Are we in the multiverse?
Prof. Hiranya Peiris participated in a German/French TV show called “42” about the multiverse, which included a discussion of using analogue experiments to probe the predictions of the eternal inflation multiverse. The episode featured simulations of analogue false vacuum decay created by postdoc Alex Jenkins within the QSimFP team. <br> Youtube links: <br> <a href= 'https://www.youtube.com/watch?v=fTc0s6sNDlM'>German version </a>, <a href= 'https://www.youtube.com/watch?v=D6shp_-HKp4'>French version </a>
Jan. 4, 2024New calculations show how experiments will recreate early-universe quantum effects
Congratulations to CPI postdoctoral researcher Alex Jenkins for his paper on “Analog vacuum decay from vacuum initial conditions”, selected as an editor’s highlight by Physical Review D. The work is part of an interdisciplinary effort to study profound questions about the Universe’s origins by simulating them in tabletop experiments, using ultra-cold atoms to mimic quantum aspects of the opening moments of our cosmos. Using theoretical calculations and numerical simulations, Jenkins and his co-authors delved into how this can be accomplished. They showed that these experiments can indeed replicate quantum processes in the early Universe, using experimental conditions that are within the reach of current technologies. <br> <br> Commenting on the results, lead author Dr Alex Jenkins said “Quantum analogues are fast emerging as a vital tool for understanding the Universe. It’s been really exciting to play a part in this developing area, and to forge new connections with our experimental colleagues.” Co-author and Cosmoparticle Initiative director Prof Andrew Pontzen added, “this work grew out of Cosmoparticle Initiative collaborations, and it’s truly exciting to see it mature and receive recognition. None of us can wait to see the first results from the lab experiment now being built at Cambridge University”. <br> <br> The work was performed as part of the Quantum Simulators for Fundamental Physics (<a href = 'https://qsimfp.org/'>QSimFP</a>) consortium, with authors from UCL, University of Cambridge, Nottingham University, the University of Toronto and Perimeter Institute for Theoretical Physics. QSimFP is funded by UKRI’s <a href = 'https://www.ukri.org/what-we-do/browse-our-areas-of-investment-and-support/quantum-technologies-for-fundamental-physics/'>Quantum Technology for Fundamental Physics</a> programme. <br> <br> <a href = 'https://journals.aps.org/prd/abstract/10.1103/PhysRevD.109.023506'> Analog vacuum decay from vacuum initial conditions</a> <br> <br> <a href = 'https://profiles.ucl.ac.uk/83826'>Alex Jenkins' profile</a>
Nov. 14, 2023UK Quantum Fluids Network webinar
Dr Patrik Svancara gave a talk for the UK Quantum Fluids Network summarising the most recent results obtained in the Quantum black hole simulator facility at the University of Nottingham. We thank the organisers for the invitation and we are looking forward for future exciting talks that can be accessed from the <a href = "https://uk-quantum-fluids-network.github.io/webinars/">network website</a>. Watch the recording of Patrik's talk in the <a href = "https://qsimfp.org/yt_media/"> media section </a> or read the supporting paper on <a href = "https://arxiv.org/abs/2308.10773"> arXiv</a>.
April 20, 2023Kids on Campus April 2023
On April 20th the ARTlab hosted a Kids on Campus workshop, where 60 year 5 Primary School Pupils joined the QSimFP labs, see images below. The Black Hole Discovery Day was a half-day workshop, with a lecture, lab tour, ARTlab activity and visit to the library. The Nottingham QSimFP team joined the pupils for lunch, using the opportunity to introduce themselves, as well as answering any outstanding questions.
