Acoustic Phonon Dynamics in Co-Doped BaFeAs Thin Film
Alexander Bartenev, Roman Kolodka, Larry Theran +5
Pump-probe reflectivity reveals coherent acoustic oscillations at 33 and 8.2 GHz in a Ba(FeCo)As thin film. The acoustic response was analyzed using a mod…
Fit-Free Optical Determination of Electronic Thermalization Time in Nematic Iron-Based Superconductors
Alexander Bartenev, Roman Kolodka, Ki-Tae Eom +6
We present a nematic response function model (NRFM) for fit-free direct extraction of the characteristic time of ultrafast electronic thermalization in iron-based superconductors,…
Twisted oxide membrane interface by local atomic registry design
Min-Su Kim, Kyoungjun Lee, Ryo Ishikawa +9
Interplay of lattice, orbital, and charge degrees of freedom in complex oxide materials has hosted a plethora of exotic quantum phases and physical properties. Recent advances in s…
Electric and Magnetic Field-dependent Tunneling between Coupled Nanowires
Shashank Anand, Ranjani Ramachandran, Kitae Eom +9
Coupled quasi-one-dimensional (quasi-1D) electron systems host rich emergent physics that cannot be accounted for by understanding isolated 1D electron systems alone. Open question…
Magnetically Tuned Metal-Insulator Transition in LaAlO/SrTiO Nanowire Arrays
Ranjani Ramachandran, Shashank Anand, Kitae Eom +9
A wide family of two dimensional (2D) systems, including stripe-phase superconductors, sliding Luttinger liquids, and anisotropic 2D materials, can be modeled by an array of couple…
Long-Range Nanoelectromechanical Coupling at the LaAlO/SrTiO Interface
Aditi Nethwewala, Kitae Eom, Muqing Yu +4
The LaAlO/SrTiO interface hosts a plethora of gate-tunable electronic phases. Gating of LaAlO/SrTiO interfaces are usually assumed to occur electrostatically. Howev…
