A waveguide cavity resonator source of squeezing
M. Stefszky, R. Ricken, C. Eigner +3
We present the generation of continuous-wave optical squeezing from a titanium-indiffused lithium niobate waveguide resonator. We directly measure 2.9\pm 0.1 dB of single-mode sque…
Integrated optical source of polarization entangled photons at 1310 nm

We report the realization of a new polarization entangled photon-pair source based on a titanium-indiffused waveguide integrated on periodically poled lithium niobate pumped by a C…
Shocks in non-loaded bead chains with impurities
E. Hascoet, H. Herrmann
We numerically investigate the problem of the propagation of a shock in an horizontal non-loaded granular chain with a bead interaction force exponent varying from unity to large v…
Modified Two-Photon Interference Achieved by the Manipulation of Entanglement
P. R. Sharapova, K. H. Luo, H. Herrmann +3
In this theoretical study we demonstrate that entangled states are able to significantly extend the functionality of Hong-Ou-Mandel (HOM) interferometers. By generating a coherent…
Breeding and Solitary Wave Behavior of Dunes
O. Duran, V. Schwaemmle, H. Herrmann
Beautiful dune patterns can be found in deserts and along coasts due to the instability of a plain sheet of sand under the action of the wind. Barchan dunes are highly mobile aeoli…
High-quality polarization entanglement state preparation and manipulation in standard telecommunication channels
F. Kaiser, A. Issautier, L. A. Ngah +5
We report a novel and simple approach for generating near-perfect quality polarization entanglement in a fully guided-wave fashion. Both deterministic pair separation into two adja…
A high-power waveguide resonator second harmonic device with external conversion efficiency up to 75%
M. Stefszky, R. Ricken, C. Eigner +3
We report on a highly efficient waveguide resonator device for the production of 775 nm light using a titanium indiffused LiNbO3waveguide resonator. When scanning the resonance the…
Quantum optical coherence: From linear to nonlinear interferometers
K. -H. Luo, M. Santandrea, M. Stefszky +6
Interferometers provide a highly sensitive means to investigate and exploit the coherence properties of light in metrology applications. However, interferometers come in various fo…
Crossover from directed percolation to compact directed percolation
J. F. F. Mendes, R. Dickman, H. Herrmann
We study critical spreading in a surface-modified directed percolation model in which the left- and right-most sites have different occupation probabilities than in the bulk. As we…
Experiments conducted in the burning plasma regime with inertial fusion implosions
J. S. Ross, J. E. Ralph, A. B. Zylstra +149
An experimental program is currently underway at the National Ignition Facility (NIF) to compress deuterium and tritium (DT) fuel to densities and temperatures sufficient to achiev…
Improving SPDC single-photon sources via extended heralding and feed-forward control
M. Massaro, E. Meyer-Scott, N. Montaut +2
Evolving photonic quantum technologies and applications require higher and higher rates of single photon generation. In parallel, it is required that these generated photons are ke…
Models for Free Granular Surfaces
R. Mulet, H. Herrmann
We introduce two sets of continuum equations to describe granular flow on a free surface and study their properties. The equations derived from a microscopic picture that includes…
A consistent view of the samarium hexaboride terminations to resolve the nature of its surface states
H. Herrmann, P. Hlawenka, K. Siemensmeyer +11
The research effort prompted by the prediction that SmB could be the first topological Kondo insulator has produced a wealth of new results, though not all of these seem compat…
Polarization entangled photon-pair source based on a type-II PPLN waveguide emitting at a telecom wavelength

Single-photon entanglement is a simple form of entanglement that exists between two spatial modes sharing a single photon. Despite its elementary form, it provides a resource as us…
A Model of Barchan Dunes Including Lateral Shear Stress
V. Schwaemmle, H. Herrmann
Barchan dunes are found where sand availability is low and wind direction quite constant. The two dimensional shear stress of the wind field and the sand movement by saltation and…
