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…
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…
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…
Atomic-Scale Visualization of a Cascade of Magnetic Orders in the Layered Antiferromagnet
Arjun Raghavan, Marisa Romanelli, Julian May-Mann +8
is a layered antiferromagnet which has attracted attention due to its exceptionally high mobility, distinctive unidirectional incommensurate charge density wave (CDW), s…
Spin-selective tunneling from nanowires of the candidate topological Kondo insulator SmB6
Anuva Aishwarya, Zhuozhen Cai, Arjun Raghavan +9
Incorporating relativistic physics into quantum tunneling can lead to exotic behavior such as perfect transmission via Klein tunneling. Here, we probe the tunneling properties of s…
Magnetic-field sensitive charge density wave orders in the superconducting phase of UTe2
Anuva Aishwarya, Julian May-Mann, Arjun Raghavan +8
The intense interest in triplet superconductivity partly stems from theoretical predictions of exotic excitations such as non-abelian Majorana modes, chiral supercurrents, and half…
Observation of a Smoothly Tunable Dirac Point in
Sean Howard, Arjun Raghavan, Davide Iaia +9
State-of-the-art topological devices require the use topological surface states to drive electronic transport. In this study, we examine a tunable topological system, $Ge(Bi_{x}Sb_…
Inter-adsorbate forces and coherent scattering in helium spin-echo experiments
David J. Ward, Arjun Raghavan, Anton Tamtögl +5
In studies of dynamical systems, helium atoms scatter coherently from an ensemble of adsorbates as they diffuse on the surface. The results give information on the co-operative beh…
