Temperature Dependent Non-linear Damping in Palladium Nano-mechanical Resonators
Shelender Kumar, S. Rebari, Satyendra P. Pal +5
Advances in nano-fabrication techniques has made it feasible to observe damping phenomena beyond the linear regime in nano-mechanical systems. In this work, we report cubic non-lin…
Engineering Surface Oxygen Vacancies in to Form a High Mobility and Transparent Quasi Two dimensional Electron System
Shyam Sundar Yadav, Shelender Kumar, Pankaj Kumar +1
Quasi-two-dimensional electron systems (q-2DES) are formed in various hetero-structures, including oxide interfaces. Oxygen vacancies (OVs) in oxides like are kn…
Observation of transient superconductivity at the LaAlO/SrTiO interface
Gopi Nath Daptary, Shelender Kumar, Pramod Kumar +6
We report the observation of a magnetic field assisted transient superconducting state in the two dimensional electron gas existing at the interface of LaAlO/SrTiO heterost…
Correlated Non-Gaussian phase fluctuations in LaAlO/SrTiO heterointerface
Gopi Nath Daptary, Shelender Kumar, Pramod Kumar +4
We probe the existence of large correlated non-Gaussian phase fluctuations in the vicinity of the superconducting phase transition in the conducting layer residing at the interface…
Suppression of measurement-induced state transitions in cosÏ-coupling transmon readout
Cyril Mori, Francesca D Esposito, Alexandru Petrescu +12
Drive-induced unwanted state transitions (DUST) are limiting both for microwave readout and parametric operations of superconducting qubits. Among them, measurement-induced state t…
Low temperature dissipation scenarios in palladium nano-mechanical resonators
S. Rebari, Shelender Kumar, S. Indrajeet +4
We study dissipation in Pd nano-mechanical resonators at low temperatures in the linear response regime. Metallic resonators have shown characteristic features of dissipation due t…
