What are the units of a wave function

Click For Summary
The discussion centers on the units of a wave function in quantum mechanics, with the initial intuition suggesting it is unitless. However, since the magnitude squared of the wave function represents a probability density, it must have units of 1 over some power of length, specifically 1/L^(n/2) where n is the dimension. Participants confirm that there is no error in this reasoning. A referenced article is provided for further reading on the topic. The conversation reinforces the understanding of wave function units in relation to probability density.

My intuition is that it would be unitless. But if it's magnitude squared is a probability density, then its units would have to be 1 over some power of length. Specifically 1/L^(n/2) where n is the dimension. Where's the error in my thought? Thanks

No error. You're right.
 
Thanks guys. That's a nice article also.
 
Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
