Phononic soft mode behavior and a strong electronic background across the structural phase transition in the excitonic insulator Ta_{2}NiSe_{5}
Ta_{2}NiSe_{5} became one of the most investigated candidate materials for hosting an excitonic insulator ground state. Many studies describe the corresponding phase transition as a condensation of excitons breaking a continuous symmetry. This view got challenged recently pointing out the importance...
