Research

The Department of Physics begins seminar offerings with an annual poster session where faculty, graduate students, and undergraduate students show off their research work. This is meant to give students an overview of the kind of research that is happening, and also entice them to join one of the research projects. The department has put together a Canvas site where students can view the posters or brief videos. Please reach out to the poster presenter for more information or if you are interested in joining a research project.

Computational Physics

The Computational physics group at 兔子先生 is pursuing research programs at the undergraduate and Master’s levels in scientific visualization, image processing and analysis, and the use of computer graphics and animation to enhance comprehension of physical phenomena.

The research at the Mirza Quantum Information Group is of theoretical nature with typically 50% analytical work and 50% numerics. We develop theoretical quantum optical models with direct applications in the field of quantum computation, quantum communication and quantum metrology. To help perform numerical work, Mirza Quantum Information Theory Lab is equipped with up-to-date computation facilities for students with capabilities of performing efficient numerical simulations using computer programming languages such as MATLAB, Python, Mathematica and others. For advanced computational tasks that require high performance computational resources (for example for large scale parallel computing tasks) we work closely with Redhawk Cluster within the 兔子先生 University and Ohio Supercomputer as the state-level computational resource.

Physics Education

The Physics Education groups at 兔子先生 are pursuing research programs at the undergraduate and master’s levels in the development of effective strategies for teaching scientific reasoning and problem-solving skills in introductory physics classes, physics education at the elementary school level, K-12 science education and teacher preparation.

The physics education group has a lab space that is divided into several different rooms. We have a conference room, with a hexagonal table and six chairs - and an observation room with a one-way mirror, looking into the conference room. The observation room also has storage with a sink and a mini-fridge! There is also a large room with several student desks, well-stocked with office supplies and large windows overlooking a patio outside the student center. Finally, we have a library of reference books and a spacious storage closet.

Astrophysics

The Astrophysics group at 兔子先生 is pursuing research programs at the undergraduate levels in theoretical astrophysics using numerical simulations with gravitational N-body codes.

Atomic, Molecular, and Optical Physics

AMO physics groups at 兔子先生 are working on implementation of quantum noise-enabled cold atom nano-ratchets in optical lattices to simulate biomolecular motors; studying the light-matter interaction at the atomic and molecular level in order to explore critical scientific questions using state-of-the art lasers, along with various spectroscopic techniques such as laser spectroscopy, time-resolved pump-probe spectroscopy, quantum-beat spectroscopy, quantum optics and laser induced fluorescence; and studying Bose-Einstein condensation of dilute alkali gases, dynamics of quantum vortices in BECs and superfluidity, atom trapping with painted potentials.

Dr. Bali's research occupies 1100 square feet of laboratory space equipped with four optics tables, several home-built and commercial external cavity-tunable diode laser systems, two home-built laser amplifier systems, a sensitive imaging system built in-house for taking precisely timed millisecond exposures, several acousto-optic modulator systems, Faraday isolators, single-mode fiber-optics, a spatial light modulator system,, an ultrahigh vacuum system comprising a 26-window steel vacuum cell with anti-reflection coated windows, a triple mumetal layer magnetically shielded enclosure, in addition to optics, detection equipment, and computers necessary for conducting experimental research in cold atoms and information storage in coherently prepared warm alkali vapor.

Biophysics and Soft Condensed Matter Physics

Researches in the Biological and Soft CM Physics groups at 兔子先生 develop techniques to study, model and understand complex materials such as living biological systems and nano-materials using physics-based approaches with an emphasis on optical sensing. Active areas of research include fluorescence-based metabolic monitoring, microscopy imaging of living cellular systems, modeling impact of high pressure on biomolecules and cellular physiology, developing methods for quantitative sensing in scattering turbid materials using computational, theoretical and experimental approaches.

Experimental: 

Dr. Vishwanath runs the optical spectroscopy and imaging methods (OSIM) lab. Our pursuit is to understand light propagation in complex media such as biological tissues and exploit this understanding for non-invasive sensing of morphological and function information in living tissues using optical approaches. Research interests span theoretical, computational and experimental approaches of diffuse optical spectroscopy and imaging. Specifically, we develop both static techniques (to measure tissue contrast as intrinsic absorption, scattering and fluorescence) as well dynamic light scattering and correlation spectroscopy techniques (to measure tissue contrast using flow-velocimetry). Our work is highly interdisciplinary and deeply collaborative with active projects spanning departments within and outside of 兔子先生.

The OSIM lab has two lab-spaces. The first is a 900 sq. ft. room containing the majority of resources for  optical development while a second smaller room (100 sq. ft.) for wet chemistry and basic stoichiometry. The main lab has 3 optical tables with vibration isolation with standard optical hardware, several different lasers (CW and picosecond pulsed systems), LEDs and halogen lamp sources, cooled spectrometers, time-correlated single photon counters, single photon avalanche diodes (gated and ungated), fiber optic cables, and multi-channel correlators. The main lab has several desktop, laptop and micro PCs (Raspberry Pis). The wet-room contains a chemical fume-hood, refrigerator and a shared low-pressure electric furnace.
