# Opportunities

## Seeking a Postdoctoral Researcher (W20086) *theoretical physics

Deadline: Open until filled

iTHEMS is seeking a postdoctoral researcher in theoretical physics including condensed matter physics, particle physics and nuclear physics. In particular, the successful applicant is expected to help develop an adiabatic quantum computer (AQC) simulator using time-dependent density matrix renormalization group (DMRG). This project is part of a greater effort in the Berkeley area towards exploring the efficacy of adiabatic quantum computing supported jointly by RIKEN, UC Berkeley, Lawrence Berkeley Lab, and the U.S. Department of Energy. In addition to developing the AQC simulator, the candidate will have the opportunity to pursue top-level research in collaboration with an interdisciplinary group of researchers across fields such as mathematics, physics, chemistry, life sciences, engineering computational sciences, information sciences, and social sciences at iTHEMS, and physics, mathematics and computational sciences at Berkeley.

## Seeking a Research Scientist or Senior Research Scientist (W20095) *extreme universe

Deadline: Open until filled

iTHEMS is seeking theorist(s) working on extreme universe including high-energy astrophysics, supernovae, neutron stars, black holes, and early universe. Successful applicant(s) are expected not only to pursue top-level researches in astrophysics but also to lead interdisciplinary collaborations among different fields such as mathematics, physics, chemistry, life sciences, engineering, computational sciences, information sciences, and social sciences, under the concept of iTHEMS. Also, successful applicant(s) are expected to participate in the international collaboration on astrophysics between iTHEMS and the NSF Physics Frontier Center in UC Berkeley established on Sept. 2020.

## Seeking a Postdoctoral Researcher (W20122) *ecology and evolutionary biology

Deadline: Open until filled

iTHEMS is seeking postdoctoral researcher(s) in the field of ecology and evolutionary biology (including population genetics, epidemiology, quantitative biology, and bioinformatics). Successful applicant(s) are expected to not only pursue high quality research in their own field but also promote interdisciplinary collaborations among different fields such as mathematics, physics, chemistry, life sciences, engineering, computational sciences, information sciences, and social sciences, under the concept of iTHEMS. This time, we encourage early-career applicants who have a high research potential in pursuing collaboration with Dr. Ryosuke Iritani (ecology and evolution) as well as various iTHEMS-researchers across disciplines. Though your research backgrounds in population-/community-dynamics, stochastic analysis, evolutionary game theory, and stochastic simulations are highly beneficial, we value your research proposal (concreteness, logicality, and realizability of your future plans) more than your past achievements.
