Celestial amplitudes from flat space limits of AdS Witten diagrams
Ana-Maria Raclariu - King's College London
The search for pragmatic observables of quantum gravity remains at the forefront of fundamental physics research. A large set of ideas collectively known as the gauge-gravity duality have proven fruitful in tackling this problem. While such a duality is believed to universally govern gravitational…
Effective Field Theory of the waterfall phase in hybrid inflation
Maria Mylova - University of Tokyo
We examine the validity of the classical approximation of the waterfall phase transition in hybrid inflation from an effective field theory (EFT) point of view. The EFT is constructed by integrating out the waterfall field fluctuations, up to one-loop order in the perturbative expansion. Assuming…
From single-gap to multi-gap topological materials
Bartomeu Monserrat - University of Cambridge
Topology has become a powerful tool to classify and understand materials. The standard paradigm divides the energy bands into two groups separated by a gap, or with at most some low-dimensional band crossings. Single-gap topological materials include topological insulators, Chern insulators, and…
Exact results for metallic quantum critical points
Hart Goldman - Massachusetts Institute of Technology (MIT)
I discuss how exact, non-perturbative results can be obtained for both optical transport and static susceptibilities in “Hertz-Millis” theories of Fermi surfaces coupled to critical bosons. Such models possess a large emergent symmetry and anomaly structure, which we leverage to fix these quantities…
Probing the String Axiverse with Galaxy Surveys
Alex Lague - University of Pennsylvania
String theory suggests the existence of multiple axion species forming what is known as an “axiverse”. The axions in this model are thought to have logarithmically-distributed masses extending far below 10^{-21} eV, leading to the presence of ultralight axions. The latter have astrophysical de…
Studying new physics with nuclear spins
Will Terrano - Arizona State University
I will discuss the wide - range of new physics that can be probed with nuclear-spin comagnetometers, from EDM measurements to dark matter direct detection experiments. I will outline the potential for improvement in these measurements, and how improved quantum control could have a significant impact…
From Neural density Operators to Tensor Networks
Filippo Vincentini - L'Ecole Polytechnique Federale de Lausanne (EPFL)
In this talk I will discuss recent advances in Neural-Network parametrisations of pure and mixed quantum states that can be efficiently sampled. In the first part I will generalise the Neural Density Operator ansatz originally proposed by Torlai and Melko by combining two general ingredients that…
GWs from high-quality axionic defects
Oriol Pujolas - New York University (NYU)
The axion solution to the strong CP problem has many virtues but it suffers from the so-called quality problem. This problem is avoided in heavy axion realizations which, however, are harder to probe experimentally. I will show how generic heavy axion models can be tested in current and future…
