Non-destructive selective probing of phononic excitations in a cold Bose gas using impurities
D. Hangleiter, M. T. Mitchison, T. H. Johnson +3
We introduce a detector that selectively probes the phononic excitations of a cold Bose gas. The detector is composed of a single impurity atom confined by a double-well potential,…
Square ice in graphene nanocapillaries
G. Algara-Siller, O. Lehtinen, F. C. Wang +5
Adsorbed layers of water are ubiquitously present at surfaces and fill in microscopic pores, playing a central role in many phenomena in such diverse fields as materials science, g…
Optimizing for an arbitrary perfect entangler. II. Application
Michael H. Goerz, Giulia Gualdi, Daniel M. Reich +7
The difficulty of an optimization task in quantum information science depends on the proper mathematical expression of the physical target. Here we demonstrate the power of optimiz…
Atomistic mechanism of carbon nanotube cutting catalyzed by nickel under the electron beam
Irina V. Lebedeva, Thomas W. Chamberlain, Andrey M. Popov +5
The cutting of single-walled carbon nanotubes by an 80 keV electron beam catalyzed by nickel clusters is imaged in situ using aberration-corrected high-resolution transmission elec…
The rate of growth of moments of certain cotangent sums
Helmut Maier, Michael Th. Rassias
We consider cotangent sums associated to the zeros of the Estermann zeta function considered by the authors in their previous paper [5]. We settle a question on the rate of growth…
Scalable reconstruction of unitary processes and Hamiltonians
M. Holzäpfel, T. Baumgratz, M. Cramer +1
Based on recently introduced efficient quantum state tomography schemes, we propose a scalable method for the tomography of unitary processes and the reconstruction of one-dimensio…
