DOI // MD5 Resolver

This is the endpoint of the DOI resolver of the Institute for Theoretical Physics III of the University of Stuttgart.

Its main purpose is to serve original research papers to students of our classes, in particular old manuscripts that are hard to come by and might not even have a DOI (like many of the foundational papers of relativity by Albert Einstein). We use it in our lecture notes and exercise assignments to provide direct download links for references.

If you enter a DOI below, the following can happen:

• The document exists in our database:
• If the paper is freely available (open access or in the public domain), the PDF file opens directly.
  Example: https://doi.itp3.info/10.1103/physrevlett.45.494
• If the paper is copyright protected, you are asked to enter an access key before you can download the PDF file.
  This key is made available to students of our classes.
  Example: https://doi.itp3.info/10.1103/PhysRevB.83.035107
• The document does not exists in our database. Then you are redirected via doi.org to the journal's webpage.
  Example: https://doi.itp3.info/10.1103/PhysRevLett.134.084101

There are some papers in our database that do not have a DOI.
These are identified by the MD5 hash of their PDF file (which can also be submitted below).
Example: https://doi.itp3.info/650aebc80e4c295a6c3d40cd0df42889
