Abstract

The mechanism of avian navigation is an important question for global scientists. One of the most famous candidates is the radical pair mechanism (RPM), which shows that avian navigation is achieved by detecting the amount of products from chemical reactions, which exhibit different properties for singlet and triplet spin states. Based on the theory, we explore the amount of the the singlet recombination product by changing the coupling strength and direction of the magnetic field. The radical pair in our model is coupled with a Lipkin-Meshkov-Glick (LMG) bath, which proposes attractive results at quantum phase transition (QPT) point, especially when the magnetic field is parallel with the original direction of the pair. We find weakest navigation ability in QPT point according to one of our proposing methods. And we find invariant subspace in our Hamiltonian when the magnetic field is vertical to the plane of the radical pair and the bath, which will greatly speed up our calculation. Our results could help the exploration of the design principle of artificial avian navigation., 8 pages, 6 figures

Abstract

A controllable non‐reciprocal transmission model is proposed. The model contains a Möbius ring, which is connected with two 1D semi‐infinite chains, with a two‐level atom located inside one of the cavities of the Möbius ring. The Green function method is used to study the transmittance of a single photon through the model. The results show that non‐reciprocal transmission can be achieved in this model and the two‐level atom can behave as a quantum switch for non‐reciprocal transport of the single photon. This controllable non‐reciprocal transmission model may inspire new quantum non‐reciprocal devices. [ABSTRACT FROM AUTHOR]
