Emergent mode and bound states in single-component one-dimensional lattice fermionic systems
Yuchi He, Binbin Tian, David Pekker +1
We study the formation of bound states in a one-dimensional, single-component Fermi chain with attractive interactions. The phase diagram, computed from DMRG (density matrix renorm…
Reconfigurable edge-state engineering in graphene using LaAlO/SrTiO nanostructures
Jianan Li, Qing Guo, Lu Chen +9
The properties of graphene depend sensitively on doping with respect to the charge-neutrality point (CNP). Tuning the CNP usually requires electrical gating or chemical doping. Her…
Excitation of two-photon photoemission where epsilon is near zero on Ag(111)
Marcel Reutzel, Andi Li, Branko Gumhalter +1
Because silver has epsilon-near-zero (ENZ) in the near-UV spectral region, its optical response is expected to be dominantly plasmonic and nonperturbatively nonlinear. The ENZ prop…
Ultrafast asymmetric Rosen-Zener-like coherent phonon responses observed in silicon
Yohei Watanabe, Ken-ichi Hino, Nobuya Maeshima +2
We investigate the spectral profiles of time signals attributed to coherent phonon generation in an undoped Si crystal. Here, the retarded longitudinal-optical (LO) phonon Green fu…
Coherent two-dimensional multiphoton photoelectron spectroscopy of metal surfaces
Marcel Reutzel, Andi Li, Hrvoje Petek
Light interacting with metals elicits an ultrafast coherent many-body screening response on sub- to few-femtosecond time-scales, which makes its experimental observation challengin…
A Simple game simulating quantum measurements of qubits
Theodore A. Corcovilos
Games are useful tools for introducing new concepts to students. This paper describes a competitive two-player game for sophomore students in a modern physics survey course or juni…
