Phys. Rev. A 75, 052115 (2007) [6 pages]Quantum properties of exponential statesReceived 31 March 2007; published 30 May 2007 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. © 2007 The American Physical Society URL:
