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…
Matrix product states and numerical mode decomposition for the analysis of gauge-invariant cavity quantum electrodynamics
Christopher J. Ryu, Dong-Yeop Na, Weng C. Chew
There has been a problem of gauge ambiguities with the Rabi Hamiltonian due to the fact that it can be derived from two formally different but physically equivalent fundamental Ham…
