 Making High-Precision Gravitational Waves to Explore the Dark Universe</a>
 \nby Alessandra Buonanno (MPIGP Potsdam) as part of XXVI IFT Christmas Wor
 kshop\n\n\nAbstract\nThe solution of the two-body problem in General Relat
 ivity has been crucial in observing gravitational waves from binary system
 s composed of black holes and neutron stars\, and inferring their astrophy
 sical\, cosmological and gravitational properties. I will review the theor
 etical groundwork that has enabled these observations\, and discuss recent
  theoretical advances aimed at predicting highly accurate waveform models 
 for future detectors on the ground and in space. Finally\, I will highligh
 t some interesting observational findings obtained recently by the LIGO an
 d Virgo detectors.\n

 The Hubble Tension</a>\nby George Efstathiou (Kavli Institute for Cosmolog
 y\, Cambridge) as part of XXVI IFT Christmas Workshop\n\n\nAbstract\nI wil
 l review the constraints on H_0 from the Planck CMB measurements and compa
 re the best fit Planck model with recent results from ACTpol. The CMB valu
 e of H_0 is secure\, yet is in tension with Cepheid based measurements of 
 H_0.  Although the CMB  value is based on the Lambda CDM cosmology\, there
  has been no compelling theoretical modification of the model that can exp
 lain the tension. I will therefore explore  whether systematic errors may 
 be affecting the Cepheid distance scale and if so\, what must these errors
  look like.\n

 The XENON1T excess\, interpretations and implications</a>\nby Manfred Lind
 ner (Max Planck Institute for Nuclear Physics\, Heidelberg) as part of XXV
 I IFT Christmas Workshop\n\n\nAbstract\nThe XENON1T experiment aims at det
 ecting signatures of dark matter. The latest analysis showed\, however\, a
 n unexpected excess of events with low recoil energy. The talk will cover 
 in detail how the signal is obtained and different interpretations of this
  excess. The signal might point to new physics and several theoretical dir
 ections and their implications for future measurements and other experimen
 ts will be discussed.\n

 The fate of hints: recent developments in neutrino physics</a>\nby Thomas 
 Schwetz-Mangold (Karlsruhe Institute of Technology) as part of XXVI IFT Ch
 ristmas Workshop\n\n\nAbstract\nFinite neutrino mass points to new physics
  beyond the Standard Model. In this talk I give an overview over recent re
 sults in neutrino physics\, including the results of a combined analysis o
 f latest neutrino oscillation data. We comment on the implications of this
  years results for the type of neutrino mass ordering (normal versus inver
 ted) and on the status of leptonic CP violation within the minimal 3-flavo
 ur framework. I review the status of absolute neutrino mass searches and s
 earches for lepton-number violation. I will briefly discuss some examples 
 for searches for more exotic physics in the neutrino sector\, including st
 erile neutrinos. The guidline of my talk will be various "hints" for stand
 ard as well as non-standard physics\, which have been around for some time
  in neutrino data\, and their fate due to recent developements.\n

 Collider Physics and Machine Learning</a>\nby Jesse Thaler (MIT) as part o
 f XXVI IFT Christmas Workshop\n\n\nAbstract\nModern machine learning has h
 ad an outsized impact on many scientific fields\, and particle physics is 
 no exception.  What is special about particle physics\, though\, is the va
 st amount of theoretical and experimental knowledge that we already have a
 bout many problems in the field.  In this talk\, I draw on examples from c
 ollider phenomenology and quantum chromodynamics to highlight the fascinat
 ing interplay between theoretical principles and machine learning strategi
 es.\n

 The Information Paradox in the Age of Holographic Entanglement Entropy</a>
 \nby Netta Engelhardt (MIT) as part of XXVI IFT Christmas Workshop\n\n\nAb
 stract\nThe black hole information paradox — whether information escapes
  an evaporating black hole or not —  remains one of the greatest unsolve
 d mysteries of theoretical physics. The apparent conflict between validity
  of semiclassical gravity at low energies and unitarity of quantum mechani
 cs has long been expected to find its resolution in the deep quantum gravi
 ty regime. Recent developments in the holographic dictionary and in partic
 ular its application to entanglement\, however\, have shown that a semicla
 ssical analysis of gravitational physics has a hallmark feature of unitary
  evolution. I will describe this recent progress and discuss some potentia
 l new avenues for working towards a resolution of the information paradox.

 Toward quantum simulation of systems of relevance to nuclear and particle 
 physics</a>\nby Zohreh Davoudi (U. Maryland) as part of XXVI IFT Christmas
  Workshop\n\n\nAbstract\nA vibrant program has formed in recent years in v
 arious scientific disciplines to take advantage of near-term and future qu
 antum-simulation and quantum-computing hardware to study complex quantum m
 any-body systems\, building upon the vision of Richard Feynman for quantum
  simulation. Such activities have recently started in nuclear and particle
  physics\, hoping to bring new and powerful experimental and computational
  tools to eventually address a range of challenging problems in strongly i
 nteracting quantum field theories and nuclear many-body systems. In this t
 alk\, I first motivate the need for quantum simulation in nuclear physics 
 by showcasing some of the state of the art in our classical simulations an
 d discussing the existing challenges to move ahead. I will then review a n
 umber of important developments in quantum simulation\, including proposal
 s for simulating strongly interacting field theories with the ultimate goa
 l of studying strong dynamics of quarks and gluons\, and of nucleons. Some
  of the requirements for hardware technologies that are expected to enable
  both the analog simulations and the digital quantum computations of these
  problems will be enumerated\, and an experiment-theory co-development pro
 gram will be motivated with an emphasis on trapped-ion platforms.\n

 A superconducting Qbit as a universal approximant</a>\nby Pol Forn-Diaz (I
 FAE - Barcelona Supercomputing Center) as part of XXVI IFT Christmas Works
 hop\n\n\nAbstract\nA single qubit can approximate any bounded complex func
 tion as stored in the degrees of freedom defining the quantum state. This 
 result is analogue to two known theorems ensuring approximations for funct
 ions\, namely Fourier series and the Universal Approximation Theorem (UAT)
 \, that holds for neural networks with a large enough single\, intermediat
 e hidden layer. The single qubit circuit becomes more accurate as the inde
 pendent function variable is re-uploaded in an increasing number of gates\
 , analogous to the classical methods that grow in accuracy with an increas
 ed number of intermediate steps. We further implement a one-qubit approxim
 ant in a real superconducting qubit device consisting of a transmon qubit 
 in a three-dimensional cavity\, explicitly showing how the ability to desc
 ribe a set of functions improves with the depth of the quantum circuit.\n
