Forced to Quit PhD although the hard and proved work I am a first year Ph. D student, and I have been working on a new topic of research.  I worked day and night to prove something new and verified it. I began my Ph. D while my supervisor was on travel, but he returned before I had been here for long.  When he returned, he told me we have to stop and not continue without any reasonable reasons.

After a few months he began treating me poorly---always belittling and underestimating---although I got two grants from a top conference, made videos and podcasts, and constantly received praise for my good work and personality.  

It seems that I have been treated as a competitor, not a collaborator.  Although agreeing with my approaches in private, my supervisor said false words to the committee to take the decision and stop my Ph. D work!

It is not surprising, as there was another former senior Ph. D student who I met on campus, who was not allowed to defend his Ph. D: this same supervisor claimed he was not able to finish his dissertation although he had published in a peer reviewed journal and having citation as well, it was scary and not familiar.

In front of committee, he lied, and said something without proving. I asked if he can make a detailed constructive criticism, but he could not.  All I can say that they are a gang literally, and he said words that show that he is jealous and doesn't want to see me having self confidence in my self. I know no one will believe me, but this is the truth.

Honestly, I am distressed and I'm losing sleep.  I had this dream where there were many people who saw me fail.  All things considered, I don't know whether what happened is good or bad, and I definitely don't know what I should do next!

I would be grateful for your advice and whether there is someone has encountered any similar situation.
You describe a very difficult situation that has only difficult solutions. It seems pointless, even dangerous, to continue with this supervisor and, perhaps, even at this institution. It may be impossible to change the behavior of the supervisor, even if the department puts pressure on him to change. 

However, though difficult and disruptive, you may be able to take the work you have done and use it as a firm basis for application elsewhere. I would normally just suggest changing supervisors at your current place, but it may not be possible and if the current supervisor is truly vindictive, then he might still be able to interfere. 

But if your current and previous work is good, you can find an academic home somewhere. If you decide to move, investigate any future supervisor at least a bit so you don't get in to the same situation again. 

You don't suggest that this could be a case of pure sexism. If it is, then in some places you can make a case for sanction of the professor, of course. Sadly, sexism is too accepted in too many places. 



Let me add that I can't judge your work. It may be that your advisor thinks your work has less value than you do and that is his reason for his behavior. Of course, you have stated that others (reviewers, editors, etc., if that is the meaning of your second paragraph) have given validation to your work by publishing it. 

But even if the professor is correct, it doesn't excuse bad behavior toward a student. If he thinks you are on the wrong path, his job is to guide you to a better path, not to disparage you.
