The Ising model in a transverse field is one of the most fundamental models in quantum many-body physics. Despite being around for more than 60 years, we still make new discoveries in it. In our latest work, we show the existence of a dynamical phase […]

What QFT book would you like to read?
If you were to buy an introductory, somewhat informal but not too shallow book on relativistic quantum field theory, which topic would you like to see covered as a bonus chapter beyond the standard treatment (lagrangians and hamiltonians, canonicsl […]

Are there any experts on General Relativity and Einstein-Cartan theory here? I have some technical questions
