Gravitational wave backgrounds from colliding exotic compact objects / Banks, Hannah (CERN ; Cambridge U., DAMTP) ; Grabowska, Dorota M. (CERN ; U. Washington, Seattle (main)) ; McCullough, Matthew (CERN)
Long baseline atom interferometers offer an exciting opportunity to explore mid-frequency gravitational waves. In this work we survey the landscape of possible contributions to the total 'gravitational wave background' in this frequency band and advocate for targeting this observable. [...]

Overcoming exponential volume scaling in quantum simulations of lattice gauge theories / Kane, Christopher F. (Arizona U.) ; Grabowska, Dorota M. (Washington U., Seattle ; CERN) ; Nachman, Benjamin (LBL, Berkeley) ; Bauer, Christian W. (LBL, Berkeley)
Real-time evolution of quantum field theories using classical computers requires resources that scale exponentially with the number of lattice sites. Because of a fundamentally different computational strategy, quantum computers can in principle be used to perform detailed studies of these dynamics from first principles. [...]

The study of real-time evolution of lattice quantum field theories using classical computers is known to scale exponentially with the number of lattice sites. [...]

Overcoming exponential scaling with system size in Trotter-Suzuki implementations of constrained Hamiltonians: 2+1 U(1) lattice gauge theories / Grabowska, Dorota M. (CERN) ; Kane, Christopher (Arizona U.) ; Nachman, Benjamin (LBL, Berkeley) ; Bauer, Christian W. (LBL, Berkeley)
For many quantum systems of interest, the classical computational cost of simulating their time evolution scales exponentially in the system size. [...]

Hamiltonian Formulations of Lattice Gauge Theories, with an eye towards Quantum Simulation* / Grabowska, Dorota (speaker) (CERN)
There are many fundamental questions in particle and nuclear physics that cannot be addressed via classical computing techniques. These include the equation of state for finite density nuclear matter, real-time dynamics of quantum field theories from first-principles and non-perturbative aspects of chiral gauge theories. [...]

Analytic expansions of two- and three-particle excited-state energies / Grabowska, Dorota Maria (CERN) ; Hansen, Maxwell T. (U. Edinburgh, Higgs Ctr. Theor. Phys.)
The last years have seen significant developments in methods relating two- and three-particle finite-volume energies to scattering observables. These relations hold for both weakly and strongly interacting systems, and studying their predictions in limiting cases can provide important cross checks as well as giving useful insights into the general formulae. [...]

Efficient Representation for Simulating U(1) Gauge Theories on Digital Quantum Computers at All Values of the Coupling / Bauer, Christian W. (LBNL, Berkeley) ; Grabowska, Dorota M. (CERN)
We derive a representation for a lattice U(1) gauge theory with exponential convergence in the number of states used to represent each lattice site that is applicable at all values of the coupling. At large coupling, this representation is equivalent to the Kogut-Susskind electric representation, which is known to provide a good description in this region. [...]

Analytic expansions of multi-hadron finite-volume energies. I. Two-particle states / Grabowska, Dorota M. (CERN) ; Hansen, Maxwell T. (U. Edinburgh (main))
We derive analytic expansions for the finite-volume energies of weakly-interacting two-particle systems, using the general relations between scattering amplitudes and energies derived by Lüscher and others. The relations hold for ground and excited states with both zero and non-zero total momentum in the finite-volume frame. [...]
