Photoinduced phase transitions have been intensively studied owing to their promising potential for next-generation devices. Here, the authors develop a novel analysis method: so-called frequency-domain ARPES (FDARPES). They extend well established measurement method of time-domain detect how electrons are interacting with phonons during photoinduced insulator-to-metal transition Ta${}_{2}$NiSe...

The finite temperature phase diagram of a U(1) Higgs-Yukawa model at a finite value of the scalar self coupling λ is investigated by means of a large-Nf calculation and numerical simulations. The phase diagram is similar to the one at zero temperature and shows a ferromagnetic, two symmetric and an antiferromagnetic phase. However, the phase transition lines are shifted to larger values of the ...
