New European project „Neuromorphic Polariton Accelerator” (PolArt)

Tuesday, 22 August 2023 09:10 |

MBE Laboratory will collaborate with Warsaw University on the Horizon Europe Pathfinder project “Neuromorphic Polariton Accelerator”, acronym: PolArt. The goal of the project, leaded by prof. Barbara Piętka, is to demonstrate a new way to build artificial intelligence-dedicated circuits using polariton neural networks as optical accelerators. Prof. Czesław Skierbiszewski team will be focused on the design, fabrication and integration of the micro-LEDs and their arrays, that are the key elements to inject and modulate the signal in the waveguides.

The project aims to build a network that performs binary operations based on polariton microcavities. The basic element that enables effective binary operations are semiconductor microcavities. Strong coupling of the microcavity modes with excitons result in gigantic nonlinearities that are required for efficient calculations. The fact that polaritons operating room temperature was recently demonstrated, promises to have a real impact on the technologies of the future. Research units involved in the project have recently shown that this state of matter is extremely interesting in terms of speed and efficiency when used to implement artificial neural networks.

Thanks to this new concept device, complex applications related to neural-like processing, will be efficiently implemented, therefore enabling neuromorphic computation to be done in small devices that cannot rely on remote, large bandwidth connection. This proposal benefits from the contribution of several complementary partners coming from many different research areas (material science, physics, optics, chemistry, genetics) and industrial participants that assure the interdisciplinarity and technological oriented target.

Spotkanie studyjne dla mediów w siedzibie CENTERA

Monday, 11 September 2023 12:01 |

W najbliższy czwartek 14 września 2023 r. o godzinie 12.00 przy ul. Poleczki 19 w Warszawie - w Laboratoriach CENTERA mieszczących się Centrum Zaawansowanych Materiałów i Technologii CEZAMAT Politechniki Warszawskiej - odbędzie się spotkanie studyjne dla mediów.

Zaproszenie do mediów kierowane jest w imieniu prof. Macieja Żylicza, prezesa Fundacji na rzecz Nauki Polskiej oraz prof. dr hab. Wojciech Knapa, dyrektora Międzynarodowego Centrum Badań i Zastosowań Terahercowych (CENTERA) działającego w ramach Instytutu Wysokich Ciśnień Polskiej Akademii Nauk.

Wydarzenie będzie okazją do zapoznania się z najnowszymi osiągnięciami naukowymi międzynarodowych zespołów ekspertów prowadzących badania nad promieniowaniem terahercowym (THz). Promieniowanie terahercowe to fale o wysokiej częstotliwości, mieszczące się między mikrofalami a promieniowaniem podczerwonym. CENTERA pracuje nad rozwiązaniami, które mogą znaleźć zastosowanie w telekomunikacji, bezpieczeństwie, medycynie czy produkcji przemysłowej. W spotkaniu o sukcesach CENTERA i przyszłości eksperymentów opowiedzą eksperci z dziedziny fizyki, elektroniki, optyki, materiałoznawstwa czy wdrażania wyników badań naukowych w gospodarce. Z racji na bliską współpracę CENTERA z ośrodkami naukowymi z Francji, w spotkaniu planowana jest obecność Ambasadora Republiki Francuskiej w Polsce.

Recent ambient and high-pressure studies of iron-based superconductors by UNIPRESS (Editor's Choice)

Tuesday, 29 August 2023 08:19 |

The research team of Dr. Singh from NL-6 Laboratory of Superconductors has recently published two interesting publications on iron-based superconductors (FBS); both in an open access journal Materials (Impact factor 3.4).

In the first paper, the effect of cometal addition has been studied and reported for FBS at ambient pressure, where the enhancement of the superconducting transition (T_c) and critical current (J_c) properties were observed due to the improvement of the intergrain connections and pinning centres. This paper is published by M. Manasa, M. Azam, T. Zajarniuk, R. Diduszko, T. Cetner, A. Morawski, A. Wiśniewski, and Shiv J. Singh entitled “Cometal Addition Effect on Superconducting Properties and Granular Behaviours of Polycrystalline FeSe_0.5Te_0.5” (Materials 16, 2892 (2023) https://doi.org/10.3390/ma16072892).

In the second work, optimization of Fe(Se,Te) physical properties was carried out utilizing the high gas pressure and high-temperature approach (HP-HTS). In comparison to the ambient pressure approach, HP-HTS under optimal growth conditions significantly improved the critical current density, the pinning properties, and the transition temperature. This study demonstrates that the high-pressure synthesis method can be a novel approach to studying FBS materials in order to improve sample quality, achieve further superconducting property enhancements, and advance the development of their magnetic applications, particularly for superconducting wires and tapes. This paper is published by M. Azam, M. Manasa, T. Zajarniuk, R. Diduszko, T. Cetner, A. Morawski, J. Więckowski, A. Wiśniewski, and Shiv J. Singh entitled “High-Pressure Synthesis and the Enhancement of the Superconducting Properties of FeSe_0.5Te_0.5” (Materials 16, 5358 (2023) https://doi.org/10.3390/ma16155358).

Note that this is EDITOR's CHOICE ARTICLE, selected by Editors to be particularly interesting to readers and important in the respective research area.

Unipress and CEA-LETI cooperation

Tuesday, 01 August 2023 11:53 |

On July 23-30, 2023 our colleagues Dr eng. Paweł Kempisty and Dr Konrad Sakowski visited Commissariat à l'énergie atomique et aux énergies alternatives, Laboratoire d’électronique et de technologie de l’information (CEA-LETI, Grenoble, France). The purpose of this visit, financed by NAWA agency, was to perform research, discuss the results obtained so far and to plan future collaboration between CEA-LETI and Unipress scientists.
