• January: Ji is invited to give a talk on "Entangling spin qubits via magnon-mediated dissipative couplings" at Huazhong University of Science and Technology (Wuhan, China)!

2022

• Ji received the Georg H. Endress Postdoc Fellowship! 

• Ji moved to University of Basel and now is working with Professor Daniel Loss!

• Ji attended the SPIN QUBIT 5 conference at Pontresina, a wonderful place! Ji also gave a poster presentation on "Bell state generation via dissipative couplings"!

• Our paper "Domain wall qubit on magnetic racetrack" is on ArXiv now!

2021

• Ji received the Outstanding Teaching Fellow of the Year Award, because of his excellent teaching in Graduate Quantum Mechanics, Graduate Statistical Physics, and Mathematical Methods for Physicists in 2021!

• Ji received the Dissertation Year Fellowship! 

• Our paper "Bell-state generation for spin qubits via dissipative coupling" is out! In this work, we show that a magnet can act as a coupler for distant spin qubits for entanglement generation (and even Bell state when complemented by proper postselection).

• Our paper "Direct observation of 3D topological spin textures and their interactions using soft x-ray vector ptychography" is out! It is a nice collaboration with John's experimental group at UCLA! In this work, we directly observe topological magnetic monopoles and their interactions (with a spatial resolution of 10 nm, comparable with exchange length) in a ferromagnetic meta-lattice.

• Our paper "Controlled topological charge injection in topological matters" is out! This is a conceptual paper, where we offer a new systemic view to think about the relation between edge mode and topological excitations in a topologically nontrivial bulk.

• Our paper "Zeeman term for the Néel vector in a two sublattice antiferromagnet" has been published in Physical Review B! It is a nice collaboration with Sayak!  In this work, we discuss the dynamics of various topological spin textures in two sublattice antiferromagnetic in the presence of Dzyaloshinsky-Moriya interactions.

2020

• Our paper "Quantum hydrodynamics of spin winding" has been published in Physical Review B! This work formulates a quantum hydrodynamics of an easy-plane spin winding in a quantum spin chain.

• Our paper "Energy storage in magnetic textures driven by vorticity flow" has been published in Physical Review B as Rapid Communication! This work proposes an experimentally feasible energy-storage concept associated with the magnetic winding texture, based on vorticity (hydro)dynamics within an easy-plane magnet.

• Ji was selected as the CQSE Graduate Fellow and received the 2020 CQSE Graduate Fellowship. 

The Center for Quantum Science and Engineering (CQSE) was recently established by the School of Engineering and Applied Science and the Division of Physics Sciences at UCLA to coordinate research in the field of quantum information science.

• Our paper "Topological transport of vorticity in Heisenberg magnets" has been published in  Physical Review B as Rapid Communication! This work studies a robust topological transport carried by magnetic vortices, based on the topological conservation of vorticity.
