Selection from heaps, row-sorted matrices and X+Y using soft heaps
Abstract: We use soft heaps to obtain simpler optimal algorithms for selecting the k-th smallest item, and the set of k smallest items, from a heap-ordered tree, from a collection of sorted lists, an...

Finite-component system phase transitions in and out of equilibrium
Abstract: Contrary to the long-held belief that phase transitions occur only in the thermodynamic limit of infinite number of constituents, we have recently discovered that finite-component systems o...

Towards an Optical Frequency Standard based on 176Lu+
Abstract: In essence, the accuracy and performance of an atomic clock ultimately depends on various systematic shifts in the narrow-linewidth transition in an isolated atomic system. Lutetium ion pos...
