Simulations of Argon Plasma Decay in a Thermionic Converter
R. E. Groenewald, S. Clark, A. Kannan +1
The dynamics of an argon plasma in the gap of a thermionic diode is investigated using particle-in-cell (PIC) simulations. The time-averaged diode current, as a function of the rel…
Optimizing surface defects for atomic-scale electronics: Si dangling bonds
Peter Scherpelz, Giulia Galli
Surface defects created and probed with scanning tunneling microscopes are a promising platform for atomic-scale electronics and quantum information technology applications. Using…
Floquet-Band Engineering of Shaken Bosonic Condensates
Brandon M. Anderson, Logan W. Clark, Jennifer Crawford +6
Optical control and manipulation of cold atoms has become an important topic in condensed matter. Widely employed are optical lattice shaking experiments which allow the introducti…
Exact correlation functions in the cuprate pseudogap phase: combined effects of charge order and pairing
Rufus Boyack, Chien-Te Wu, Peter Scherpelz +1
There is a multiplicity of charge ordered, pairing-based or pair density wave theories of the cuprate pseudogap, albeit arising from different microscopic mechanisms. For mean fiel…
Perturbation-induced defects in trapped superfluids exhibit generic behavior
Peter Scherpelz, Karmela Padavić, Andy Murray +3
We investigate equilibration processes shortly after sudden perturbations are applied to ultracold trapped superfluids. We show the similarity of phase imprinting and localized den…
Unified treatment of Fermi pockets and arcs scenarios for the cuprates: Sum rule consistent response functions of the pseudogap
Peter Scherpelz, Adam Rançon, Yan He +1
Essential to understanding the cuprate pseudogap phase is a study of the charge (and spin) response functions, which we address here via a consistent approach to the Fermi arcs and…
Phase Imprinting in Equilibrating Fermi Gases: The Transience of Vortex Rings and Other Defects
Peter Scherpelz, Karmela Padavić, Adam Rançon +3
We present numerical simulations of phase imprinting experiments in ultracold trapped Fermi gases which are in good agreement with recent, independent experimental results. Our foc…
Quantum oscillations in non-Fermi liquids: Implications for high-temperature superconductors
Peter Scherpelz, Yan He, K. Levin
We address quantum oscillation experiments in high Tc superconductors and the evidence from these experiments for a pseudogap versus a Fermi liquid phase at high magnetic fields. A…
Theory of Fluctuating Charge Ordering in the Pseudogap Phase of the Cuprates Via A Preformed Pair Approach
Yan He, Peter Scherpelz, K. Levin
We study the static and dynamic behavior of charge ordering within a d-wave pair pseudogap (pg) scenario. This is addressed using a density-density correlation function derived fro…
Pseudogap Effects of Fermi Gases in the Presence of A Strong Effective Magnetic Field
Peter Scherpelz, Dan Wulin, K. Levin +1
We address the important question of how to characterize the normal state of fermionic superfluids under the influence of a strong effective magnetic field, implemented through rap…
General pairing theory for condensed and non-condensed pairs of a superconductor in a high magnetic field
Peter Scherpelz, Dan Wulin, Břetislav Šopík +2
We extend Gor'kov theory to address superconducting pairing at high magnetic fields and general temperatures with arbitrary attractive interaction strength. This analysis begins wi…
