Nonreciprocal Coupling Induced Non-Hermitian Entanglement in Optomechanical Systems
W. Y. Hu, H. Yi, H. N. Liu +4
Quantum entanglement, one of the most intrinsic properties of quantum mechanics, corresponds to a key resource for quantum information. Exceptional points (EPs) are special phase t…
Quantum Integration Networks for Efficient Monte Carlo in High-Energy Physics
Heechan Yi, Kayoung Ban, Myeonghun Park +1
Monte Carlo methods play a central role in particle physics, where they are indispensable for simulating scattering processes, modeling detector responses, and performing multi-dim…
Nonreciprocity and unidirectional invisibility in three optical modes with non-Markovian effects
H. Yi, T. Z. Luan, W. Y. Hu +4
In this work, we construct three coupled optical modes systems to obtain effective Hamiltonian mediated by coherent dissipative coupling during adiabatic elimination of large dissi…
Nonreciprocal quantum router with non-Markovian environments
T. Z. Luan, Cheng Shang, H. Yi +4
Quantum routers are essential elements of quantum networks, enabling coherent information transfer between distant nodes. While their behavior has been extensively studied under Ma…
Energy gap and London penetration depth of MgB_2 films determined by microwave resonator measurement
N. Klein, B. B. Jin, J. Schubert +5
We have measured the temperature dependence of the microwave surface impedance Z_s = R_s + iΩμ_0 of a MgB2 film at a frequency Ω/2Πof 18 GHz employing a dielectric resonator techni…
