Chirally-symmetric-like unconventional magnon blockade in a dissipative cavity-magnon system
We present a theoretically versatile and controllable framework for realizing chirally-symmetric-like unconventional magnon blockade within a cavity-magnon system composed of a yttrium iron garnet sphere and a cross-line microwave circuit, where the cavity mode is driven by a two-photon driving field. Under optimal conditions regarding the driving strength and phase of this two-photon field, we observe that magnon blockade exhibits chiral-like symmetry even in high-dissipation scenarios. However, the introduction of coherent coupling leads to energy level splitting that counteracts the energy level attraction induced by dissipative coupling, thereby diminishing the blockade effect. Furthermore, we clarify that the energy level attraction resulting from dissipative coupling remains invariant with respect to variations in the phase of this coupling coefficient. Our approach offers promising applications for tunable single-magnon sources and quantum information processing.

期刊介绍:
Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics.
Results in Physics welcomes three types of papers:
1. Full research papers
2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as:
- Data and/or a plot plus a description
- Description of a new method or instrumentation
- Negative results
- Concept or design study
3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
