B: Quantum Semiclass

Abstract. Second-harmonic generation in the no-energy-transfer regime can be a source of quasi-stationary sub-Poissonian light as was recently shown by Bajer et al (Bajer J, Haderka O and Peřina J 1999 J. Opt. B: Quantum Semiclass. Opt. 1 529). We generalize their results for higher-harmonic generation by applying the numerical method of Hamiltonian diagonalization and the analytical semiclassical description of classical trajectories. The quasi-stationary behaviour of the sub-Poissonian photocount noise in the no-energy-transfer regime is explained. An approximate formula for the Fano factor is derived for arbitrary harmonics. It is predicted that the deepest quasi-stationary reduction of photocount noise in the no-energy-transfer regime is achieved in the third-harmonic generation

Qubit-induced phonon blockade as a signature of quantum behavior in nanomechanical resonators

The observation of quantized nanomechanical oscillations by detecting femtometer-scale displacements is a significant challenge for experimentalists. We propose that phonon blockade can serve as a signature of quantum behavior in nanomechanical resonators. In analogy to photon blockade and Coulomb blockade for electrons, the main idea for phonon blockade is that the second phonon cannot be excited when there is one phonon in the nonlinear oscillator. To realize phonon blockade, a superconducting quantum two-level system is coupled to the nanomechanical resonator and is used to induce the phonon self-interaction. Using Monte Carlo simulations, the dynamics of the induced nonlinear oscillator is studied via the Cahill-Glauber $s$-parametrized quasiprobability distributions. We show how the oscillation of the resonator can occur in the quantum regime and demonstrate how the phonon blockade can be observed with currently accessible experimental parameters

Long-term neutralization of acidic condensate from gas condensing boilers

The pH of wastewater needs to remain between 6 and 9 to protect water organisms. Condensates from a gas condensing boiler have a pH value of about 3. An optimal way to neutralize the acid condensate is to use cheap material such as dolomite. An old-style neutralization box (NB) was tested with a standard faction of dolomite. However, it did not sufficiently neutralize the condensate. Therefore, several tests were performed involving changes to the construction of the neutralization box, a finer fraction of dolomite and aerating the condensate in the neutralization box. In summary, a new NB technology with partitions, a finer fraction of dolomite and condensate aeration proved sufficient in the neutralization of the pH of the condensate in the short and long terms. It depends on what material the heat exchanger is made of in the condensing boiler. The aluminum content reduces the effectiveness of dolomite in the long run, so aerating the condensate in the NB is recommended, which leads to its more effective neutralization.Web of Science1422art. no. 1501

Sub-Poissonian behaviour in the second harmonic generation

Abstract. A special class of quantum solutions of the second harmonic generation process exhibiting time-stable sub-Poissonian behaviour with Fano factor F ≈ 0.83 is numerically analysed. A theoretical prediction of that specific Fano number and an explanation of the extraordinary time stability of the sub-Poissonian behaviour is given using the semiclassical method of classical trajectories. Keywords: Photon statistics, sub-Poissonian statistics, Fano factor, second harmonic generation (SHG) Much experimental and theoretical attention has been devoted to the second harmonic generation (SHG) process since the first successful SHG by Franken in 1961 [1]. This process represents a special case of the processes described by the interaction Hamiltonian where a 1 and a 2 denote annihilation operators of the fundamental and second harmonic modes and g is a nonlinear coupling parameter. Unfortunately, no exact solution of quantum dynamics described by (1) can be found and many analytical approximations or numerical methods have to be used for describing the conversion efficiency, quantum noise statistics and other characteristics of the process An important noise parameter of photon statistics is the variance of photon number Var(n). If it is smaller than the mean photon number, i.e. Var(n) < n we call such light sub-Poissonian and it represents an example of non-classical light. In experiments, the Fano factor F = Var(n) n is often used for the description of the photon statistics. Apparently, the light is sub-Poissonian when F < 1. Such light has been generated and observed in many laboratories For coherent inputs α 1 = r 1 exp(iφ 1 ) and α 2 = r 2 exp(iφ 2 ), the short-time approximation (gt 1) gives the well known results (see, e.g., [6]) where the initial phase difference θ = 2φ 1 − φ 2 decides whether the process ω + ω → 2ω or the reversed process is realized and whether sub-Poissonian or super-Poissonian light is generated in the first moment of the interaction. In a spontaneous SHG process (α 2 = 0) sub-Poissonian light is generated as well and it holds that [6] whereas in a process (α 1 = 0) no sub-Poissonian light is generated (F 1,2 > 1) and only quadrature-squeezed light can be observed. For long interaction (i.e. the condition gt 1 is not fulfilled) no analytical predictions exist and numerical methods must be applied. We have used a well known method of diagonalization of the Hamiltonian used originally i
