Failure of the Quench Action Formalism for Mott Insulator Initial States
Garry Goldstein
The quench action formalism relies on the assumption that the overlap between a generic initial state and an eigenstate of an integrable model - define…
A Systematic Convergent Sequence of Approximations (of Integral Equation Form) to the Solutions of the Hedin Equations
Garry Goldstein
In many ways the solution to the Hedin equations represents an exact solution to the many body problem. However, for most systems of practical interest, the solution to the Hedin e…
Spin Squeezing of Macroscopic Nuclear Spin Ensembles
Eric Boyers, Garry Goldstein, Alexander O. Sushkov
Spin squeezing has been explored in atomic systems as a tool for quantum sensing, improving experimental sensitivity beyond the spin standard quantum limit for certain measurements…
Kondo Impurities at a Finite Concentration of Impurities
Garry Goldstein
In this work we study the Kondo impurity problem - at a finite concentration of impurities. We identify two parameter regimes for the Kondo impurity problem. 1) The single impurity…
