Title: Green Functions for Black Hole Spacetimes: Wave Propagation, Self-Force, Stability and Quantum Properties Abstract: Field perturbations of black hole spacetimes satisfy a wave equation, for which crucial objects are its classical (e.g., retarded) and quantum (e.g., Feynman)… Read More

From mid-May 2024, the DIAS Planetary Magnetospheres group (dias.ie/planetary) is offering a 2-to-3-month studentship for a motivated candidate to work with the group on the topic of Jupiter’s moon Europa. Jupiter’s moon Europa is thought to harbour an… Read More

Title: Three-dimensional Massive Gravity and the Fractional Quantum Hall Effect Abstract: In this talk I will compare the massive spin-2 modes that have been observed in the Fractional Quantum Hall effect with the Fierz-Pauli description of massive spin-2… Read More

Title: Non-Relativistic Gravity Abstract: I will discuss the 1/c expansion of general relativity where c is the speed of light. At low orders this gives Newton-Cartan gravity and generalisations thereof. At higher orders (and weak fields) this can… Read More

Title: Entanglement Resolution and Boundary Conformal Field Theory Abstract: Conformal field theory is playing an essential role in developing our understanding of entanglement in many-body systems and field theory. I will discuss how it allows one to access… Read More

Title: Maxwell Theory of Fractons Abstract: In this talk I will show that the main properties of the fracton quasiparticles can be derived from a generalized covariant Maxwell-like action. Starting from a rank-2 symmetric tensor field, a partially symmetric… Read More

Title: Staggered Bosons Abstract: I will discuss a novel construction of field theories based on the idea that one has only a half boson degree of freedom per  lattice site. Basically, instead of having a pair of canonical  conjugate commuting variables… Read More

Title: Monopoles and Baryons from Sphalerons and Instantons Abstract: I will discuss non-perturbative quantum field theory phenomena in theStandard Model of particle physics and its extensions, described bysemiclassical sphaleron and instanton solutions. In the StandardModel, they violate baryon number and therefore play an important rolein… Read More

Title: Physics Opportunities of CEvNS Experiments Abstract: CEvNS experimental facilities provide a rather rich environment for precise measurements of SM parameters and searches of new physics. In this talk, I will discuss a few aspects of this program involving… Read More
