If you want research-level physics papers about topics high school students can understand, your best bet might be to look to the past. Older papers are great fun to read, but with their archaic language and notation they're not always the most efficient way to learn. One famous exception is Einstein's 1905 classic On the Electrodynamics of Moving Bodies. ...

It seems to me Fermi's 1949 paper On the origin of the cosmic radiation (pdf copy link) is fairly accessible, requiring basic E&M and conservation of energy & momentum. The paper was written as a proposal for a mechanism to accelerate cosmic rays from thermal velocities to relativistic ones. The mechanism he proposes (based on Alfven waves) ...

I'll give it a try: Jesse L. Silverberg, Matthew Bierbaum, James P. Sethna, and Itai Cohen, Phys. Rev. Lett. 110, 228701 (2013): "Collective Motion of Humans in Mosh and Circle Pits at Heavy Metal Concerts". (I got the idea from a Sixty Symbols video.) http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.110.228701 It's not written by someone famous ...

As noted in P. Weinberger's revisit of Louis de Broglie's 1924 doctoral thesis: De Broglie's contribution in the Philosophical Magazine from 1924 is fascinating from many standpoints: for its moderate use of mathematics, the close connection to Einstein's special theory of relativity, and of course for the proposal of matter waves. We revisit ...

I'm going to be perverse and suggest Blas Cabrera's "First Results from a Superconductive Detector for Moving Magnetic Monopoles" (Phys. Rev. Lett. 48, 1378 (1982).) Cabrera isn't a household name, of course, but this does have some advantages as a teaching paper: First, the experiment is dead simple to explain to students who know about EMFs and ...

I think that your teacher (?) asked you about thermal de Broglie wavelength, where $$\lambda_T \propto\frac{1}{\sqrt{T}}.$$ You get this expression when you express the momentum in $\lambda=h/p$ in in terms of kinetic energy and the kinetic energy itself in terms of the energy due to temperature. (The derivation is also in the wikipedia article...) Indeed, ...

Some of the mathematical aspects of the Liouville operator can be found in the second book by Reed and Simon, in section X.14 (it is not a comprehensive account, but it gives the basic ideas and proofs). In the notes at the end of chapter X, in the part dedicated to section X.14, there is also a quite extensive bibliography that may be useful.

All these links are accessible at a non-mathematical level, and they are by recognized scientists (with the exception of the first link). (1) To start, see the "Simple English Wikipedia", which explains what the Higgs effect is, and the reason for the Higgs effect: http://simple.wikipedia.org/wiki/Higgs_field. (2) The difference between the Higgs boson and ...

(i) Roger Shawyer Shawyer's output seems to be mostly available on emdrive.com. Among the theoretical explanations he provides there are A Note on the Principles of EmDrive force measurement Principle of Operation Theory paper None of these appear to be peer-reviewed. (ii) NWPU group Applying Method of Reference 2 to Effectively Calculating ...
