Opinion bubbles in the quantum Buridan's ass problem

Leonid Chaichenets, Jaroslav Novotný, Igor Jex +2

The quantum Buridan's ass problem concerns a network of interconnected nodes in which transitions between the nodes are governed by the laws of quantum mechanics. In such situation…

Out of Tune: Demystifying Noise-Effects on Quantum Fourier Models

Maja Franz, Melvin Strobl, Leonid Chaichenets +3

Variational quantum algorithms have received substantial theoretical and empirical attention. As the underlying variational quantum circuit (VQC) can be represented by Fourier seri…

Complex Interpolation and the Monotonicity in the Spatial Integrability Parameter of Exponentially Weighted Modulation Spaces

Leonid Chaichenets, Jan Hausmann

We introduce the notion of common retraction and coretraction for families of Banach spaces, formulate a framework for identifying interpolation spaces, and apply it to modulation…

Higher order NLS with anisotropic dispersion and modulation spaces: a global existence and scattering result

Leonid Chaichenets, Nikolaos Pattakos

In this paper we transfer a small data global existence and scattering result by Wang and Hudzik to the more general case of modulation spaces where $q =…

Local well-posedness for the nonlinear Schrödinger equation in the intersection of modulation spaces

Leonid Chaichenets, Dirk Hundertmark, Peer Christian Kunstmann +1

We introduce a Littlewood-Paley characterization of modulation spaces and use it to give an alternative proof of the algebra property, somehow implicitly contained in Sugimoto (201…

Interference and Throughput in Aloha-based Ad Hoc Networks with Isotropic Node Distribution

Ralph Tanbourgi, Holger Jäkel, Leonid Chaichenets +1

We study the interference and outage statistics in a slotted Aloha ad hoc network, where the spatial distribution of nodes is non-stationary and isotropic. In such a network, outag…
