Jonas Karthein

Jonas Karthein is an Assistant Professor at the Department of Physics and the Cyclotron Institute of Texas A&M University. His research focuses on experimental nuclear physics, leveraging atomic/molecular/optical (AMO) techniques to study stable and radioactive atoms and molecules for exploring fundamental symmetries in physics.

• Research Areas: Nuclear structure, electroweak effects, parity violation, nuclear anapole moments, dark matter/energy, nuclear electric dipole moments (EDM), precision laser spectroscopy, ion trapping, and quantum sensing.
• Affiliations: Texas A&M University (current), MIT (collaboration), FRIB (U.S. Facility for Rare Isotope Beams), CERN/ISOLDE (European facility).

Experimental Focus: Karthein’s lab develops ultra-sensitive laser spectroscopy methods in ion traps to investigate symmetry-violating nuclear effects using radioactive molecules. His work has implications for nuclear physics, quantum chemistry, astrophysics, and medical isotope applications.

Publications: His recent studies include electromagnetic properties of indium isotopes, electroweak effects in Penning trap molecular ions, nuclear charge radii of silicon isotopes, and fundamental physics research with radioactive molecules. These studies emphasize parity violation, dark matter, and nuclear EDMs.

Scientific Recognition: His 2025 publication in Phys. Rev. C was designated an Editor's Suggestion, highlighting its significance.

Lab Development: The Karthein Lab at Texas A&M is establishing a dedicated facility for quantum sensing of radioactive molecules, with collaborations at MIT, FRIB, and CERN/ISOLDE.
