Nonlinear dynamical Casimir effect and Unruh entanglement in waveguide QED with parametrically modulated coupling

Egor S. Vyatkin, Alexander V. Poshakinskiy, Alexander N. Poddubny

We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide. This motion can be implemented mechanically or simulated via the modulation of t…

Bound state of distant photons in waveguide quantum electrodynamics

Alexander V. Poshakinskiy, Alexander N. Poddubny

Quantum correlations between distant particles remain enigmatic since the birth of quantum mechanics. Here we predict a novel kind of bound quantum state in the simplest one-dimens…

Long persistent anticorrelations in few-qubit arrays

Danil Kornovan, Alexander Poddubny, Alexander Poshakinskiy

We consider theoretically the mechanisms to realize antibunching between the photons scattered on the array of two-level atoms in a general electromagnetic environment. Our goal is…

Two-photon pulse scattering spectroscopy for arrays of two-level atoms, coupled to the waveguide

Ekaterina Vlasiuk, Alexander V. Poshakinskiy, Alexander N. Poddubny

We have theoretically studied the scattering of two-photon pulses from a spatially-separated array of two-level atoms coupled to the waveguide. A general analytical expression for…

Quantum vortices of strongly interacting photons

Lee Drori, Bankim Chandra Das, Tomer Danino Zohar +4

Vortices are a hallmark of topologically nontrivial dynamics in nonlinear physics and arise in a huge variety of systems, from space and atmosphere to condensed matter and quantum…

Resonant Parametric Photon Generation in Waveguide-coupled Quantum Emitter Arrays

Egor S. Vyatkin, Alexander V. Poshakinskiy, Alexander N. Poddubny

We have developed a theory of parametric photon generation in the waveguides coupled to arrays of quantum emitters with temporally modulated resonance frequencies. Such generation…
