Persistent State Method for Resonances on Classical and Quantum Computers
Cong-Wu Wang, Lukas Bovermann, Evgeny Epelbaum +4
We introduce a new method for extracting resonance pole positions that does not require non-Hermitian extensions of a Hamiltonian. The complex resonance poles are extracted from un…
Ab initio - scattering with high-fidelity chiral interactions
Avik Sarkar, Serdar Elhatisari, Timo A. Lähde +1
Low-energy - scattering underlies stellar helium burning and sharply tests nuclear forces in the reaction regime. We present its first calculation using the high-fidelity N3L…
Floating block method for quantum Monte Carlo simulations
Avik Sarkar, Dean Lee, Ulf-G. Meißner
Quantum Monte Carlo simulations are powerful and versatile tools for the quantum many-body problem. In addition to the usual calculations of energies and eigenstate observables, qu…
Self-learning Emulators and Eigenvector Continuation
Avik Sarkar, Dean Lee
Emulators that can bypass computationally expensive scientific calculations with high accuracy and speed can enable new studies of fundamental science as well as more potential app…
Convergence of Eigenvector Continuation
Avik Sarkar, Dean Lee
Eigenvector continuation is a computational method that finds the extremal eigenvalues and eigenvectors of a Hamiltonian matrix with one or more control parameters. It does this by…
Projected Cooling Algorithm for Quantum Computation
Dean Lee, Joey Bonitati, Gabriel Given +6
In the current era of noisy quantum devices, there is a need for quantum algorithms that are efficient and robust against noise. Towards this end, we introduce the projected coolin…
Time fractals and discrete scale invariance with trapped ions
Dean Lee, Jacob Watkins, Dillon Frame +5
We show that a one-dimensional chain of trapped ions can be engineered to produce a quantum mechanical system with discrete scale invariance and fractal-like time dependence. By di…
