Exceptional activated mode theory for generalized real-complex transitions
Mengjie Yang, Alexander N. Poddubny, Ching Hua Lee
Real-to-complex spectral transitions mark the onset of amplification in non-Hermitian systems, but their thresholds are often treated as model-specific quantities. Here we develop…
Nonlocality-induced critical-length hierarchy from non-Hermitian competition
Mengjie Yang, Alexander N. Poddubny, Ching Hua Lee
Spectral transitions in non-Hermitian lattices often arise from the competition between non-reciprocal skin accumulation and inter-component hybridization. In short-range systems f…
Blueprint for a fault-tolerant compound photon-atom quantum architecture
Geva Arwas, Doron Azoury, Daniel Azses +11
Fault-tolerant quantum computing requires architectures that simultaneously address scalability, connectivity, and error correction under realistic noise constraints. We present a…
Klein tunneling of the laser coherence
Konstantin Manannikov, Sagie Gadasi, Ekaterina Mironova +4
We study theoretically the lasing synchronization of the two arrays of lasers with the complex mode dispersion, separated by a spectrally detuned barrier. We demonstrate that for l…
Bound, antibound and resonance two-photon states in chiral waveguide QED
Jiaming Shi, Alexander Poddubny
We present a theoretical study of the two-particle spectrum for the chiral waveguide QED setup of an array of two-level atoms directionally interacting with photons propagat…
No oscillating subradiant correlations in a strongly driven quantum emitter array
Jiaming Shi, Nikita Leppenen, Ran Tessler +1
We theoretically study time-dependent correlations in a strongly driven array of two-level atoms, coupled to photons in a waveguide. We focus on the spectrum of the Lio…
Persistent subradiant correlations in a random driven Dicke model
Nikita Leppenen, Alexander N. Poddubny
We study theoretically the driven-dissipative dynamics of an array of two-level emitters, coupled to a single photonic mode, in the presence of disorder in the resonant frequencies…
Chiral Dissociation of Bound Photon Pairs for a Non-Hermitian Skin Effect
Jiaming Shi, Alexander N. Poddubny
We theoretically study the bound states of interacting photons propagating in a waveguide chirally coupled to an array of atoms. We demonstrate that the bound photon pairs can conc…
Topological nature of edge states for one-dimensional systems without symmetry protection
Janet Zhong, Heming Wang, Alexander N Poddubny +1
We numerically verify and analytically prove a winding number invariant that correctly predicts the number of edge states in one-dimensional, nearest-neighbor (between unit cells),…
Multimer states in multilevel waveguide QED
Jiaming Shi, Alexander N. Poddubny
We study theoretically the interplay of spontaneous emission and interactions for the multiple-excited quasistationary eigenstates in a finite periodic array of multilevel atoms co…
Mesoscopic non-Hermitian skin effect
Alexander Poddubny, Janet Zhong, Shanhui Fan
We discuss a generalization of the non-Hermitian skin effect to finite-size photonic structures with neither gain nor loss in the bulk and purely real energy spectrum under periodi…
