Quench dynamics and relaxation of a spin coupled to interacting leads
Helena Bragança, Moallison F. Cavalcante, R. G. Pereira +1
We study a quantum quench in which a magnetic impurity is suddenly coupled to Hubbard chains, whose low-energy physics is described by Tomonaga-Luttinger liquid theory. Using the t…

Controlling valley splitting and Polarization of dark- and bi-excitons in monolayer WS by a tilted magnetic field
Fanyao Qu, Helena Bragança, Railson Vasconcelos +3
We developed a comprehensive theoretical framework focusing on many-body effects of exciton species in monolayer WS, including bright and dark excitons, and intra- and inter-va…
