Optical lattice clocks with bosonic/fermionic Sr and with the other atomic elements
Speaker(s): Hidetoshi Katori
Abstract: To date, optical clocks based on singly trapped ions1) and ultracold neutral atoms trapped in the Stark-shift-free optical lattices2) are regarded as promising candidates for future atomic clocks. So far “optical lattice clocks” have been evaluated with uncertainty of 1×10-15 (ref. 3)) limited ... read more

Nuclear binding and the light quark masses – Dynamics and constraints
Speaker(s): John Donoghue
Abstract: I will describe a method of understanding how the nuclear binding energies depend on the masses of the light quarks. This is useful in applications ranging from anthropic constraints to equivalence principle tests and bounds on the time variation on the quark masses.

Recent and Local Variations and Unified Models
Speaker(s): Thomas Dent
Abstract: Precision tests of Local Position Invariance (LPI) involve many different methods in atomic, nuclear and gravitational physics, astrophysics and cosmology, and many different epochs and environments. We present some methods for comparing or combining different methods, either in a model-independent ... read more

21 cm radiation: A new probe of fundamental physics
Speaker(s): Rishi Khatri
Abstract: New low frequency radio telescopes currently being built open up the possibility of observing the 21 cm radiation before the Epoch of Reionization in the future, in particular at redshifts 200 ≥ z ≥ 30, also known as the dark ages. At these high redshifts, Cosmic Microwave Back-ground (CMB) radi... read more
