Authors: Bello, M.; Platero, G.; Gonzalez-Tudela, A. Journal: PRX QUANTUM Publication date: 2022/03/07 DOI: 10.1103/PRXQuantum.3.010336 Abstract: Waveguide QED has emerged as a powerful analog quantum simulator due to the possibility of mediating versatile spin-spin interactions with tunable sign, range, and even dimerization. Yet, despite their potential, the many-body phases emerging from these systems have only [...]

Authors: Mousavi, S., V; Miret-Artes, S. Journal: EUROPEAN PHYSICAL JOURNAL PLUS Publication date: 2022/01/19 DOI: 10.1140/epjp/s13360-022-02367-6 Abstract: Some unexplored decoherence aspects within the Caldeira-Leggett master equation are analyzed and discussed. The decoherence process is controlled by the two environment parameters, the relaxation rate or friction and the temperature, leading to a gradual transition from the [...]
