WebOct 2, 2024 · Spectral characterization is a fundamental step in the development of useful quantum technology platforms. Here, we study an ensemble of interacting qubits coupled … WebIn previous work, we have demonstrated that quantum diffractive collisions between a thermal background gas and a cold, trapped sensor gas follow a universal law for certain collision partners. Specifically, we found that the sensor gas loss rate from a trap of depth U follows a universal function P (U/U d ) of the trap depth scaled by a diffractive energy …

WebWe derive the phase diagram of a scalar two-level boson model by studying the equilibrium and stability properties of its energy surface. The plane of control parameters is enlarged with respect to previous studies. We then analyze the time evolution of wave packets centered around the ground state at various quantum phase transition boundary lines.
