Title: Towards quantum computation of nuclear and hadronic scattering

Abstract: Simulating nuclear and hadronic scattering processes requires representing dynamics in very large Hilbert spaces. With the advent of quantum computers, Hamiltonian simulation of dynamical processes has become a reality. In this talk, I will discuss our recent efforts to simulate hadronic scattering on a quantum computer using a wave-packet state preparation algorithm and Trotterized time evolution for a 1+1D Z2 LGT coupled to dynamical matter. We demonstrate the viability of our algorithm for NISQ devices by comparing classical simulations with results obtained on commercially available trapped-ion quantum computers. Finally, I will discuss aspects of quantum complexity for nuclear scattering and their implications for simulating dynamical nuclear scattering using quantum computers.

Title: Evolution of Helicity Property of Relic Neutrinos and Implications

on Their Detection

Abstract: Neutrinos in the early Universe decoupled essentially in helicity eigenstates.

As they propagate through the Universe, their helicities could be modified via

two effects. First, neutrinos with a finite magnetic moment would rotate their

spins with respect to their momenta as they encounter cosmic magnetic fields,

modifying their helicities. Second, the bending of neutrino's spin by a

gravitational field lags the bending of its momentum, again modifying its helicity.

We study both effects and investigate the implications of the

helicity modification on the detection of relic neutrinos using the Inverse

Tritium Beta Decay (ITBD) reaction. We find that the ITBD rate depends

sensitively on the neutrino mass hierarchy and on the Dirac or Majorana nature

of the neutrinos. This talk is based on several papers in collaboration with

Gordon Baym.
