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…
The rectilinear Steiner tree problem with given topology and length restrictions
Jens Maßberg
We consider the problem of embedding the Steiner points of a Steiner tree with given topology into the rectilinear plane. Thereby, the length of the path between a distinguished te…
Quantum Speed Limit and Optimal Control of Many-Boson Dynamics
Ioannis Brouzos, Alexej I. Streltsov, Antonio Negretti +4
We extend the concept of quantum speed limit -- the minimal time needed to perform a driven evolution -- to complex interacting many-body systems. We investigate a prototypical man…
A positive tensor network approach for simulating open quantum many-body systems
A. H. Werner, D. Jaschke, P. Silvi +4
Open many-body quantum systems play an important role in quantum optics and condensed-matter physics, and capture phenomena like transport, interplay between Hamiltonian and incohe…
A spatial-correlation analysis of the cubic 3-torus topology based on the Planck 2013 data
R. Aurich
Spatial correlations of the cubic 3-torus topology are analysed using the Planck 2013 data. The spatial-correlation method for detecting multiply connected spaces is based on the f…
Enhancing light-harvesting power with coherent vibrational interactions: a quantum heat engine picture
Nathan Killoran, Susana F. Huelga, Martin B. Plenio
Recent evidence suggests that quantum effects may have functional importance in biological light-harvesting systems. Along with delocalized electronic excitations, it is now suspec…
Locating-dominating sets in twin-free graphs
Florent Foucaud, Michael A. Henning, Christian Löwenstein +1
A locating-dominating set of a graph is a dominating set of with the additional property that every two distinct vertices outside have distinct neighbors in ; th…
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…
Structural phase transitions and topological defects in ion Coulomb crystals
Heather L. Partner, Ramil Nigmatullin, Tobias Burgermeister +7
We use laser-cooled ion Coulomb crystals in the well-controlled environment of a harmonic radiofrequency ion trap to investigate phase transitions and defect formation. Topological…
Maximal Regularity: Positive Counterexamples on UMD-Banach Lattices and Exact Intervals for the Negative Solution of the Extrapolation Problem
Stephan Fackler
Using methods from Banach space theory, we prove two new structural results on maximal regularity. The first says that there exist positive analytic semigroups on UMD-Banach lattic…
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…
Ultrasensitive Magnetometer Using a Single Atom
I. Baumgart, J. -M. Cai, A. Retzker +2
Precision sensing, and in particular high precision magnetometry, is a central goal of research into quantum technologies. For magnetometers, often trade-offs exist between sensiti…
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…
A generalisation of the form method for accretive forms and operators
A. F. M. ter Elst, Manfred Sauter, Hendrik Vogt
The form method as popularised by Lions and Kato is a successful device to associate m-sectorial operators with suitable elliptic or sectorial forms. McIntosh generalised the form…
Generalizations of a cotangent sum associated to the Estermann zeta function
Helmut Maier, Michael Th. Rassias
Cotangent sums are associated to the zeros of the Estermann zeta function. They have also proven to be of importance in the Nyman-Beurling criterion for the Riemann Hypothesis. The…

Vincenzo Tamma, Simon Laibacher
We provide a compact full description of multiboson correlation measurements of arbitrary order N in passive linear interferometers with arbitrary input single-photon pure states.…
Universal Set of Gates for Microwave Dressed-State Quantum Computing
Gatis Mikelsons, Itsik Cohen, Alex Retzker +1
We propose a set of techniques that enable universal quantum computing to be carried out using dressed states. This applies in particular to the effort of realising quantum computa…
