Learning Together: A Format for Reflective Turn-Based Sharing in STEM Communities
James Day, Katherine R. Herperger, Kyle Monkman
Here, we present \textit{Learning Together}: a simple, low-cost format for structured speaking and listening on historical, cultural, and equity-related topics within a physics com…
Spectral switching of autonomous quantum operations
Man Yin Cheung, Mona Berciu, Kyle Monkman
We introduce a framework for implementing quantum operations as steady states of a subsystem in an extended Hilbert space. Each operation has a spectral criterion for reaching the…
Limits of the non-Hermitian description of decay models
Kyle Monkman, Mona Berciu
We present a general proof that non-Hermitian dynamics and Lindblad dynamics with only decay terms are equivalent in the highest particle subspace. We then propose an unbiased meth…
Persistent spin currents in superconducting altermagnets
Kyle Monkman, Joan Weng, Niclas Heinsdorf +2
Superconductors are famously capable of supporting persistent electrical currents, that is, currents that flow without any measurable decay as long as the material is kept in the s…
Hidden zero modes and topology of multiband non-Hermitian systems
K. Monkman, J. Sirker
In a finite one-dimensional non-Hermitian system, the number of zero modes does not necessarily reflect the topology of the system. This is known as the breakdown of the bulk-bound…
