Data from: Direct generation of spatially entangled qudits using quantum nonlinear holography - variances
<p>Nonlinear holography shapes the amplitude and phase of generated new harmonics using nonlinear processes. Classical nonlinear holography influenced many fields in optics, from information storage, de-multiplexing of spatial information and all-optical control of accelerating beams. Here, we extend the concept of nonlinear holography to the quantum regime. We directly shape the spatial quantum correlations of entangled photon pairs in two-dimensional patterned nonlinear photonic crystals using spontaneous parametric down conversion, without any pump shaping. The generated signal-idler pair obeys a parity conservation law that is governed by the nonlinear crystal. Furthermore, the quantum states exhibit quantum correlations and violate the Clauser-Horne-Shimony-Holt inequality, thus enabling entanglement-based quantum key distribution. Our demonstration paves the way for controllable on-chip quantum optics schemes utilizing the high-dimensional spatial degree of freedom.</p>
Equilibrated Kremer-Grest polymer melts of M=1000 linear chains with Z=200 entanglements for varying chain stiffness
<p>Kremer-Grest model polymer melts of highly entangled linear chains. Each melt has approximately 1000 chains of Z=200 entanglements each. Systems have been generated for integer and half-integer stiffness kappa=-2.0 to 6.0. System sizes range from 25M to 2M beads.</p> <p>For details regarding the equilibration process and the Kremer-Grest polymer model see C. Svaneborg & R.

Level statistics and entanglement entropy of Rydberg dressed bosons in a triple-well potential
<p>We study the signatures of quantum chaos in Rydberg dressed bosonic atoms held in a 1 triple-well potential. Dynamics of the bosons are governed by an extended Bose-Hubbard model (EBHM) where long-range nearest-neighbor and next-nearest-neighbor interactions are induced by laser coupling the ground state to Rydberg state. We analyze the level statistics of the EBHM for finite number N of atoms through numerical diagonalization. In the presence of a tilting potential, the level statistics are Poissonian distribution for weak dressed interaction. It becomes a Wigner-Dyson distribution for strong interaction, signifying the emergence of quantum chaos. A hybrid distribution is obtained when the dressed interaction is much stronger than the hopping rate. Using the Fock basis, we further calculate dynamical evolution of the entanglement entropy. The maximal value (upper bound) of the entanglement entropy is proved to depend on particle numbers in the form ln(N + 1). It is found that the maximum of the time-averaged entanglement entropy appears when the chaos is strong. The location of the maximum as a function of the dressed interaction and tilting potential is independent of atom number N.</p>
Entangled Ecologies. Interactive Documentary between Living Archive, Responsible Witnessing and Relational Co-Creation
<p>The videoessay is also accessible: <a href="https://trametrami.avinus.org/publikationen/3-2023">https://trametrami.avinus.org/publikationen/3-2023</a></p> <p>Recent re-conceptualizations of participation as well as theories of digital transformation culture have shifted the notion of the archive seeing not so much as a static, institutional body but rather as a dynamic, living epistemic environments. Building on these approaches, this presentation discusses emerging phenomena in interactive documentary focusing on ecological emergency – seeing this crisis itself as a complex ecology of issues where images and conceptualization past, present and future meet. Taking paradigmatic projects addressing the issue of climate change – <em>The Shore Line</em> (2017) and <em>Climate Witness Project </em>(2019) – I suggest tentative answers to the question in which way i-docs can contribute to tackle complex change. Are there images from the past which help us to better cope with the present and to envision a more sustainable future? How can one raise awareness of immanent ecological risks when menace is almost invisible, unprecedented and un-imaginable? Is there a way to negotiate multifaceted entanglements through documentaries which are neither paralyzing ecodystopian narratives nor naive ecotopian success-stories? The hypothesis underlying my approach is that one possible solution resides in documentaries which are built on principles of pluri-perspectivity and polyphony to transcend dualisms and to build bridges leading from history to the forthcoming. Discourses from various traditions are brought into dialogue: theories of documentary film meet ecocriticism; network theory encounters reflections on the epistemic dimension of non-fiction; and concepts of co-creation and intervention are related to processes of witnessing, doing documentary and responsible action-taking.</p> <p> </p> <p>more information: <a href="https://did.avinus.org/">https://did.avinus.org/</a> and <a href="https://trametrami.avinus.org/publikationen">https://trametrami.avinus.org/publikationen </a></p>
