Counterions between walls with surface charge modulations: Exact Poisson-Boltzmann solutions
Ladislav Šamaj
We study the thermal equilibrium of a classical system of identical point charges moving between two walls with parallel surfaces at a distance , charged symmetrically with posi…
Prediction of coherent interfaces between diamond and clathrate structures
Eva Pospíšilová, Marek Mihalkovič
Diamond (or its binary zincblende variant)-type structure can form coherent interface with clathrate type II via the common transitional layer known previously as a -d…
Efficient implementation of single particle Hamiltonians in exponentially reduced qubit space
Martin Plesch, Martin Friák, Ijaz Ahamed Mohammad
Current and near-term quantum hardware is constrained by limited qubit counts, circuit depth, and the high cost of repeated measurements. We address these challenges for solid stat…
AI4EOSC: a Federated Cloud Platform for Artificial Intelligence in Scientific Research
Ignacio Heredia, Álvaro López García, Fernando Aguilar Gómez +28
The rapid growth of Artificial Intelligence and Machine Learning in scientific research has highlighted a gap between industry-standard MLOps tools and platforms, and the unique re…
Photothermal resistivity alignment of optical fibers to SNSPD
Martin Baránek, Dušan Lorenc, Tomáš Ščepka +5
We demonstrate a straightforward optoelectronic fiber alignment technique for superconducting nanowire single-photon detectors (SNSPDs) that exploits the temperature-dependent resi…
Development of soft and hard skills of high-school students via Young Physicists' Tournament
Sergej Faletič, Assen Kyuldjiev, Thomas Lindner +9
The Young Physicists' Tournament (YPT) inspires high-school students to immerse themselves into an inquiry process closely resembling the real physics research. Using questionnaire…
Geometric potential for a Bose-Einstein condensate on a curved surface
Sheilla M. de Oliveira, Natália Salomé Móller
We compute the ground state of a Bose-Einstein condensate confined on a curved surface and unravel the effects of curvatures. Starting with a general formulation for any smooth sur…
1D fluids with repulsive nearest-neighbour interactions: Low-temperature anomalies
Igor Travěnec, Ladislav Šamaj
A limited number of 2D and 3D materials under a constant pressure contract in volume upon heating isobarically; this anomalous phenomenon is known as the negative thermal expansion…
Contact value theorem for electric double layers with modulated surface charge density
Ladislav Šamaj
The contact value theorem was originally derived for Coulomb fluids of mobile charged particles in thermal equilibrium, in the presence of interfaces carrying a {\em uniform} surfa…
Characterisation of individual gates using twirling circuits
David Amaro-Alcalá
We present a method to characterise qubit gates. Utilising the supermap formalism, we create a scheme for deterministic single-qubit gate analysis. Our approach introduces a new tw…
Strong Charge-Photon Coupling in Planar Germanium Enabled by Granular Aluminium Superinductors
Marián Janík, Kevin Roux, Carla Borja Espinosa +11
High kinetic inductance superconductors are gaining increasing interest for the realisation of qubits, amplifiers and detectors. Moreover, thanks to their high impedance, quantum b…
Effective interaction between guest charges immersed in 2D jellium
Ladislav Šamaj
The model under study is an infinite 2D jellium of pointlike particles with elementary charge , interacting via the logarithmic potential and in thermal equilibrium at the inver…
Advantages of quantum communication revealed by the reexamination of hyperbit theory limitations
Giovanni Scala, Seyed Arash Ghoreishi, Marcin Pawłowski
Pawłowski and Winter's hyperbit theory, proposed in 2012, presented itself as an alternative to quantum theory, suggesting novel ways of redefining entanglement and classical commu…
Universal validity of the second law of information thermodynamics
Shintaro Minagawa, M. Hamed Mohammady, Kenta Sakai +2
Adiabatic measurements, followed by feedback and erasure protocols, have often been considered as a model to embody Maxwell's Demon paradox and to study the interplay between therm…
Resource-efficient utilization of quantum computers
Ijaz Ahamed Mohammad, Matej Pivoluska, Martin Plesch
The current state of quantum computing is commonly described as the Noisy Intermediate-Scale Quantum era. Available computers contain a few dozens of qubits and can perform a few d…
Search for damped oscillating structures from charged pion electromagnetic form factor data
Erik Bartoš, Stanislav Dubnička, Anna Zuzana Dubničková
The damped oscillating structures recently revealed by a three parametric formula from the proton ``effective'' form factor data extracted of the measured total cross section $σ^{b…
Control of vortex chirality in a symmetric ferromagnetic ring using ferromagnetic nanoelement
Uladzislau Makartsou, Mathieu Moalic, Mateusz Zelent +2
Controlling the vortex chirality in ferromagnetic nanodots and nanorings has been a topic of investigation for the last few years. Many control methods have been proposed and it ha…
Exact two-component TDDFT with simple two-electron picture-change corrections: X-ray absorption spectra near L- and M-edges of four-component quality at two-component cost
Lukas Konecny, Stanislav Komorovsky, Jan Vicha +2
X-ray absorption spectroscopy (XAS) has gained popularity in recent years as it probes matter with high spatial and elemental sensitivity. However, the theoretical modelling of XAS…
Electric double layers with modulated surface charge density: Exact 2D results
Ladislav Šamaj
Electric double layers (EDL) with counterions only, say electrons with the elementary charge , in thermal equilibrium at the inverse temperature are considered. In particul…
Anisotropic deformation of the 6-state clock model: Tricritical-point classification
Maria Polackova, Andrej Gendiar
The two-dimensional -state clock models exhibit the Berezinskii-Kosterlitz-Thouless (BKT) transition for since they are a subset of the isotropic XY model. We examine t…
Pauli component erasing quantum channels
Jose Alfredo de Leon, Alejandro Fonseca, Francois Leyvraz +2
Decoherence of quantum systems is described by quantum channels. However, a complete understanding of such channels, especially in the multi-particle setting, is still an ongoing d…
Strength of Correlations in a Silver Based Cuprate Analogue
Riccardo Piombo, Daniel Jezierski, Henrique Perin Martins +10
AgF2 has been proposed as a cuprate analogue which requires strong correlation and marked covalence. On the other hand, fluorides are usually quite ionic and 4d transition metals t…
Quantum dynamics is not strictly bidivisible
