Dynamics of entanglement entropy of interacting fermions in a 1D driven harmonic trap

Autor: McKenney, J. R., Porter, W. J., Drut, J. E.

Following up on a recent analysis of two cold atoms in a time-dependent harmonic trap in one dimension, we explore the entanglement entropy of two and three fermions in the same situation when driven through a parametric resonance. We find that the p

Thermodynamics of one-dimensional SU(4) and SU(6) fermions with attractive interactions

Autor: Hoffman, M. D., Loheac, A. C., Porter, W. J., Drut, J. E.

Publikováno v: Phys. Rev. A 95, 033602 (2017)

Motivated by advances in the manipulation and detection of ultracold atoms with multiple internal degrees of freedom, we present a finite-temperature lattice Monte Carlo calculation of the density and pressure equations of state, as well as Tan's con

Ground state of the two-dimensional attractive Fermi gas: essential properties from few- to many-body

Autor: Rammelmüller, L., Porter, W. J., Drut, J. E.

Publikováno v: Phys. Rev. A 93, 033639 (2016)

We calculate the ground-state properties of unpolarized two-dimensional attractive fermions in the range from few to many particles. Using first-principles lattice Monte Carlo methods, we determine the ground-state energy, Tan's contact, momentum dis

Ground-state energy, density profiles, and momentum distribution of attractively interacting 1D Fermi gases with hard-wall boundaries: a Monte Carlo study

Autor: McKenney, J. R., Shill, C. R., Porter, W. J., Drut, J. E.

Publikováno v: J. Phys. B 49, 225001 (2016)

Motivated by the realization of hard-wall boundary conditions in experiments with ultracold atoms, we investigate the ground-state properties of spin-1/2 fermions with attractive interactions in a one-dimensional box. We use lattice Monte Carlo metho

Few-fermion systems in one dimension: Ground- and excited-state energies and contacts

Autor: Rammelmüller, L., Porter, W. J., Loheac, A. C., Drut, J. E.

Publikováno v: Phys. Rev. A 92, 013631 (2015)

Using the lattice Monte Carlo method, we compute the energy and Tan's contact in the ground state as well as the first excited state of few- to many-fermion systems in a one-dimensional periodic box. We focus on unpolarized systems of N=4,6,...,12 pa

Universality in one-dimensional fermions at finite temperature: Density, pressure, compressibility, and contact

Autor: Hoffman, M. D., Javernick, P. D., Loheac, A. C., Porter, W. J., Anderson, E. R., Drut, J. E.

Publikováno v: Phys. Rev. A 91, 033618 (2015)

We present finite-temperature, lattice Monte Carlo calculations of the particle number density, compressibility, pressure, and Tan's contact of an unpolarized system of short-range, attractively interacting spin-1/2 fermions in one spatial dimension,

Microstructure-dependent local strain behavior in polycrystals through in situ scanning electron microscope tensile experiments

Autor: Tschopp, M. A., Bartha, B. B., Porter, W. J., Murray, P. T., Fairchild, S. B.

Publikováno v: Metallurgical Transactions A 40 (2009) 2363-2368

Digital image correlation of laser-ablated platinum nanoparticles on the surface of a polycrystalline metal (nickel-based superalloy Rene 88DT) was used to obtain the local strain behavior from an in situ scanning electron microscope tensile experime
