This work presents the demonstration of a superconducting niobium nitride (NbN) nanowire surface acoustic wave transducer, enabling a cryogenic acoustic delay line in scandium alum…
Second-Order Optical Nonlinearity of AlScN Films Grown By Molecular Beam Epitaxy
Joongwon Lee, Thai-Son Nguyen, Len van Deurzen +8
Alloys of AlN have rapidly emerged as a material platform for nonlinear optics. In this paper, we measure the second-order optical nonlinearity of AlScN films grown directly on nit…
Toward Enhanced Inertial Sensing via Dynamically Soft Topological States in Piezoelectric Microacoustic Metamaterials
Onurcan Kaya, Niccolo Scalise Pantuso, Marco Galli +10
In recent decades, microelectromechanical systems (MEMS)-based gyroscopes have been employed to meet positioning and navigation demands of a plethora of commercially available devi…
Characterization of Acoustic Losses in Interdigitated VHF to mmWave Piezoelectric M/NEMS Resonators
Luca Colombo, Gabriel Giribaldi, Ryan Tetro +6
This work reports on a technology-agnostic and frequency-independent methodology combining a-priori modeling, Finite Element Analysis (FEA), and experimental results for the charac…
Parametric Frequency Divider based Ising Machines
Nicolas Casilli, Tahmid Kaisar, Luca Colombo +3
We report on a new class of Ising Machines (IMs) that rely on coupled parametric frequency dividers (PFDs) as macroscopic artificial spins. Unlike the IM counterparts based on subh…
Single-molecule motion control
Divyam Neer Verma, KV Chinmaya, Jan Heck +4
Achieving dynamic manipulation and control of single molecules at high spatio-temporal resolution is pivotal for advancing atomic-scale computing and nanorobotics. However, this en…
Superfluidic nature of self-driven nanofluidics at liquid-gas interfaces
Vinitha Johny, Sonia Contera, Siddharth Ghosh
Self-driven nanofluidic flow at the liquid-air interface is a non-intuitive phenomenon. This flow behaviour was not driven by classical pressure difference or evaporation only. Dep…
Transport of aerosols and nanoparticles through respirators and masks
K. V. Chinmaya, Moumita Ghosh, G Mohan Rao +1
In several countries wearing multiple surgical masks or N95 respirators was mandatory in public during the COVID pandemic. In this study, we investigated the transportation and fil…
Towards real-time oxygen sensing: From nanomaterials to plasma
Vinitha Johny, KV Chinmaya, Muhammed Nihal CV +4
A significantly large scope is available for the scientific and engineering developments of high-throughput ultra-high sensitive oxygen sensors. We give a perspective of oxygen sen…
Active solid-state nanopores: Self-driven flows/chaos at liquid-gas nanofluidic interface
Vinitha Johny, Siddharth Ghosh
We present a study of self-driven flow dynamics at the liquid-gas interface within nanofluidic pores, devoid of any external driving forces. The investigation centres on the Raylei…
Ageing related states of complex network formation in areca nuts
KV Chinmaya, Moumita Ghosh, Siddharth Ghosh
Complex pattern formation is an essential characteristic of plants and their ageing, growth, and evolution. Perception of these patterns is an intrinsic nature of plant-dependent a…
Feynman-Enderlein Path Integral for Single-Molecule Nanofluidics
Siddharth Ghosh
Single-molecule motions in the nanofluidic domain are extremely difficult to characterise because of various complex physical and physicochemical interactions. We present a method…
