On moments-preserving cosine families and semigroups in
Adam Bobrowski, Delio Mugnolo
We use the newly developed Kelvin's method of images \cite{kosinusy,kelvin} to show existence of a unique cosine family generated by a restriction of the Laplace operator in $C[0,1…
A Robust Measure of Cosmic Structure beyond the Power-Spectrum: Cosmic Filaments and the Temperature of Dark Matter
Danail Obreschkow, Chris Power, Martin Bruderer +1
We discover that the mass of dark matter particles mDM is imprinted in phase-correlations of the cosmic density field more significantly than in the 2-point correlation. In particu…
Entanglement generation in a system of two atomic quantum dots coupled to a pool of interacting bosons
Anna Posazhennikova, Reinhard Birmuske, Martin Bruderer +1
We discuss entanglement generation in a closed system of one or two atomic quantum dots (qubits) coupled via Raman transitions to a pool of cold interacting bosons. The system exhi…
Room temperature Rydberg Single Photon Source
M. M. Müller, A. Kölle, R. Löw +3
We present an optimal protocol to implement a room temperature Rydberg single photon source within an experimental setup based on micro cells filled with thermal vapor. The optimiz…
Room temperature entanglement between distant single spins in diamond
Florian Dolde, Ingmar Jakobi, Boris Naydenov +7
Entanglement is the central yet fleeting phenomena of quantum physics. Once being considered a peculiar counter-intuitive property of quantum theory it has developed into the most…
Berry phase in atom optics
Polina V. Mironova, Maxim A. Efremov, Wolfgang P. Schleich
We consider the scattering of an atom by a sequence of two near-resonant standing light waves each formed by two running waves with slightly different wave vectors. Due to opposite…
Exploiting structured environments for efficient energy transfer: The phonon antenna mechanism
M. del Rey, A. W. Chin, S. F. Huelga +1
A non-trivial interplay between quantum coherence and dissipative environment-driven dynamics is becoming increasingly recognised as key for efficient energy transport in photosynt…
Symmetry Breaking and Topological Defect Formation in Ion Coulomb Crystals
Karsten Pyka, Jonas Keller, Heather L. Partner +9
Symmetry breaking phase transitions play an important role in nature. When a system traverses such a transition at a finite rate, its causally disconnected regions choose the new b…
Ambient Nanoscale Sensing with Single Spins Using Quantum Decoherence
L. P. McGuinness, L. T. Hall, A. Stacey +11
Magnetic resonance detection is one of the most important tools used in life-sciences today. However, as the technique detects the magnetization of large ensembles of spins it is f…
Estimation of classical parameters via continuous probing of complementary quantum observables
Antonio Negretti, Klaus Mølmer
We discuss how continuous probing of a quantum system allows estimation of unknown classical parameters embodied in the Hamiltonian of the system. We generalize the stochastic mast…
Human-Centric Process-Aware Information Systems (HC-PAIS)
Sonja Kabicher-Fuchs, Stefanie Rinderle-Ma, Jan Recker +8
Process-Aware Information Systems (PAIS) support organizations in managing and automating their processes. A full automation of processes is in particular industries, such as servi…
Quantum optical reconstruction scheme using weak values
Joachim Fischbach, Matthias Freyberger
A quantum state contains the maximal amount of information available for a given quantum system. In this paper we use weak-value expressions to reconstruct quantum states of contin…
The emergence of atomic semifluxons in optical Josephson junctions
M. Grupp, W. P. Schleich, E. Goldobin +3
We propose to create pairs of semifluxons starting from a flat-phase state in long, optical 0-pi-0 Josephson junctions formed with internal electronic states of atomic Bose-Einstei…
Atom lens without chromatic aberrations
Maxim A. Efremov, Polina V. Mironova, Wolfgang P. Schleich
We propose a lens for atoms with reduced chromatic aberrations and calculate its focal length and spot size. In our scheme a two-level atom interacts with a near-resonant standing…
Enhancing non-classicality in mechanical systems
Jie Li, Simon Groeblacher, Mauro Paternostro
We study the effects of post-selection measurements on both the non-classicality of the state of a mechanical oscillator and the entanglement between two mechanical systems that ar…
Computing -functions and semistable reduction of superelliptic curves
Irene I. Bouw, Stefan Wewers
We give an explicit description of the stable reduction of superelliptic curves of the form at primes $\p$ whose residue characteristic is prime to the exponent . We…
Matrix Product State Representation without explicit local Hilbert Space Truncation with Applications to the Sub-Ohmic Spin-Boson Model
Max F. Frenzel, Martin B. Plenio
We present an alternative to the conventional matrix product state representation, which allows us to avoid the explicit local Hilbert space truncation many numerical methods emplo…
Limiting distribution for the maximal standardized increment of a random walk
Zakhar Kabluchko, Yizao Wang
Let be independent identically distributed random variables with , . Suppose that for all…
Quasi maximum likelihood estimation for strongly mixing state space models and multivariate Lévy-driven CARMA processes
Eckhard Schlemm, Robert Stelzer
We consider quasi maximum likelihood (QML) estimation for general non-Gaussian discrete-ime linear state space models and equidistantly observed multivariate Lévy-driven continuous…
Factorization of numbers with Gauss sums: II. Suggestions for implementations with chirped laser pulses
W. Merkel, S. Wölk, W. P. Schleich +3
We propose three implementations of the Gauss sum factorization schemes discussed in part I of this series: (i) a two-photon transition in a multi-level ladder system induced by a…
Factorization of numbers with Gauss sums: I. Mathematical background
S. Wölk, W. Merkel, W. P. Schleich +2
We use the periodicity properties of generalized Gauss sums to factor numbers. Moreover, we derive rules for finding the factors and illustrate this factorization scheme for variou…
Factorization of numbers with truncated Gauss sums at rational arguments
S. Wölk, C. Feiler, W. P. Schleich
Factorization of numbers with the help of Gauss sums relies on an intimate relationship between the maxima of these functions and the factors. Indeed, when we restrict ourselves to…
Matroid and Tutte-connectivity in infinite graphs
Henning Bruhn
We relate matroid connectivity to Tutte-connectivity in an infinite graph. Moreover, we show that the two cycle matroids, the finite-cycle matroid and the cycle matroid, in which a…
The Kalton-Lancien Theorem Revisited: Maximal Regularity does not extrapolate
Stephan Fackler
We give a new more explicit proof of a result by Kalton & Lancien stating that on each Banach space with an unconditional basis not isomorphic to a Hilbert space there exists a gen…
