Linear estimates for solutions of quadratic equations in free groups
Olga Kharlampovich, Alina Vdovina
We prove that in a free group the length of the value of each variable in a minimal solution of a standard quadratic equation is bounded by for orientable equation and by $12s…
Optimal signal states for quantum detectors
Ognyan Oreshkov, John Calsamiglia, Ramon Munoz-Tapia +1
Quantum detectors provide information about quantum systems by establishing correlations between certain properties of those systems and a set of macroscopically distinct states of…
Searches on star graphs and equivalent oracle problems
Jaehak Lee, Hai-Woong Lee, Mark Hillery
We examine a search on a graph among a number of different kinds of objects (vertices), one of which we want to find. In a standard graph search, all of the vertices are the same,…
Electronic structure via potential functional approximations
Attila Cangi, Donghyung Lee, Peter Elliott +2
The universal functional of Hohenberg-Kohn is given as a coupling-constant integral over the density as a functional of the potential. Conditions are derived under which potential-…
