Believed to be typos in Desai’s QM Text
Posted by peeterjoot on November 19, 2010
Vatche says that the root cause of what I’ve identified as a typo is in some cases incorrect, and that he’s going through the text carefully himself too.
\item Page 7. Text before (1.43). instead of used.
\item Page 19. Equation (1.122). s omitted after first equality.
\item Page 40. Text before (2.137). Reference to equation (2.133) should be (2.135)
\item Page 53. Is the “Also show that” here correct? I get a different answer.
\item Page 61. Equation (3.51). missing.
\item Page 66. Equation (3.92). should be .
\item Page 66. Equation (3.93). on wrong side of
\item Page 81. Equation (4.52). Should be in the exponent.
\item Page 82. Equation (4.67). in the denominator of the normalization should be .
\item Page 83. Equation (4.74). A normalized wave function isn’t required for the discussion, but if that was intended, a factor is missing.
\item Page 86. Equation (4.99). Extra brace in the exponent.
\item Page 87. Equation (4.106). Extra brace in the exponent.
\item Page 89. Equation (4.129), (4.130). should be
\item Page 93. Equation (4.169). conjugation missing for . is missing prime on the index.
\item Page 95. Second line of text. Language choice? “We now implement”. perhaps utilize would be better?
\item Page 95. Text before (4.193). is in bold.
\item Page 96. Text before (4.196). is in bold.
\item Page 97. (4.205). is in bold.
\item Page 97. (4.207-209). , and s aren’t in bold like
\item Page 101. (4.239-240). The approach here is unclear. FIXME: incorporate lecture notes from class that did this using braket notation.
\item Page 102. (4.248-249). Commas missing to separate , and in the kets.
\item Page 113. (5.86). One isn’t in bold.
\item Page 114. (5.100). is in bold.
\item Page 115. Text before (5.106). in bold.
\item Page 118. Switch of notation in problem 5 for ensemble averages. used instead of .
\item Page 120. in bold. not in bold.
\item Page 123. (6.26). factor missing on RHS.
\item Page 124. Text before (6.37). You say canonical momenta , but call these mechanical momenta on prev page.
\item Page 125. (6.41). Some s are in bold.
\item Page 126. (6.49). There’s no mention that is constant, leaving it unclear how the gauge condition and how the curl of reproduces . This would also help clarify how you are able to write .
\item Page 128. (6.65). should be .
\item Page 129. (6.75). should be .
