Imaging antiferromagnetic domains

2024. October 01.

BME researchers observed exceptionally strong non-reciprocal light absorption in LiCoPO4. They exploited this optical contrast to detect antiferromagnetic domains, which are usually hidden for conventional microscopy techniques. The findings were published in the Physical Review B as a Letter, as Editors' Suggestion, and a synopsis also highlights this study in the Physics Magazine.

Ultralong carrier lifetime in solar cells

2024. July 02.

Research on novel photovoltaic materials, done in collaboration between Semilab Zrt. and our Institute of Physics, is published in Advanced Energy & Sustainability Research. 
 
Novel, perovskite-based photovoltaic materials are expected to yield a new generation of solar cells with an increased efficiency, and harvesting a different part of the optical spectrum, compared to conventional silicon-based devices. One of the major research challenges in this field is to understand carrier lifetimes and the physical processes governing those. Scientists of BME Institute of Physics, in collaboration with Semilab Zrt. in Budapest in the framework of the Cooperative Doctoral Program, gained new insights along this research line. The study was published in June 2024 in the journal Advanced Energy & Sustainability Research, with open-access availability at this link.

Quantum Technology Summer in Budapest

2024. June 13.

Three subsequent quantum technology events take place between June 10th and 20th in Budapest, all co-organised by scientists of the BME Institute of Physics.
 
The Defects in Solids for Quantum Technologies (DSQT) conference takes place from June 10 to 14 at the Roland Eötvös University (ELTE). Research in the past few decades revealed that point defects in semiconductors can be used in all four main areas of quantum technology -- quantum computing, quantum simulation, quantum communication, as well as quantum sensing. The conference brings world-leading experts of the field to Budapest. Hungarian members of the international organizing committee hosting the event are Ádám Gali (HUN-REN Wigner Research Centre for Physics and BME Institute of Physics) and Viktor Ivády (ELTE).
 
On June 17-18, the meeting of the OpenSuperQPlus consortium, consisting of 28 European organizations, will take place in the BME Q building. The long-term goal of this Horizon Europe project, carried out in a strong  academic-industrial cooperation, is to develop a quantum computer based on superconducting technology, consisting of 1,000 quantum bits. Among the Hungarian research centers, BME's Institute of Physics and the  HUN-REN Wigner RCP participate in the OpenSuperQPlus project, providing theoretical support for the development of the quantum computer. The Budapest meeting is organized by János Asbóth and András Pályi on behalf of BME, and Orsolya Kálmán and Zoltán Zimborás on behalf of HUN-REN Wigner RCP.
 
On June 19-20, a conference on Recent Advances in Quantum Computing and Technology (ReAQCT) will take place at the Bosch Budapest Innovation Campus. The event is jointly organized by several universities and research centers in Budapest. BME is represented in the organizing committee by András Pályi (BME TTK), and in the program committee by János Asbóth (BME TTK) and Eszter Udvary (BME VIK).
 
The DSQT and ReAQCT conferences are supported by the Quantum Information National Laboratory of Hungary.
