Wavefunction matching for solving quantum many-body problems
Serdar Elhatisari, Lukas Bovermann, Yuanzhuo Ma +15
Ab initio calculations play an essential role in our fundamental understanding of quantum many-body systems across many subfields, from strongly correlated fermions to quantum chem…
Impurity Lattice Monte Carlo for Hypernuclei
Dillon Frame, Timo A. Lähde, Dean Lee +1
We consider the problem of including hyperons into the ab initio framework of nuclear lattice effective field theory. In order to avoid large sign oscillations in Monte Carlo s…
Ab Initio Simulations of Light Nuclear Systems Using Eigenvector Continuation and Auxiliary Field Monte Carlo
Dillon K. Frame
In this work, we discuss a new method for calculation of extremal eigenvectors and eigenvalues in systems or regions of parameter space where direct calculation is problematic. Thi…
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…
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…
