Controlling the transport of an ion: Classical and quantum mechanical solutions
H. A. Fürst, M. H. Goerz, U. G. Poschinger +6
We investigate the performance of different control techniques for ion transport in state-of-the-art segmented miniaturized ion traps. We employ numerical optimization of classical…
Information Maps: A Practical Approach to Position Dependent Parameterization
Benjamin wilking, Daniel Meissner, Stephan Reuter +1
In this contribution a practical approach to determine and store position dependent parameters is presented. These parameters can be obtained, among others, using experimental resu…
Noise Studies of Driven Geometric Phase Gates with Trapped Ions
A. Lemmer, A. Bermudez, M. B. Plenio
We present a study of the performance of the trapped-ion driven geometric phase gates introduced in [New J. Phys. 15, 083001 (2013)] when realized in a stimulated Raman transition.…
Longest Paths in Circular Arc Graphs
Felix Joos
As observed by Rautenbach and Sereni (arXiv:1302.5503) there is a gap in the proof of the theorem of Balister et al. (Longest paths in circular arc graphs, Combin. Probab. Comput.,…
Forests and Trees among Gallai Graphs
Felix Joos, Van Bang Le, Dieter Rautenbach
The Gallai graph of a graph has the edges of as its vertices and two distinct vertices and of are adjacent in if the edges and of a…
Deformation induced changes in surface properties of polymers investigated by scanning force microscopy
Sabine Hild, Armin Rosa, Othmar Marti
In this study the possibility of combining commercial Scanning Force Microscopes (SFM) with stretching devices for the investigation of microscopic surface changes during stepwise…
Induced Matchings in Subcubic Graphs
Felix Joos, Dieter Rautenbach, Thomas Sasse
We prove that a cubic graph with edges has an induced matching with at least edges. Our result generalizes a result for planar graphs due to Kang, Mnich, and Müller (Indu…
The Cycle Spectrum of Claw-free Hamiltonian Graphs
Jonas Eckert, Felix Joos, Dieter Rautenbach
If is a claw-free hamiltonian graph of order and maximum degree with , then has cycles of at least $\min\left\{ n,\left\lceil\frac{3}{2}Δ\right\rceil\righ…
Random Subgraphs in Sparse Graphs
Felix Joos
We investigate the threshold probability for connectivity of sparse graphs under weak assumptions. As a corollary this completely solve the problem for Cartesian powers of arbitrar…
Independence and Matching Number in Graphs with Maximum Degree 4
Felix Joos
We prove that and for every triangle-free graph with maximum degree at most , where is the independenc…
Local Strong Solutions for the Non-Linear Thermoelastic Plate Equation on Rectangular Domains in -Spaces
Stephan Fackler, Tobias Nau
We consider the non-linear thermoelastic plate equation in rectangular domains . More precisely, is considered to be given as the Cartesian product of whole or half spaces a…
M-Functionals of Multivariate Scatter
Lutz Duembgen, Markus Pauly, Thomas Schweizer
This survey provides a self-contained account of -estimation of multivariate scatter. In particular, we present new proofs for existence of the underlying -functionals and di…
Extracting entanglement from identical particles
N. Killoran, M. Cramer, M. B. Plenio
Identical particles and entanglement are both fundamental components of quantum mechanics. However, when identical particles are condensed in a single spatial mode, the standard no…
Tensor networks for Lattice Gauge Theories and Atomic Quantum Simulation
E. Rico, T. Pichler, M. Dalmonte +2
We show that gauge invariant quantum link models, Abelian and non-Abelian, can be exactly described in terms of tensor networks states. Quantum link models represent an ideal bridg…
Transport enhancement from incoherent coupling between one-dimensional quantum conductors
J. J. Mendoza-Arenas, M. T. Mitchison, S. R. Clark +3
We study the non-equilibrium transport properties of a highly anisotropic two-dimensional lattice of spin-1/2 particles governed by a Heisenberg XXZ Hamiltonian. The anisotropy of…
A Characterization of Mixed Unit Interval Graphs
Felix Joos
We give a complete characterization of mixed unit interval graphs, the intersection graphs of closed, open, and half-open unit intervals of the real line. This is a proper supercla…
Maximal Non-Exchangeability in Dimension d
Michael Harder, Ulrich Stadtmüller
We give the maximal distance between a copula and itself when the argument is permuted for arbitrary dimension, generalizing a result for dimension two by Nelsen (2007), Klement an…
Inverse counting statistics for stochastic and open quantum systems: the characteristic polynomial approach
M. Bruderer, L. D. Contreras-Pulido, M. Thaller +3
We consider stochastic and open quantum systems with a finite number of states, where a stochastic transition between two specific states is monitored by a detector. The long-time…
Competition between memory-keeping and memory-erasing decoherence channels
Tony J. G. Apollaro, Salvatore Lorenzo, Carlo Di Franco +2
We study the competing effects of simultaneous Markovian and non-Markovian decoherence mechanisms acting on a single spin. We show the existence of a threshold in the relative stre…
Maximal Regularity for Non-Autonomous Second Order Cauchy Problems
Dominik Dier, El Maati Ouhabaz
We consider non-autonomous wave equations \[ \left\{ \begin{aligned} \&\ddot u(t) + \B(t)\dot u(t) + \A(t)u(t) = f(t) \quad t\text{-a.e.}\\ \&u(0)=u_0,\, \dot u(0) = u_1. \end{alig…
