Title: CP-violating inflation Abstract: I will introduce the novel phenomenon of CP-violating inflation which arises in models with several scalar doublets. The inert (without vacuum expectation value) doublets have a non-minimal coupling to gravity and play the role… Read More

DIAS scientists’ part of research team to record first ever detailed description of a volcanic eruption from Sierra Negra

A volcanic eruption in the Galápagos Islands has given scientists a fresh insight into how volcanoes behave and provided vital information that will help to predict future hazards on the islands. Irish scientists, based at Dublin Institute for… Read More

Title: Helicity leads to a Quantum Group in Classical Hydrodynamics Abstract: Helicity is the integral of the dot product of velocity and vorticity. It is famous as a conserved quantity of three dimensional hydrodynamics, shown by Moffat to… Read More

Title: Topological orders from centres in 3+1D Abstract: In the work of Kong and Wen [1] it is conjectured that (n+1)D topological orders can be described algebraically by braided fusion n-categories, satisfying a condition called “remote detectability”. In… Read More

Title: Gauge Theory Formulation of Hyperbolic Gravity Abstract: The talk will be based on my recent paper arXiv:2011.02108 (to appear in JHEP) and on an ongoing follow-up research. A tentative plan of the talk is as follows: Introduction:… Read More

Tensor-network Method to Simulate Strongly Interacting Quantum Thermal Machines

Speaker: Marlon Brenes (Trinity College Dublin)
Time: Thursday 11 February 2021, 4:00pm

Title: BV formalism: from physics to mathematics and back Abstract: This talk concerns the BV formalism, or rather its particular version compatible with perturbative algebraic quantum field theory. Its origins are in physics, in the works of Batalin-Vilkovisky,… Read More

Title: S-matrix and quantum exclusion of de Sitter and consequences.  Abstract: We discuss how quantum gravity excludes de Sitter and consequences of this exclusion for inflation and dark energy. Talk – Video Talk – Slides

Title: Causality in Quantum Field Theory Abstract: In 1993 , Rafael Sorkin argued that standard quantum measurement theory and relativistic causality are not compatible because of the existence of entangled quantum states . He showed this by devising experiments using entangled states which… Read More
