Is dark energy weakening?
/ Palanque-Delabrouille, Nathalie (speaker) (LBNL, US)
Making up 70% of the universe and responsible for its accelerated expansion, Dark energy is the biggest mystery in cosmology. A simple model where dark energy is described as a cosmological constant explains most of the observations of the past 20 years [...]

The Copernican Revolution, and how it almost became unnoticed and forgotten
/ Roszkowski, Leszek (speaker) (Astrocent at the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences and National Centre for Nuclear Research, Poland)
The Copernican Revolution — the heliocentric model of the Universe introduced by Nicolaus Copernicus — is considered as one of the most significant achievements in the history of science. And yet, it luckily happened despite many obstacles and even then it could have become unnoticed and forgotten [...]

Quantum Gravity and Predictions for our Universe
/ Vafa, Cumrun (speaker) (Harvard University)
In this talk I provide an executive summary of some of the recent progress that has been made in understanding some key features of quantum gravitational theories. This is rooted in lessons learned from the landscape of consistent solutions to string theory and captured by the principles of the Swampland program [...]

Status and Prospects of the JUNO neutrino experiment
/ Yifang, Wang (speaker) (Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences in Beijing)
The JUNO experiment located at Jiangmen in the south of China nearby Macau is primarily a reactor neutrino experiment at a baseline of 53 km. With a total target mass of 20 kt liquid scintillator, it can measure precisely the reactor neutrino spectrum to determine the mass hierarchy and to improve the precision of neutrino mixing parameters by an order of magnitude. [...]

Large-scale Electricity Storage
/ Llewellyn Smith, Chris (speaker) (Oxford University)
Electricity will meet an increasing fraction of the world’s growing energy needs as fossil fuels are phased out. In many countries, most will be provided by wind and solar. To match wind and solar, which are volatile, with demand, which is variable, they must be complemented by using wind and solar generated electricity that has been stored when there is an excess, and/or supply from large-scale flexible low-carbon sources, of which there are very few. [...]

On the Origin of Time
/ Hertog, Thomas (speaker) (KU Leuven)
Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary career was how the universe could have created conditions so perfectly hospitable to life.Pondering this mystery led him to study its big bang origin, but his early work ran into a crisis when the math predicted many big bangs producing many universes, most far too bizarre to harbor life.Holed up in theoretical physics departments across the globe, Hawking and I worked shoulder to shoulder for twenty years, to develop a novel quantum framework for early universe cosmology that could account for the emergence of life. At the heart of our cosmogony lies a theory of the beginning that predicts that time and indeed physics itself fade away back into the big bang.In this colloquium I recount our quest to get a grips on the origin of time, and the bold new take on some of the universe’s fundamentals we were led to. Short bio: Thomas Hertog is a theoretical cosmologist at the KU Leuven. [...]

Quantum matter and clock: from emergent phenomena to fundamental physics
/ Ye, Jun (speaker) (University of Colorado, Boulder)
Precise quantum state engineering, many-body physics, and innovative laser technology are revolutionizing the performance of atomic clocks and metrology, providing opportunities to explore emerging phenomena and probe fundamental physics. Recent advances include precise control of many-body interactions to achieve high accuracy, measurement of gravitation time dilation across a few hundred micrometers, and employment of spin squeezing for clock comparison..
