"Favorite Reads" Reading List
This is a list of some papers that I've especially enjoyed reading, or found especially helpful. Maybe some others will too!
Far from complete, but will continue adding favorites to it as inspired.
By year:

Noether, 1918.
Invariante Variationsprobleme.
We all know the First Theorem (global symmetries) in this paper. But what about the Second (gauge symmetries)? 
Gabor, 1946.
Theory of communication. Part 1: The analysis of information.
The bandwidth theorem. What is the information content of signals and their spectra? And in Part 2, the analysis of human hearing. 
Shannon, 1948.
A mathematical theory of communication.
Just a classic. 
DeWitt, 1975.
Quantum field theory in curved spacetime.
A review with a point of view. You can't get a more concise description of the basics than 1.1 here. And DeWitt is such a great writer. 
Ashtekar and Magnon, 1975.
Quantum fields in curved spacetimes.
What are positive/negative frequency modes in curved spacetime, and why are they so important? 
Candelas, 1980.
Vacuum polarization in Schwarzschild spacetime.
Concise reference giving renormalized stress tensors in the Boulware, HartleHawking, and Unruh states. 
Carlitz and Willey, 1987.
Reflections on moving mirrors
and
Lifetime of a black hole.
Nice insights into both the Hawking effect and moving mirror paradigm, with some interesting consequences in the second part. 
Padmanabhan and Singh, 1987.
Response of an accelerated detector coupled to the stressenergy tensor.
Do accelerated particle detectors click because of Rindler particles? No. 
Doran et al, 1993.
Lie groups as spin groups.
Every Lie algebra is isomorphic to a bivector Lie algebra. That is, all Lie Algebras are described within Clifford algebra. (This is more awesome than it sounds.) 
Cerf and Adami, 1998.
Quantum Information Theory of Entanglement and Measurement.
Came for the discussion of information in quantum measurement. Stayed for the Venn diagrams. 
Modi et al, 2010.
Unified View of Quantum and Classical Correlations.
Concise explanation distinguishing classical correlations, quantum correlations, and entanglement. 
Ashtekar, 2020.
Black Hole Evaporation: A Perspective from Loop Quantum Gravity.
A modern bigpicture persepective on BH evaporation.
