Interpreting pulse-shape effects in pump-probe spectroscopies
A. M. Shvaika, O. P. Matveev, T. P. Devereaux +1
The effect of the pulse-shape on pump-probe spectroscopies is examined for the simplest model of noninteracting fermions on an infinite-dimensional hypercubic lattice. The probe-mo…
Positivity of the spectral densities of retarded Floquet Green functions
Götz S. Uhrig, Mona H. Kalthoff, James K. Freericks
Periodically driven nonequilibrium many-body systems are interesting because they have a quasi-energy spectra, which can be tailored by controlling the external driving fields. We…
Verification of a many-ion simulator of the Dicke model through slow quenches across a phase transition
A. Safavi-Naini, R. J. Lewis-Swan, J. G. Bohnet +7
We use a self-assembled two-dimensional Coulomb crystal of ions in the presence of an external transverse field to engineer a simulator of the Dicke Hamiltonian, an iconi…
Nonequilibrium Electron Dynamics In Pump-Probe Spectroscopy: Role Of Excited Phonon Populations
O. Abdurazakov, D. Nevola, A. Rustagi +3
We study the role of excited phonon populations in the relaxation rates of nonequilibrium electrons using a nonequilibrium Green's function formalism. The transient modifications i…
Calculating spherical harmonics without derivatives
M. Weitzman, J. K. Freericks
The derivation of spherical harmonics is the same in nearly every quantum mechanics textbook and classroom. It is found to be difficult to follow, hard to understand, and challengi…
