусть пси-функция описывает нестационарное состояние. Переходим к представлению Гейзенберга, в котором операторы зависят от времени, а новая пси-функция нет. Модуль новой ф-ии тогда тоже не зависит от времени, а первоначальной зависел. Получается, что плотность вероятности зависит от того, каким представлением пользуемся.

А вот здесь я точно не знаю, плотность вероятности чего описывает этот griemiInfamma sad.gif

Получается, что плотность вероятности зависит от того, каким представлением пользуемся.

Плотность вероятности чего именно?
DoubleO
Ну норма самого вектора состояния (т.е. полная вероятность) как была постоянной, так постоянной и осталась. А вот если вы хотите о квадрате модуля волновой функции поговорить, то это квадрат модуля коэффициента разложения по собственным векторам интересующих наблюдаемых. А раз операторы от времени зависят, то и собственные вектора тоже теперь зависят: грубо говоря, в Шредингеровской вектор состояния вращается, а базис стоит на месте, в то время как в Гейзенберговской вектор состояния стоит на месте, а базис вращается. Так что эта вероятность окажется той же самой, зависящей от времени.

Т.к. пси-функция не зависит теперь от времени, то к чему говорить, что норма полстоянна? А вот про полную вероятность не понял. Пси-функция в таком случае определяет вероятность только в начальный момент (ибо не зависит от времени).

Чего-то Вы намудрили. Квадрат модуля пси-функции это ... квадрат модуля (в таком случае постоянен). Никакого отношения к разложению по собственным функциям не имеет.

Так, похоже как всегда нужно воззвать к Духу Формул 198.gif чтобы хотя бы договориться, что кто имеет в виду

Вначале Шредингеровская картина.
Есть состояние |\psi(t)\rangle
Волновая функция - это коэффициенты разложения по собственным векторам оператора координаты psi(x,t)=\langle x|psi(t)\rangle,\hat{x}|x\langle=x|x\langle Оператор координаты у нас сейчас не зависит от времени, как и его собственные вектора
Полная вероятность P=\langle\psi(t)|\psi(t)\rangle=\langle\psi(t)|x\rangle\langle x|\psi(t)\rangle=\int_{-\infty}^{+\infty}|\psi(x,t)|^2dx при унитарной эволюции постоянна и обычно нормируется на единицу
Вероятность поймать частицу в какой-то точке x P(x,t)=|\psi(x,t)|^2=|\langle x|\psi(t)\rangle|^2

Теперь переходим к Гейзенберговской картине
|\psi\rangle=e^{i\hat{H}t}|\psi\rangle,\hat{x}(t)=e^{i\hat{H}t}\hat{x}e^{-i\hat{H}t}
Теперь когда оператор координаты зависит от времени, зависят от времени и его собственные функции. Вы можете проверить, что их можно получить по стандартной формуле |x(t)\rangle=e^{i\hat{H}t}|x\rangle

Ну и я говорю о следующих равенствах

Ну норма самого вектора состояния (т.е. полная вероятность) как была постоянной, так постоянной и осталась

P=\langle \psi(t)|\psi(t)\rangle=\langle \psi|\psi\rangle=const

Э... что я с формульным тегом сделал не так

Просто формулы на этом форуме уже давно не работают.
Насколько я могу расшифровать то, что описывает формулы, Вы описали стационарный случай (рассмотренный в учебниках). Я же спрашивал про нестационарные состояния.

Дух Формул в ярости, ему надо срочно нести богатые дары... 198.gif

Плохо расшифровали. Ни о какой стационарности речи не идет. Обращаю внимание на то, что \hat{H} - это оператор, а не число

Или вы так называете смешанные состояния или неунитарные эволюции какие-нибудь возжелали?

Увы, ничего сказать не могу, т.к. http://www.astronet.ru/db/latex2gif/ показывает ошибку синтаксиса формул.
DoubleO
Я вам отправлю в личку тот же текст, только с долларами вокруг формул (и парой исправленных очепяток) и все будет без ошибок
AndrV
Вы все написали верно.
Проверять формулы можно еще здесь (без долларов): http://expange.ru/useful/tex/
