I think 'Ender's Game' is popular among students. The physics - related military strategies in the book are very interesting to students who like to think about strategic problems. 'Snow Crash' is also popular as it has a cool concept of virtual reality which is related to modern technology and physics. 'The Martian' is another popular one as it shows how practical physics knowledge can be used in extreme situations, and students can learn a lot from the protagonist's problem - solving methods using physics.
