Restricted Boltzmann Machines Propagators for Auxiliary Field Diffusion Monte Carlo
Jordan M. R. Fox, Alessandro Lovato, Alessandro Roggero +1
The auxiliary field diffusion Monte Carlo method uses imaginary-time projection techniques to accurately solve the ground-state wave function of atomic nuclei and infinite nuclear…
Chiral EFT calculation of neutrino reactions in warm neutron-rich matter
Eunkyoung Shin, Ermal Rrapaj, Jeremy W. Holt +1
Neutrino scattering and absorption rates of relevance to supernovae and neutron star mergers are obtained from nuclear matter dynamical structure functions that encode many-body ef…
Quantum information and quantum simulation of neutrino physics
A. B. Balantekin, Michael J. Cervia, Amol V. Patwardhan +2
In extreme astrophysical environments such as core-collapse supernovae and binary neutron star mergers, neutrinos play a major role in driving various dynamical and microphysical p…
Exact representations of many body interactions with RBM neural networks
Ermal Rrapaj, Alessandro Roggero
Restricted Boltzmann Machines (RBM) are simple statistical models defined on a bipartite graph which have been successfully used in studying more complicated many-body systems, bot…
Is Hyperon Polarization in Relativistic Heavy Ion Collisions Connected to Axial U(1) Symmetry Breaking at High Temperature?
Joseph I. Kapusta, Ermal Rrapaj, Serge Rudaz
Experiments at the Relativistic Heavy Ion Collider (RHIC) have measured the net polarization of and hyperons and attributed it to a coupling between their spin and the…
Relaxation Time for Strange Quark Spin in Rotating Quark-Gluon Plasma
Joseph I. Kapusta, Ermal Rrapaj, Serge Rudaz
Experiments at the Relativistic Heavy Ion Collider (RHIC) have measured the net polarization of and hyperons and attributed it to a coupling between their spin and the…
Symmetry Restoration in Mixed-Spin Paired Heavy Nuclei
Ermal Rrapaj, A. O. Macchiavelli, Alexandros Gezerlis
The nature of the nuclear pairing condensates in heavy nuclei, specifically neutron-proton (spin-triplet), versus identical-particle (spin-singlet) pairing has been an active area…
Eigenvector continuation with subspace learning
Dillon Frame, Rongzheng He, Ilse Ipsen +3
A common challenge faced in quantum physics is finding the extremal eigenvalues and eigenvectors of a Hamiltonian matrix in a vector space so large that linear algebra operations o…
Nucleon-nucleon bremsstrahlung of dark gauge bosons and revised supernova constraints
Ermal Rrapaj, Sanjay Reddy
We calculate the rate of production of hypothetical light vector bosons (LVBs) from nucleon-nucleon bremsstrahlung reactions in the soft radiation limit directly in terms of the me…
Microscopically constrained mean field models from chiral nuclear thermodynamics
Ermal Rrapaj, Alessandro Roggero, Jeremy W. Holt
We explore the use of mean field models to approximate microscopic nuclear equations of state derived from chiral effective field theory across the densities and temperatures relev…
Electron-neutron scattering and transport properties of neutron stars
Bridget Bertoni, Sanjay Reddy, Ermal Rrapaj
We show that electrons can couple to the neutron excitations in neutron stars and find that this can limit their contribution to the transport properties of dense matter, especiall…
Charged-current reactions in the supernova neutrino-sphere
Ermal Rrapaj, J. W. Holt, Alexander Bartl +2
We calculate neutrino absorption rates due to charged-current reactions and in the outer regions of a newly born neutr…
