Chirality manipulation of ultrafast phase switchings in a correlated CDW-Weyl semimetal

Bing Cheng, Di Cheng, Tao Jiang +8

A recently emerging concept for quantum phase discovery is the controlled gapping of linear band crossings in topological semimetals. For example, achieving topological superconduc…

Visualizing heterogeneous dipole fields by terahertz light coupling in individual nano-junctions used in transmon qubits

R. H. J. Kim, J. M. Park, S. Haeuser +12

The fundamental challenge underlying superconducting quantum computing is to characterize heterogeneity and disorder in the underlying quantum circuits. These nonuniform distributi…

Ultrafast generation and detection of propagating coherent acoustic phonon wave packets in ultra-thin iron pnictide films

D. Cheng, B. Song, J. H. Kang +9

We observe pronounced oscillations in differential reflectivity of 9 nm and 60 nm BaFe\textsubscript{2}As\textsubscript{2} (Ba-122) thin films using ultrafast optical spectroscopy.…

Local atomic configuration control of superconductivity in the undoped pnictide parent compound BaFe2As2

Jong-Hoon Kang, Philip J. Ryan, Jong-Woo Kim +13

Emergent superconductivity is strongly correlated with the symmetry of local atomic configuration in the parent compounds of iron-based superconductors. While chemical doping or hy…

Light Quantum Control of Persisting Higgs Modes in Iron-Based Superconductors

C. Vaswani, J. H. Kang, M. Mootz +12

The Higgs mechanism, i.e., spontaneous symmetry breaking of the quantum vacuum, is a cross-disciplinary principle, universal for understanding dark energy, antimatter and quantum m…

Coherent Band-Edge Oscillations and Dynamic LO Phonon Mode Splitting as Evidence for Polaronic Coupling in Perovskites

Z. Liu, C. Vaswani, L. Luo +12

The coherence of collective modes, such as phonons, and their modulation of the electronic states are long sought in complex systems, which is a cross-cutting issue in photovoltaic…
