Small models, big threats: Characterizing safety challenges from low-compute AI models
Prateek Puri
Artificial intelligence (AI) systems are revolutionizing fields such as medicine, drug discovery, and materials science; however, many technologists and policymakers are also conce…
Development and Benchmarking of a Blended Human-AI Qualitative Research Assistant
Joseph Matveyenko, James Liu, John David Parsons +3
Qualitative research emphasizes constructing meaning through iterative engagement with textual data. Traditionally this human-driven process requires navigating coder fatigue and i…
Digital cloning of online social networks for language-sensitive agent-based modeling of misinformation spread
Prateek Puri, Gabriel Hassler, Anton Shenk +1
We develop a simulation framework for studying misinformation spread within online social networks that blends agent-based modeling and natural language processing techniques. Whil…
Reaction blockading in charged-neutral excited-state chemistry at low collision energy
Prateek Puri, Michael Mills, Ionel Simbotin +5
We study an excited atom-polar molecular ion chemical reaction (Ca + BaCl) at low temperature by utilizing a hybrid atom-ion trapping system. The reaction rate and product…
Excitation-assisted nonadiabatic charge-transfer reaction in a mixed atom-ion system
Ming Li, Michael Mills, Prateek Puri +3
An important physical process unique to neutral-ion systems is the charge-transfer (CT) reaction. Here, we present measurements of and models for CT processes between co-trapped ul…
Engineering excited-state interactions at ultracold temperatures
Michael Mills, Prateek Puri, Ming Li +5
Using a recently developed method for precisely controlling collision energy, we observe a dramatic suppression of inelastic collisions between an atom and ion (Ca + Yb) at low…
High-resolution collision energy control through ion position modulation in atom-ion hybrid systems
Prateek Puri, Michael Mills, Elizabeth P. West +2
We demonstrate an ion shuttling technique for high-resolution control of atom-ion collision energy by translating an ion held within a radio-frequency trap through a magneto-optica…
Synthesis of mixed hypermetallic oxide BaOCa from laser-cooled reagents in an atom-ion hybrid trap
Prateek Puri, Michael Mills, Christian Schneider +5
Hypermetallic alkaline earth (M) oxides of formula MOM have been studied under plasma conditions that preclude insight into their formation mechanism. We present here the applicati…
Improved magneto-optical trapping of Ca
Michael Mills, Prateek Puri, Yanmei Yu +3
We investigate the limiting factors in the standard implementation of the Ca magneto-optical trap. We find that intercombination transitions from the 4s5p 1P1 state used to repump…
Blue-sky bifurcation of ion energies and the limits of neutral-gas sympathetic cooling of trapped ions
Steven J. Schowalter, Alexander J. Dunning, Kuang Chen +3
Sympathetic cooling of trapped ions through collisions with neutral buffer gases is critical to a variety of modern scientific fields, including fundamental chemistry, mass spectro…
Photodissociation spectroscopy of the dysprosium monochloride molecular ion
Alexander Dunning, Alexander Petrov, Steven J. Schowalter +3
We have performed a combined experimental and theoretical study of the photodissociation cross section of the molecular ion DyCl. The photodissociation cross section for the ph…
Action spectroscopy of SrCl using an integrated ion trap time-of-flight mass spectrometer
Prateek Puri, Steven J. Schowalter, Svetlana Kotochigova +2
The photodissociation cross-section of SrCl is measured in the spectral range of 36000 -- 46000 cm using a modular time-of-flight mass spectrometer (TOF-MS). By irradiat…
