Abstract: In the recently modernized Eötvös balance measurements the readout of the torsion wire angle position is a camera photo. The position is determined by reading the scale numbers and the centre of the picture with Fourier transformation enhanced computation methods. Then we can achieve a precision under the hundredth of the scale units. During a normal registration period, there are two photos per second and sometimes recalculations of longer periods are necessary. Our purpose of using the computational capacity of the Wigner GPU lab is to perform these long computations. Now we would like to elaborate on a monthlong registration period that could take several weeks in our normal computers. Later on, we would like to use the calculation capacity in case of necessity.

Abstract: In recent years, both experimental quantum computers and quantum algorithms have been significantly improved. The advantage of quantum over classical computation is that if multiple qubits get entangled, the dimensionality of the Hilbert-space increases exponentially, and thus a quantum computer might be exponentially faster at solving certain problems than a classical one. Apart from this, the laws of quantum mechanics enable such computations and communication protocols, that are totally infeasible using classical computers. However, experimental quantum computers accessible at the moment contain only a few dozens of qubits, and those are quite noisy as well. Hence, when developing quantum algorithms, it is indispensable to use high performance classical computers to simulate these quantum algorithms in a reasonable time for a reasonable cost. Furthermore, an important research area is the investigation of hybrid quantum-classical algorithms, where the use of modern GPUs is necessary along with the quantum processors.

Abstract: Mean motion resonances (MMRs) play an important role in shaping the dynamics of the Solar system bodies. MMRs in the Solar system usually occur between a planet and small bodies, e.g. the members of the Hilda group of asteroids are in a 3:2, while the Trojan asteroids are in a 1:1 MMR with Jupiter. Based on the geometrical meaning of the resonance variable, an efficient method has been introduced and described in Forgács-Dajka, Sándor & Érdi (2018), by which mean motion resonances can be easily found without any a priori knowledge of them. The efficiency of this method - named FAIR - is clearly demonstrated by using some known members of different families of asteroids being in mean motion resonances with a planet.

The Hungaria group is a family of asteroids in the main asteroid belt orbiting the Sun between the orbit of Mars and that of Jupiter. In this research we systematically apply the method FAIR to the Hungaria family objects to identify the dynamically relevant MMRs between them and Jupiter or Mars. Our investigation may help to find possible new subfamilies of the Hungaria group based on resonance, and besides, we examine whether there is any correlation between the physical properties and the dynamical parameters of asteroids.

Abstract: Inertial Confinement Fusion is a promising option to provide massive, clean, and affordable energy for humanity in the future. The present status of research and development is hindered by hydrodynamic instabilities occurring at the intense compression of the target fuel by energetic laser beams. NAno-Plasmonic, Laser Inertial Fusion Experiments (NAPLIFE) were proposed, as an improved way to achieve laser driven fusion. The improvement is the combination of two basic research discoveries:
(i) The possibility of detonations on space-time hyper-surfaces with time-like normal (i.e. simultaneous detonation in a whole volume)[1] and
(ii) to increase this volume to the whole target, by regulating the laser light absorption using nano-shells or nano-rods as antennas [2].
These principles can be realized in an in-line, one dimensional configuration, in the simplest way with two opposing laser beams as in particle colliders [3]. Such, opposing laser beam experiments were also performed recently. Here we study the consequences of the Laser Wake Field Acceleration (LWFA) if we experience it in a colliding laser beam set up. These studies can be applied to laser driven fusion, but also to other rapid phase transition, combustion, or ignition studies in other materials.

Abstract: In our previous project we have prooved our idea that the MAO-A enzyme is able to break down the N,N-DMT to the corresponding iminium cation via lower activation energy states, if the FAD could abstact a single proton from its environment to a certain position. Our goal is finding the energetically the most favourable way of this process.

Abstract: Hastlayer by Lombiq Technologies allows software developers of the .NET platform to utilize FPGAs as compute accelerators. It converts standard .NET constructs into equivalent hardware implementations, automatically enhancing the performance while lowering the power consumption of suitable algorithms. Developers keep writing .NET programs as usual, no hardware design knowledge is required.

Hastlayer needs to support FPGA boards specifically, and formerly it only supported one that was suitable for testing and creating proof of concepts, but not for high performance computing scenarios. The recently finished work in collaboration with Wigner RCP was about making it support high-performance FPGAs of the Microsoft Catapult platform. Wigner's task was to create the FPGA-side hardware framework that hosts the automatically generated hardware cores created by Hastlayer.

The current project is similar, but about making Hastlayer support all SDAccel-compatible Xilinx FPGAs. This will open up a wide range of possibilities for Hastlayer-accelerated applications by unlocking the large product line of high-performance SDAccel-compatible FPGAs running on premise, as well as in multiple public cloud computing providers.

Abstract: Although gravitational waves have been detected in 2016 with GW150914, but there are still many exotic cases to discover, e.g. binaries with Zoom-Whirl orbits, Super Massive Black Holes, etc. To examine such cases the Wigner RCP Gravitational group developed a software called CBwaves , that we would like to upgrade with the fourth terms of the post-Newtonian formalism and with its Hamiltonian formalism. Also we would like to enchance the runime of our code using parallelism.
