Quantum Complexity in Nuclear Scattering and Fission Dynamics
Saurabh V. Kadam, Antonio Bjelčić, Nicolas Schunck +1
Quantum computers promise advantages for simulating strongly correlated quantum many-body systems, like atomic nuclei, that are beyond the reach of classical computers. Realizing t…
String-breaking statics and dynamics in a (1+1)D SU(2) lattice gauge theory
Navya Gupta, Emil Mathew, Saurabh V. Kadam +5
String breaking is at the core of hadronization models of relevance to particle colliders. Yet, studies of string-breaking dynamics rooted in quantum chromodynamics remain fundamen…
Loop-string-hadron approach to SU(3) lattice Yang-Mills theory, II: Operator representation for the trivalent vertex
Saurabh V. Kadam, Aahiri Naskar, Indrakshi Raychowdhury +1
This work is the second installment of a series on the loop-string-hadron (LSH) approach to SU(3) lattice Yang-Mills theory. Here, we present the infinite-dimensional matrix repres…
Observation of quantum-field-theory dynamics on a spin-phonon quantum computer
Anton T. Than, Saurabh V. Kadam, Vinay Vikramaditya +5
Simulating out-of-equilibrium dynamics of quantum field theories in nature is challenging with classical methods, but is a promising application for quantum computers. Unfortunatel…
Eigenstate Thermalization in 1+1-Dimensional SU(2) Lattice Gauge Theory Coupled with Dynamical Fermions
Diptarka Das, Lukas Ebner, Saurabh V. Kadam +3
We test the eigenstate thermalization hypothesis (ETH) in 1+1-dimensional SU(2) lattice gauge theory (LGT) with one flavor of dynamical fermions. Using the loop-string-hadron frame…
Quantum computation of hadron scattering in a lattice gauge theory

We present a digital quantum computation of two-hadron scattering in a lattice gauge theory in 1+1 dimensions. We prepare well-separated single-particle wave packets with des…
Tensor-network toolbox for probing dynamics of non-Abelian gauge theories
Emil Mathew, Navya Gupta, Saurabh V. Kadam +4
Tensor-network methods enable probing dynamics of strongly interacting quantum many-body systems, including gauge theories, via Hamiltonian simulation, hence bypassing sign problem…
Loop-string-hadron approach to SU(3) lattice Yang-Mills theory: I. Hilbert space of a trivalent vertex
Saurabh V. Kadam, Aahiri Naskar, Indrakshi Raychowdhury +1
The construction of gauge invariant states of SU(3) lattice gauge theories has garnered new interest in recent years, but implementing them is complicated by the need for SU(3) Cle…
Scattering wave packets of hadrons in gauge theories: Preparation on a quantum computer
Zohreh Davoudi, Chung-Chun Hsieh, Saurabh V. Kadam
Quantum simulation holds promise of enabling a complete description of high-energy scattering processes rooted in gauge theories of the Standard Model. A first step in such simulat…
Theoretical Developments in Lattice Gauge Theory for Applications in Double-beta Decay Processes and Quantum Simulation
Saurabh V. Kadam
Double beta decays are rare nuclear processes that can occur in two modes: two-neutrino double beta decay, observed in the Standard Model, and neutrinoless double beta decay, a hyp…
