Searching for a Lost PhD Thesis on Black Holes

In summary: The first is a paper on how the area of the black hole should increase in proportion to the entropy in the box, which is a quantum phenomena. The second is a paper on how the generalized second law of thermodynamics applies to black hole physics.

TL;DR Summary
See title
The paper is reasonably old and was written as a phd thesis by (I believe) a man from china. It was basically the first paper on the subject and in it he effectively (from what I understand) dropped particles into a black hole, counting the information added, and saw that the black hole changed in size such that the information contained by the particles measured in bits of order plank length was proportional to the change in surface area of the black hole. I want to try to read this paper, but cannot remember the name of the author nor the title. Google searching, skimming the holographic principle wikipedia page, information theory page all provided no results.

If anyone knows the paper I'm referring to and would either link it, drop the name, or at least the authors name, I would appreciate it.

Nobody has an actual black hole in their lab.

I suspect you are referring to experiments where sound waves in a fluid are used to create a state which has a sort of "horizon" that has some similarities with a black hole horizon:

As Peter points out, nobody has a black hole in the lab. So you know neither the author, nor the title, nor the journal, nor the date, nor exactly what the paper is about.

It will be tough to find.

Here are related papers about dropping a box into a black hole. The area of the black hole should increase in proportion to the entropy in the box. It's a quantum phenomenon, so the area can be thought of as being in Planck units.

But from the description the OP is looking for some sort of experimental paper.

Yes I should have specified I suppose... It is a theoretical paper. From what I understand it was the first paper that suggested the holographic principal (which it wasn't called at the time).

I've been on a physics history kick lately. Trying to look at some of the first papers on various topics. This one has been on my mind and I just can't remember what it is. I am fairly certain this specific paper was written by a Chinese man as his PhD thesis.

I know that no one has a black hole in their lab... The premise of the paper is (theoretically) drop particles into a black hole, count the quantum information added to the black hole, calculate the changes in the black hole, discover that the information added is proportional to the change in surface are. I know I'm asking for a lot, I remember just stumbling on it back when I wasn't very interested in it, which is unfortunate. I can't remember where. I might have to rewatch some Susskind lectures, it might have been brought up in one of them or maybe not. I wish I knew. It's been bugging me for a while.

The classic theoretical papers on this are Bekenstein's; @atyy linked to two of them in post #4.
