We consider the reflection and transfer properties on controlling the impact of several parameters, such as inter-particle distance, coupling strength, detuning and so on. The characteristics of our investigation is that when the frequency of the incoming single photon are nearly similar to one of eigenfrequencies of an additional QD, our proposed the system acts as a directional quantum splitter with a high transfer ratio toward the specific path. That is, the incident single photons could be come out of only one side of infinite waveguide with the transfer rate of over 0.5 because the additional QD absorbs the energy of single photons through the coherent interaction. These properties could be unlocked new opportunities to realize the quantum communication networks and quantum computation systems based on practical single-photon switch or quantum logic gates.</p></div>","PeriodicalId":641,"journal":{"name":"Journal of Low Temperature Physics","volume":"218 3-4","pages":"224 - 238"},"PeriodicalIF":1.1,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A combination of linear programming, genetic algorithms, and nonlinear programming was employed to design an actively shielded 3 T superconducting MRI magnet system. This magnet consists of seven main coils and two shielding coils, achieving a magnetic field with a peak-to-peak inhomogeneity of 10 ppm within a 50-cm-diameter spherical volume (DSV). To address the risk of quench in superconducting magnets, which can lead to damage due to excessive temperature, voltage, and stress, a quench protection system is crucial. The designed system segments the coils for protection, using diode pairs and shunt resistors to manage the quench. Initial simulations indicated that temperature rises and voltages were within safe limits, but some coils were slow to quench or did not quench at all, risking burnout. To mitigate this, quench propagation heating plates were added to increase the quench speed. Updated simulations showed rapid quench across all coils and a significant reduction in hot spot temperatures and peak voltages.</p></div>","PeriodicalId":641,"journal":{"name":"Journal of Low Temperature Physics","volume":"218 3-4","pages":"146 - 165"},"PeriodicalIF":1.1,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
