Hello everyone, I'm a physics student and have got a matter that has been bothering me, therefore I would like to hear your opinion and perhaps your experiences. So now I have been doing my master thesis and I plan to find a PhD position after graduation. The problem is I want to take a topic for my PhD research which is different from my current master thesis topic. They are actually not far apart though, they are still under the same branch of physics. The thing is, it's not that I suddenly wanted to change research subject, when I decided to undertake my current research topic I thought that it will have some relevance with the topic of my desired future research in PhD. But after a while working in my current research, I realized that it doesn't have a very strong connection with the one I aimed for in the PhD. So what I want to hear from you is that is it common for a student to change research topics between the one in master and that in PhD? Will the difference in the research area become part of the judgement process by the admission committee when I apply for a PhD later in the future? In addition in case you have similar experience as mine during your graduate time, was it though in your PhD research when your previous research subjects were different? In my case I guess the problem would be only in the areas of research skills, because I have taken courses strongly related to the subject I aim for in PhD but I will surely lack experimental skill by the time I start my PhD.
