Di-nucleons do not form bound states at heavy pion mass
John Bulava, M. A. Clark, Arjun S. Gambhir +16
We perform a high-statistics lattice QCD calculation of the low-energy two-nucleon scattering amplitudes. In order to address discrepancies in the literature, the calculation is pe…
Adiabatic Quantum Computation with the Fermionic Position Space Schrödinger Equation
Kenneth S. McElvain
The efficient encoding of the fermionic Schrödinger equation as a spin system Hamiltonian is a long-term problem. I describe an encoding for the fermionic position space Schrödinge…
Nuclear-level Effective Theory of Conversion: Formalism and Applications
W. C. Haxton, Evan Rule, Ken McElvain +1
New mu-to-e conversion searches aim to advance limits on charged lepton flavor violation (CLFV) by four orders of magnitude. By considering P and CP selection rules and the structu…
Gate Based Implementation of the Laplacian with BRGC Code for Universal Quantum Computers
Ermal Rrapaj, Kenneth S. McElvain, Chia Cheng Chang +2
We study the gate-based implementation of the binary reflected Gray code (BRGC) and binary code of the unitary time evolution operator due to the Laplacian discretized on a lattice…
Nuclear-Level Effective Theory of Conversion
Evan Rule, W. C. Haxton, Ken McElvain
The Mu2e and COMET conversion experiments are expected to significantly advance limits on new sources of charged lepton flavor violation (CLFV). Almost all theoret…
Improving Schrödinger Equation Implementations with Gray Code for Adiabatic Quantum Computers
Chia Cheng Chang, Kenneth S. McElvain, Ermal Rrapaj +1
We reformulate the continuous space Schrödinger equation in terms of spin Hamiltonians. For the kinetic energy operator, the critical concept facilitating the reduction in model co…
Towards grounding nuclear physics in QCD
Christian Drischler, Wick Haxton, Kenneth McElvain +4
Exascale computing could soon enable a predictive theory of nuclear structure and reactions rooted in the Standard Model, with quantifiable and systematically improvable uncertaint…
Progress in Multibaryon Spectroscopy
Evan Berkowitz, David Brantley, Kenneth McElvain +9
Anchoring the nuclear interaction in QCD is a long-outstanding problem in nuclear physics. While the lattice community has made enormous progress in mesonic physics and single nucl…
Nuclear Physics without High-Momentum Potentials: Constructing the Nuclear Effective Interaction Directly from Scattering Observables
K. S. McElvain, W. C. Haxton
The traditional approach to nuclear physics encodes phase shift information in a nucleon-nucleon (NN) potential, producing a nucleon-level interaction that captures the sub-GeV con…
Simulating the weak death of the neutron in a femtoscale universe with near-Exascale computing
Evan Berkowitz, M. A. Clark, Arjun Gambhir +9
The fundamental particle theory called Quantum Chromodynamics (QCD) dictates everything about protons and neutrons, from their intrinsic properties to interactions that bind them i…
BIGSTICK: A flexible configuration-interaction shell-model code (updated)
Calvin W. Johnson, W. Erich Ormand, Kenneth S. McElvain +2
We present BIGSTICK, a flexible configuration-interaction open-source shell-model code for the many-fermion problem. Written mostly in Fortran 90 with some later extensions, BIGSTI…
Job Management and Task Bundling
Evan Berkowitz, Gustav R. Jansen, Kenneth McElvain +1
High Performance Computing is often performed on scarce and shared computing resources. To ensure computers are used to their full capacity, administrators often incentivize large…
Nuclear Physics without High-Momentum Potentials: Direct Construction of the Effective Interaction from Scattering Observables
Kenneth S. McElvain, W. C. Haxton
The standard approach to nuclear physics encodes phase shift information in an NN potential, then decodes that information in forming an effective interaction, appropriate to a low…
