Continuous Variables Quantum Algorithm for Solving Ordinary Differential Equations / Barthe, Alice (CERN) ; Grossi, Michele (CERN) ; Tura, Jordi (U. Leiden (main)) ; Dunjko, Vedran (U. Leiden (main))
Solving Ordinary Differential Equations (ODE) is important for a broad range of domains, such as engineering, weather forecast, and finance. Most quantum algorithms proposed to solve them revolve around transforming ODEs into a system of linear equations, in order to benefit from the exponential advantage promised by the HHL algorithm.

Quantum LAN: On-Demand Network Topology via Two-colorable Graph States / Mazza, Francesco (CERN ; Naples U.) ; Caleffi, Marcello (CERN ; Naples U. ; Unlisted, IT) ; Cacciapuoti, Angela Sara (CERN ; Naples U. ; Unlisted, IT)
In Quantum Local Area Networks (QLANs) - the near-term building block of the Quantum Internet - the choice of the physical network topology is not so restrictive and binding as in classical LAN in terms of communication capabilities among the network nodes. And the rationale for this is the entanglement-enabled connectivity induced by multipartite entangled states. [...]

Computational Benefits Using an Advanced Concatenation Scheme Based on Reduced Order Models for RF Structures / Heller, Johann (U. Rostock) ; Flisgen, Thomas (U. Rostock) ; Van Rienen, Ursula (U. Rostock)
The computation of electromagnetic fields and parameters derived thereof for lossless radio frequency (RF) structures filled with isotropic media is an important task for the design and operation of particle accelerators. Unfortunately, these computations are often highly demanding with regard to computational effort. [...]

Measurement of Higgs boson parameters at the LHC / Dührssen, M (Phys. Inst., Freiburg U., Germany)
If there is a Standard Model like Higgs boson, it should be detected at the LHC. After this discovery it will be important to measure the properties of this particle. [...]

Standing torsional waves in a fully saturated, porous, circular cylinder / Solorza, S ; Sahay, P N
For dynamic measurement of the elastic moduli of a porous material saturated with viscous fluid using the resonance-bar technique, one also observes attenuation. In this article we have carried out the solution of the boundary-value problem associated with standing torsional oscillations of a finite, poroelastic, circular cylinder cast in the framework of volume-averaged theory of poroelasticity.

On time-domain and frequency-domain MMSE-based TEQ design for DMT transmission / Vanbleu, K ; Cuypers, G ; Moonen, M ; Ysebaert, G
We reconsider the minimum mean square error (MMSE) time-domain equalizer (TEQ), bitrate maximizing TEQ (BM-TEQ), and per-tone equalizer design (PTEQ) for discrete multitone (DMT) transmission and cast them in a common least-squares (LS) based framework. The MMSE- TEQ design criterion can be formulated as a constrained linear least-squares (CLLS) criterion that minimizes a time-domain (TD) error energy. [...]

Eigenphases of the S-matrix at high energy / Sertorio, L ; Toller, M
In the spirit of a statistical approach to the S-matrix, the authors discuss the concept of resonant state and are led to generalize the eigenphase formalism to many-particle processes. They show that the object to be considered is the connected part of the S-matrix at fixed total four-momentum and they give strong arguments in favour of the conjecture that this operator is compact.

Supergauge invariance and the Gell-Mann-Low eigenvalue / Ferrara, Sergio ; Iliopoulos, John ; Zumino, B ; Iliopoulos, J
The connections among supergauge, scale and conformal invariance are elucidated on the example of a renormalizable field theory model. For the massless model at the Gell-Mann-Low eigenvalue, a non-perturbative argument leads to the contradictory result that it can only describe a free field theory. [...]
