Statistical Mechanics of Heteropolymers from Lattice Gauge Theory
Veronica Panizza, Alessandro Roggero, Philipp Hauke +1
Lattice models are valuable tools to gain insight into the statistical physics of heteropolymers. We rigorously map the partition function of these models into a vacuum expectation…
Phase-Space methods for neutrino oscillations: extension to multi-beams
Denis Lacroix, Angel Bauge, Bulent Yilmaz +3
The Phase-Space approach (PSA), which was originally introduced in [Lacroix et al., Phys. Rev. D 106, 123006 (2022)] to describe neutrino flavor oscillations for interacting neutri…
Spin response of neutron matter in ab initio approach
J. E. Sobczyk, W. Jiang, A. Roggero
We propose a general method embedded in the ab initio nuclear framework to reconstruct linear response functions and calculate sum rules. Within our approach, based on the Gaussian…
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…
Evaluation of phase shifts for non-relativistic elastic scattering using quantum computers
Francesco Turro, Kyle A. Wendt, Sofia Quaglioni +2
Simulations of scattering processes are essential in understanding the physics of our universe. Computing relevant scattering quantities from ab initio methods is extremely difficu…
Scattering Neutrinos, Spin Models, and Permutations
Duff Neill, Hanqing Liu, Joshua Martin +1
We consider a class of Heisenberg all-to-all coupled spin models inspired by neutrino interactions in a supernova with degrees of freedom. These models are characterized by a c…
Solving the homogeneous Bethe-Salpeter equation with a quantum annealer
Filippo Fornetti, Alex Gnech, Tobias Frederico +6
The homogeneous Bethe-Salpeter equation (hBSE), describing a bound system in a genuinely relativistic quantum-field theory framework, was solved for the first time by using a D-Wav…
Fault-tolerant simulation of Lattice Gauge Theories with gauge covariant codes
L. Spagnoli, A. Roggero, N. Wiebe
We show in this paper that a strong and easy connection exists between quantum error correction and Lattice Gauge Theories (LGT) by using the Gauge symmetry to construct an efficie…
Early Fault-Tolerant Quantum Algorithms in Practice: Application to Ground-State Energy Estimation
Oriel Kiss, Utkarsh Azad, Borja Requena +3
We investigate the feasibility of early fault-tolerant quantum algorithms focusing on ground-state energy estimation problems. In particular, we examine the computation of the cumu…
Quantum error mitigation for Fourier moment computation
Oriel Kiss, Michele Grossi, Alessandro Roggero
Hamiltonian moments in Fourier space - expectation values of the unitary evolution operator under a Hamiltonian at different times - provide a convenient framework to understand qu…
