Microscopic origins of inertial magnetization dynamics
Caleb Webb, Ling Gan, Shufeng Zhang
Ultrafast experiments have uncovered inertial magnetization dynamics in ferromagnets, but their microscopic origin remains elusive. Using a non-Markovian quantum master equation we…
Colossal Magnon Magnetoresistance of Two-Dimensional Magnets
Caleb M Webb, Shufeng Zhang
The magnon current holds substantial importance in facilitating the transfer of angular momentum in spin-based electronics. However, the magnon current in three-dimensional magneti…
How to Partition a Quantum Observable
Caleb M. Webb, Charles A. Stafford
We present a partition of quantum observables in an open quantum system which is inherited from the division of the underlying Hilbert space or configuration space. It is shown tha…
Work Sum Rule for Open Quantum Systems
Parth Kumar, Caleb M. Webb, Charles A. Stafford
A key question in the thermodynamics of open quantum systems is how to partition thermodynamic quantities such as entropy, work, and internal energy between the system and its envi…
