Novel s-wave superconducting phase of doped topological insulators.
Many of the topological insulators, in their naturally available form are not insulating in the bulk. It has been shown that some of these metallic compounds, become superconductor at low enough temperature and the nature of their superconducting phase is still widely debated. In this talk I show…
A la recherche du temps perdu....in quantum gravity
Fay Dowker - Imperial College London
Causal set quantum gravity is based on the marriage between the concept of causality as an organising principle more basic even than space or time and fundamental atomicity. Causal sets suggest novel possibilities for "dynamical laws" in which spacetime grows by the accumulation of new spacetime…
Completing Canonical Quantization
John Klauder - University of Florida
The process of canonical quantization:is reexamined with the goal of ensuring there is only one reality, where $\hbar>0$, in which classical and quantum theories coexist. Two results are a clarification of the effect of canonical coordinate transformations and the role of Cartesian coordinates…
Detectable signatures of compact binaries involving neutron stars
Vasileios Paschalidis - University of Illinois Urbana-Champaign
In this talk I will focus on two topics concerning compact binaries that involve a neutron star companion: a) the fate of and observable signatures from merging white dwarf-neutron star (WDNS) binaries, and b) electromagnetic signals from black hole - neutron star (BHNS) binaries. WDNS systems - the…
Resources
Tobias Fritz - Universität Innsbruck
One of the main challenges that we face both as individual persons and as a species concerns the distribution and use of resources, such as water, time, capital, computing power or negatively valued resources like nuclear waste. Also within theoretical physics, one frequently deals with resources…
Tackling the Challenges of Gravitational-Wave Astronomy
Kipp Cannon - University of Tokyo
Gravitational radiation promises to teach us many new things about the universe and the world around us, but all attempts to observe gravitational waves have so far been unsuccessful. I will discuss some of the challenges we need to overcome in our quest to detect this elusive form of energy, and…
Neutrino as Majorana zero modes
Zheng-Cheng Gu - Chinese University of Hong Kong
The existence of three generations of neutrinos and their mass mixing is a deep mystery of our universe. Majorana's elegant work on the real solution of Dirac equation predicted the existence of Majorana particles in our nature, unfortunately, these Majorana particles have never been observed. In…
Bipartite Graphs, Quivers and Gauge Theories
Yang-Hui He - University of London
We discuss how bipartite graphs on Riemann surfaces encapture a wealth of information about the physics of large classes of supersymmetric gauge theories, especially those with quiver structure and arising from the AdS/CFT context. The correspondence between the gauge theory, the underlying…
Detecting Modified Gravity in the Stars
Jeremy Sakstein - University of Pennsylvania
Screened Scalar-Tensor gravity such as chameleon and symmetron theories allow order one deviations from General Relativity on large scales whilst satisfying all local solar-system constraints. A lot of recent work has therefore focused on searching for observational signatures of these models and…
Processing quantum information with relativistic motion of atoms
Eduardo Martin-Martinez - University of Waterloo
We show that particle detectors, such as 2-level atoms, in non-inertial motion (or in gravitational fields) could be used to build quantum gates for the processing of quantum information. Concretely, we show that through suitably chosen non-inertial trajectories of the detectors the interaction…
Entanglement at strongly-interacting quantum critical points in 2+1D
Roger Melko - University of Waterloo
In two or more spatial dimensions, leading-order contributions to the scaling of entanglement entropy typically follow the "area" or boundary law. Although this leading-order scaling is non-universal, at a quantum critical point (QCP), the sub-leading behavior does contain universal physics…
A gauge theory generalization of the fermion-doubling theorem
John McGreevy - University of California, San Diego
This talk is about obstructions to symmetry-preserving regulators of quantum field theories in 3+1 dimensions. New examples of such obstructions can be found using the fact that 4+1-dimensional SPT states are characterized by their edge states. (Based on work in progress with S.M. Kravec.)
