An interesting discussion on the journal club of CMP: about the discovery of chiral Majorana zero modes in QAHI by K. Wang and S.C. Zhang

After the publication of this paper, about the signature of chiral Majorana zero modes in the quantum anomalous Hall insulator, Prof. Jason Alicea wrote a commentary on Journal Club for Condensed Matter Physics.

However, Prof. Beenakker wrote another commentary to oppose this experiment, in which he cited two theoretical articles showing that the e2/2h does not need the presence of chiral Majorana modes. This argument is actually just recently confirmed by a recent experiment.

It is always fun to read the discussions between physicists. Science evolves through them.

What are the benefits of getting a Ph.D.? A perspective from a Ph.D. physicist now working in the chip industry

After working as a postdoc for four years, I recently left academia and enjoy my new life working in the industry. As my current role does not require a Ph.D. degree, I sometimes feel regretful about not starting my industry career earlier. Looking back on my decision of getting a Ph.D. in physics, I used to be passionate about doing scientific research and imagined myself working as a physicist in a research institute like my former employer LLNL. I decided to leave academia because I was tired of the uncertainties in both research itself and personal finance as a postdoc, especially after my son was born.  After watching an inspiring interview with Prof. George A. Constantinides  posted by Shilicon (老石) on YouTube, I feel resonated with one of the sentences by George. He said that getting a Ph.D. is a rare chance that you can have a certain block of time in your life where you can focus on a specific research field and dig deeply into it without worrying too much about other...

L. D. Landau

Today, I came across Landau's Wikipedia page and the biography of Landau written by Dr. Lifshitz in Volume 1 of Course of Theoretical Physics "Mechanics". His diverse knowledge in theoretical physics and research attitude really impress me a lot. His name indeed appears in many physics textbooks, but what astonished me the most is that he learned about the latest research results from seminars instead of reading papers, and he always by himself worked out the novel research results that interested him instead of following the authors' reasonings.
