Reformulation of the pionless effective field theory for practical few- and many-body applications
Silas R. Beane, Roland C. Farrell, Cameron P. Shotwell +1
The effective field theory (EFT) of contact forces which describes few-nucleon systems at distance scales larger than the pion Compton wavelength ca…
A Reconstruction of Michelson Interference from On--Off Detection Statistics
Kim Myung-Whun
This paper reconstructs the Michelson interference phenomenon based solely on the binary (on-off) statistics of a single-photon counter and macroscopic path-difference data, withou…
Local universality of non-local quantum resources in rotationally invariant scattering
Silas R. Beane, Roland C. Farrell
Elastic scattering can generate entanglement and non-local magic between the spins of the two outgoing particles. The amount of entanglement and magic produced is encoded in the S-…
Preparing thermal states of frustrated quantum spin systems using 139 qubits
Roland C. Farrell, Yongtao Zhan, Lucas Katschke +3
Finite-temperature properties of strongly correlated quantum matter are central to condensed matter, chemistry, and high-energy physics, yet are often inaccessible to classical met…

Lucas Katschke, Roland C. Farrell, Umberto Borla +2
Mapping finite-temperature dynamical phase diagrams of quantum many-body models is a necessary step towards establishing a framework of far-from-equilibrium quantum many-body unive…
Studying energy-resolved transport with wavepacket dynamics on quantum computers
Melody Lee, Roland C. Farrell
Probing energy-dependent transport in quantum simulators requires preparing states with tunable energy and small energy variance. Existing approaches often study quench dynamics of…

Digital quantum simulations of scattering in quantum field theories using W states
Roland C. Farrell, Nikita A. Zemlevskiy, Marc Illa +1
High-energy particle collisions can convert energy into matter through the inelastic production of new particles. Quantum computers are an ideal platform for simulating the out-of-…
High Energy Physics from Low Energy Physics
Roland C. Farrell
The separation between physics at low and high energies is essential for physics to have any utility; the details of quantum gravity are not necessary to calculate the trajectory o…
