00925njm 22002777a 4500 dc Luis Aina, Alfredo author 2007-05-30 The use of Rényi entropy as an uncertainty measure alternative to variance leads to the study of states with quantum fluctuations below the levels established by Gaussian states, which are the position-momentum minimum uncertainty states according to variance. We examine the quantum properties of states with exponential wave functions, which combine reduced fluctuations with practical feasibility. 1050-2947 10.1103/PhysRevA.75.052115 https://hdl.handle.net/20.500.14352/51493 http://dx.doi.org/10.1103/PhysRevA.75.052115 http://journals.aps.org/ Quantum properties of exponential states
