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 - defined…
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…
The effect of Coulomb assisted hopping on STM signal: extended two site Hubbard model analysis
Garry Goldstein
In this work we study STM signal in the presence of Coulomb assisted hopping. We perform an extended two site Hubbard model analysis between the atom on the tip and the atom in the…
Time reversal invariant topological 1D and 2D superconductors: doubling the Sau-Luchtin-Tewari-Sarma and Oreg-Refael-von Oppen proposals
Garry Goldstein
In this work we present a doubled version of the Sau-Luchtin-Tewari-Sarma and Oreg-Refael-von Open proposals thereby obtaining time reversal invariant p-wave superconductivity in b…
Four center integrals for Coulomb interactions in small molecules
Garry Goldstein
In this work we make some progress on studying four center integrals for the Coulomb energy for both Hartree Fock (HF) and Density Functional Theory (DFT) calculations for small mo…
Order parameters in quasi-1D spin systems
Garry Goldstein
In this work we extend the notion of what is meant by a meanfield. Meanfields are approximately maps - through some self consistency relation - of a complex, usually manybody, prob…
The Wilson-Fisher Fixed point revisited: importance of the form of the cutoff
Garry Goldstein
In this work we re-examine the Wilson Fisher fixed point. We study Wilsonian momentum space renormalization group (RG) flow for various forms of the cutoff. We show that already at…
Linearized analysis of dissipative Two Axis Counter Twisting (TACT) squeezing for Metrology
Garry Goldstein
In this work we analyze two axis twisting in the presence of depolarizing channel dissipation. We find that spin squeezing is only possible if the dissipation is parametrically wea…
One Axis Twisting (OAT) spin squeezing for metrology
Garry Goldstein
In this work we study One Axis Twisting (OAT) spin squeezing for metrology in the presence of decoherence. We study Linbladian evolution in the presence of both T_1 and T_2 (longit…
Higher Derivative Muffin Tin Orbitals (HDMTO) and Higher Derivative Koringa Khon and Rostoker (HDKKR) methods
Garry Goldstein
In this work we introduce a Linearized version of the Koringa Khon and Rostoker method (LKKR) and show it to be equivalent to the Linearized Muffin Tin Orbitals method (LMTO). We t…
Classical action for the height within the Kardar-Parisi-Zhang (KPZ) equation for surface growth
Garry Goldstein
In this work we write down a classical (not quantum) action for the surface height for the Kardar-Parisi-Zhang (KPZ) equation for surface growth. We do so starting with the regular…
Quench between a Mott insulator and a Lieb-Liniger liquid
G. Goldstein, N. Andrei
In this work we study a quench between a Mott insulator and a repulsive Lieb-Liniger liquid. We find explicitly the stationary state when a long time has passed after the quench. I…
Environment Assisted Precision Measurement
G. Goldstein, P. Cappellaro, J. R. Maze +4
We describe a method to enhance the sensitivity of precision measurements that takes advantage of a quantum sensor's environment to amplify its response to weak external perturbati…
