Understanding Circumflex Operators: Get Help Now

[regory]

Hi
I have a problem for understanding the difference between an circumflex operator and non-circumflex operador.
I'd appreciate your help

I have a problem for understanding the difference between an circumflex operator and non-circumflex operador.

Where are you seeing these terms used? Can you give a reference?

Today my physics teacher said that the circumflex operator (for example Ĥ) is different to the operator H because Ĥ is normalized. I have always used ^ for denote any operator and I don't find information about this difference.

Did you ask your teacher what they meant by "normalized", or what difference "normalizing" an operator makes?

I don't find information about this difference.

Where have you looked?

Did you ask your teacher what they meant by "normalized", or what difference "normalizing" an operator makes?

Or, did your teacher give explicit examples of a non-normalized operator $H$ and the corresponding normalized operator $\hat{H}$?

I think we'd need a source, where these distinctions are made. It's not a common notation. Usually one uses a hat above a symbol to indicate that one deals with an operator rather than a (real or complex) number in quantum mechanics. I also don't know, what "normalization of an operator" means.
