Efficient tensor-network simulation for the few-atom multimode Dicke model via coupling-matrix transformation
Christopher J. Ryu, Dong-Yeop Na, Weng C. Chew +1
We present a novel generalization of the chain mapping technique that applies to multi-atom, multimode systems by making use of coupling matrix transformations. This is extremely u…
Numerical Framework for Modeling Quantum Electromagnetic Systems Involving Finite-Sized Lossy Dielectric Objects in Free Space
Dong-Yeop Na, Thomas E Roth, Jie Zhu +2
The modified Langevin noise formalism has been proposed for the correct charaterization of quantum electromagnetic fields in the presence of finite-sized lossy dielectric objects i…
Generalized Helmholtz Decomposition for Modal Analysis of Electromagnetic Problems in Inhomogeneous Media
Jie Zhu, Thomas E. Roth, Dong-Yeop Na +1
Potential-based formulation with generalized Lorenz gauge can be used in the quantization of electromagnetic fields in inhomogeneous media. However, one often faces the redundancy…
