Radio-Frequency-Driven Reshaping of the Mesoscale Charge-Density-Wave Landscape in 1T-TaS2 Thin-Film Devices
Maedeh Taheri, Zahra Ebrahim Nataj, Nick Sesing +4
Radio-frequency excitation directly reshapes the mesoscale charge-density-wave landscape in quasi-two-dimensional 1T-TaS2 thin films. Under combined RF and DC bias, the hysteretic…
Phonon Signatures of Near-Room-Temperature Phase Transition in Quasi-One-Dimensional Bi4I4 Topological van der Waals Material
Nidhish Thiruthukkal Puthenveettil, Topojit Debnath, Clayton Mantz +7
The quasi-one-dimensional material Bi4I4 hosts two crystallographically similar polymorphs that realize distinct topological insulating phases separated by a first-order structural…
AC Response Across the Metal Insulator Transition of YBCO Josephson Junctions Fabricated with a Helium Ion Beam
Adhilsha Parachikunnumal, Nirjhar Sarkar, Aravind Rajeev Sreeja +5
Using focused helium ion beam (FHIB) irradiation, we fabricated in-plane, high-Tc YBCO Josephson junctions. By varying the dose of the irradiation, we tune the junction barriers fr…
A Quieter State of Charge -- Ultra-Low-Noise Collective Current in Charge-Density-Wave Nanowires
Subhajit Ghosh, Nicholas Sesing, Tina Salguero +3
Electronic flicker noise limits phase stability in communication systems, reduces the sensitivity and selectivity of sensors, and degrades coherence in quantum devices. There is a…
Quantum Spin Singlet and Classical Néel-Ordered Ground States in MoX3 (X = I, Br) Spin-3/2 Dimerized Antiferromagnetic Chain Crystals
Jordan Teeter, Topojit Debnath, Harshil Goyal +8
We report that MoX3 (X = I, Br) are rare van der Waals materials that exhibit signatures of both quantum spin chains with a spin singlet ground state and classical Neel order. Bulk…
Giant Gate Response of the Charge in an Electron-Lattice Condensate
Maedeh Taheri, Jordan Teeter, Topojit Debnath +4
Efficient electrical capacitive control is important for the next generation of ultra-low-power and ultra-fast electronics and energy-storage devices. Correlated electronic phases…
