My research program is in the field of experimental condensed matter physics with particular focus on the magnetism and electronic properties of materials, using thermodynamic and electrical and thermal transport and Raman/IR spectroscopy. These physical quantities are investigated under extreme conditions such as very low temperature, high DC and pulsed magnetic field, high hydrostatic pressure and sometimes nanoscale spatial dimension. Specific experimental expertise includes thermal transport and thermoelectric phenomena, electrical and thermal conductions particularly in the presence of magnetic ordering and in low dimensional systems near the phase boundary. My group also synthesizes high quality single crystalline semimetals and magnetic compounds.
experimental condensed matter physics, magnetism, spin texture states and their electronics properties, quantum spin liquid, high DC magnetic field measurements, pulsed magnetic field, SQUID magnetometry, cantilever-based magnetometry, shot noise, Johnson noise, thermometry, thermoelectricity, thermal and electrical transport properties measurement under intense magnetic field, magneto-Raman and magneto Infra-red spectroscopy
PHYS 2150 - Experimental Physics 2
One lect., one 2-hour lab per week. Includes many experiments of modern physics, including atomic physics, solid state physics, electron diffraction, radioactivity and quantum effects. Normally taken concurrently with PHYS 2130 or PHYS 2170, this course may be taken after PHYS 2130 or PHYS 2170.
PHYS 3330 - Electronics for the Physical Sciences
Fall 2018 / Spring 2020 / Fall 2021 / Spring 2023
Introduces laboratory electronics for physical science students. Includes basic electronic instruments, dc bridge circuits, operational amplifiers, bipolar transistors, field-effect transistors, photodiodes, noise in electronic circuits, digital logic and microcontrollers. Students gain hands-on experience in designing, building and debugging circuits. Two lectures and one three hour laboratory per week. Concludes with a three-week project in which students design and build an experiment of their choice and present a seminar on the results.
PHYS 4230 - Thermodynamics and Statistical Mechanics
Statistical mechanics applied to macroscopic physical systems; statistical thermodynamics, classical thermodynamics systems; applications to simple systems. Examines relationship of statistical to thermodynamic points of view.
PHYS 4430 - Advanced Laboratory
Fall 2019 / Spring 2022 / Fall 2022
Two lectures, one lab per week. Experiments introduce students to realities of the experimental physics so they gain a better understanding of theory and an appreciation of the vast amount of experimental work done in the physical sciences today. Same as PHYS 5430.
