“…Figure 3(a) shows ∆ω 1,2 as a function of N along with the linewidth δω 2 = Im[2λ (2) i ] of the most harmonic eigenstate in the two-excitation subspace -increasing the number of emitters makes the system's energy levels more equally spaced while saturating their linewidths, thereby worsening photon blockade. It is worth noting that with the weakly coupled emitters the value of the min[g (2) (0; ω L )] has an initial decrease, before monotonically increasing with the number of emitters consistent with previously reported results [10]. We also observe a pronounced 'bunching' peak in g (2) (0; ω L ) for strongly coupled emitters [ Fig.…”

“…Atomic and solid state CQED systems with a few two-level emitters have exhibited a rich set of quantum phenomena in transmission statistics, including, but not limited to, the vacuum Rabi oscillations [1,2], the conventional and the unconventional photon blockade [3][4][5], and the photon-induced tunneling [6]. While suitable approximations can provide understanding of the eigenstructure of multi-element CQED systems [9,10] obtained in experiments [11,12], the numerical studies of light-emission and scattering from this system have been limited due to the exponential scaling of the Hilbert space with the number of emitters.…”

We use the scattering matrix formalism to analyze photon blockade in coherently-driven CQED systems with a weak drive. By approximating the weak coherent drive by an input single-and two-photon Fock state, we reduce the computational complexity of the transmission and the two-photon correlation function from exponential to polynomial in the number of emitters. This enables us to easily analyze cavity-based systems containing ∼50 quantum emitters with modest computational resources. Using this approach we study the coherence statistics of photon blockade while increasing the number of emitters for resonant and detuned multi-emitter CQED systems -we find that increasing the number of emitters worsens photon blockade in resonant systems, and improves it in detuned systems. We also analyze the impact of inhomogeneous broadening in the emitter frequencies on the photon blockade through this system.

“…For mesoscopic SEs in a cavity, solutions for the quan-tum dynamics have so far been achieved only for few limited cases such as for very weak excitations, where only a couple of low-excitation states are considered [41]. Alternatively, L[ρ] can be approximated by an effective Hamiltonian [42,43] in the weak excitation regime where quantum jumps are neglected. In turn, quantum trajectories include jumps but are limited to few spins [44,45].…”

Mesoscopic spin ensembles coupled to a cavity offer the exciting prospect of observing complex nonclassical phenomena that pool the microscopic features from a few spins with those of macroscopic spin ensembles. Here, we demonstrate how the collective interactions in an ensemble of as many as hundred spins can be harnessed to obtain a periodic pulse train of nonclassical light. To unravel the full quantum dynamics and photon statistics, we develop a time-adaptive variational renormalization group method that accurately captures the underlying Lindbladian dynamics of the mesoscopic spin-cavity system.

Pulsed coherent drive in the Jaynes-Cummings model

The Jaynes-Cummings system is one of the most fundamental models of how light and matter interact. When driving the system with a coherent state (e.g. laser light), it is often assumed that whether the light couples through the cavity or atom plays an important role in determining the dynamics of the system and its emitted field. Here, we prove that the dynamics are identical in either case except for the offset of a trivial coherent state. In particular, our formalism allows for both steady-state and the treatment of any arbitrary multimode coherent state driving the system. Finally, the offset coherent state can be interferometrically canceled by appropriately homodyning the emitted light, which is especially important for nanocavity quantum electrodynamics where driving the atom is much more difficult than driving the cavity.In this work, we study the Jaynes-Cummings (JC) Hamiltonian driven by a coherent state. The JC system consists of a single bosonic mode (e.g. an electromagnetic cavity) coherently interacting with a single fermionic mode (e.g. an electron or two-level atom). These modes are radiatively coupled to external reservoirs, which can cause the system to both leak or absorb energy depending on their state. Preparing the reservoirs with coherent light is one of the most common ways of pumping energy into the system, and provides an excellent way to understand its quantum-mechanical responses. Despite the simplicity of the JC model itself (Fig. 1), it gives rise to a variety of complex phenomena when driven. For example, vacuum Rabi splitting [1, 2], photon blockade [3-5] and tunneling [6], bistability [7, 8] or symmetry breaking [9], squeezed states [10], Mollow triplets [11] or state dressing [12], and a rich structure of multi-photon resonances [13,14] have all been observed, as well as finding use in the readout of qubits [15,16]. There are multiple ways to drive the JC system, as shown in Fig. 1. In particular, the coherent state could be prepared in the reservoirs coupled to the cavity or coupled to the atom [17]. Almost all of the above studies have shown substantive differences in observed radiation from FIG. 1.

The cavity couples to the reservoir b, while the two-level atom couples to reservoir c. † These authors contributed equally.
