Our research interests involve theoretical and experimental high energy, particle and astro-particle physics, cosmology, physics of inflation and early Universe, in particular gravitational waves.
The lab has over 20 scientists from over six different countries. We are part of the CMS collaboration at CERN and of the LISA gravitational wave detector collaboration at the European Space Agency (ESA). We work to determine the fundamental nature of the universe through gravitational waves and other physics in the centre of excellence „Foundations of the Universe“ in collaboration with the University of Tartu and Tallinn Technical University.
The computing centre of the laboratory has a powerful cluster with 6000 cores and 4 PB of storage. We do CMS particle physics simulations, compute phase transitions in the early Universe, and other computations that need high performance computing. We take part in the ETAIS to develop the scientific computing infrastructure in Estonia.

Ville: We showe that realistic particle physics models can predict first-order phase transitions in the early universe that lead to the formation of primordial black holes with a distinguishable gravitational wave signature that is detectable with future observatories. [2/3]

Ville: selles töös näitasime, et realistlikud osakestefüüsika mudelid ennustavad esimest järku faasisiirdeid, milles tekivad ürgsed mustad augud ja mille gravitatsioonilainete signaali on võimalik tuleviku observatooriumides avastada. [3/3]

KBFI is part of the proto-collaboration for the development and realization of Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI). Several KBFI members contributed to the recent summary of the 2nd TVLBAI workshop: arxiv.org/abs/2412.14960. [1/2]

KBFI osaleb algavas kollaboratsioonis maapealse väga pika baasjoonega aatominterferomeetria (TVLBAI) välja arendamiseks ja teostamiseks. Mitmed KBFI teadlased panustasid hiljutise 2. TVLBAI konverentsi kokkuvõttesse: arxiv.org/abs/2412.14960 [2/2]

Antonio: Allowing space-time to be not only curved but also twisted, symmetry-breaking inflation (an old idea excluded by recent data) becomes viable again. [2/3]

Antonio: Kui aegruumi saab mitte ainult kõverdada, vaid ka väänata, siis tuleb sümmeetriat rikkuv inflatsioon (vana idee, mille lihtsamad teostused ei ole viimaste andmetega kooskõlas) jälle päevakorda. [3/3]

Torben: This result is an important step in deciphering the Higgs sector and shining light in one of the lesser explored corners of the Standard Model (SM).
We are approaching SMsensitivity fast, and these results promise interesting times are lying ahead. [2/3]— HEP @ KBFI/NICPB (@kbfihepsocial.bsky.social) Nov 22, 2024 at 1:42 PM
Torben: Meie teadustöö tulemus tähistab olulist edasiminekut Higgsi sektori lahtimõtestamisel ning valgustab seni suhteliselt vähe uuritud piirkonda StandardMudelis. Oleme kiiresti lähenemas SM-i tundlikkuse piirile, ning meie tulemused viitavad, et ees ootavad teaduslikult põnevad ajad. [3/3]
