Dynamic competition between phason and amplitudon observed by ultrafast multimodal scanning tunneling microscopy
Seokjin Bae, Arjun Raghavan, Soyeun Kim +7
The intertwining between two ordered states that arise from the same interactions is reflected in the dynamics of their coupled collective excitations. While the equilibrium phase…
Microscopic evidence of dominant excitonic instability in Ta2NiSe5
Seokjin Bae, Arjun Raghavan, Irena Feldman +2
An excitonic insulator (EI) is a charge-neutral bosonic condensate of spontaneously formed electron-hole pairs. Exotic quantum phenomena such as dissipationless charge neutral tran…
Reply to "Limitations of detecting structural changes and time-reversal symmetry breaking in scanning tunneling microscopy experiments"
Yuqing Xing, Seokjin Bae, Stephen D. Wilson +3
In their comment, the authors attribute our observations of light- and magnetic-field-induced manipulation of the CDW state in RbV3Sb5 to random experimental artifacts such as tip…
Atomic-scale imaging and charge state manipulation of NV centers by scanning tunneling microscopy
Arjun Raghavan, Seokjin Bae, Nazar Delegan +2
Nitrogen-vacancy (NV) centers in diamond are among the most promising solid-state qubit candidates, owing to their exceptionally long spin coherence times, efficient spin-photon co…
