当如恩受阿那亚开发团队之委托,为秦皇岛的滨海度假区设计一座艺术中心时,面临着这样一个难题:如何从直白的场地环境中梳理出概念方案?阿那亚艺术中心位于渤海海岸旁一个新型社区内,具有与地中海气候相似的人造都市肌理。这种“迪士尼化”的建设在中国并不罕见,但问题是该如何创造出既能满足项目要求并融入当地环境,又能为社区发展带来新鲜血液的建筑。幸运的是,具有远见的业主希望设计拥有永恒经典的特质,并期望这个项目能够成为真实代表秦皇岛的地区符号,突显秦皇岛地区季节性变化与贴近自然的特色。

A Thermal Analogue of the Zel’Dovich Effect

引用

Journal of Applied Mathematics and Physics 2023年第12期11卷 3970-3983页

作者： gianpaolo Bei Department of Basic and Applied Sciences for Engineering Sapienza University Rome Italy

We analyze in this work anisotropic heat conduction induced by a harmonically oscillating laser source incident on rotating conductors, exploiting an analogy with an effect discovered long ago, called the Zel’dovich effect. We re-covered the main results of a recently published paper that predicts the translational Doppler frequency shift of a thermal wave induced on a sample moving with uniform rectilinear motion. We extend then this framework to take into account the frequency shift of a thermal field propagating on a rotating platform. We show that it coincides with the rotational frequency shift which has been recently observed on surface acoustic waves and hydrodynamic surface waves, called rotational superradiance. Finally, we use an analogy with the Tolman effect to deduce a simple estimate of the average temperature gradient induced by rotation, showing the existence of a new cooling effect associated with heat torque transfer.

Vacuum Correlations, Detector Efficiency Fluctuations and Classical Dynamic Violations of CH-Inequality

引用

Journal of Applied Mathematics and Physics 2023年第6期11卷 1677-1692页

作者： gianpaolo Bei Department of Basic and Applied Sciences for Engineering Sapienza University of Rome Rome Italy

We study in this paper the possible influence of vacuum fluctuations on photo detection and its background noise in Bell tests. We analyze its consequences on the standard statistical analysis of data showing that it is not fulfilled anymore the conventional hypothesis of a Poisson like probability density distribution of single photodetection events. We assume that vacuum fluctuations are due to real and measurable fluctuating fields, as recently confirmed experimentally, and that their non null correlations outside the light cone contribute to photon coincidence rates making them time dependent. We introduce a generalized Bell like correlation function which contains a new term due to supposed vacuum induced photon counting events. We deduce then a generalization of CH-inequality which takes in account the effect of these vacuum electric fields on detector efficiency. We predict an apparatus temperature fluctuations during photon detection which we suggest could be observed by looking for colored noise thermal emission of the photodetectors, generalizing the standard white noise prediction of C.S.L. models on wave function collapse postulate. We discuss an experimental test of this prediction, based on the idea of inducing a thermal wave on the whole quantum detectors, aimed to observe time dependent deviations from standard stationary statistical predictions of Quantum Mechanics.

Vacuum Dependent Bell Local Hidden Variable Models and Generalized C.H.S.H. Inequalities

引用

Journal of Applied Mathematics and Physics 2022年第1期10卷 11-20页

作者： gianpaolo Bei Department of Basic and Applied Sciences for Engineering Sapienza University of Rome Rome Italy

We extend a previous model of the author which generalizes Bell local hidden variable models to the case of entangled photon pairs assuming that the standard Bell correlation functions depend on a hidden vacuum index. We deduce a generalization of Bell theorem assuming that classical observables are not dichotomic and that photon pair emission and detection is not a stationary stochastic process. We derive a photon imperfect polarization correlation functions due to rotational invariance breaking induced by hidden vacuum spin currents. We implement formally this approach deducing a generalization of C.H.S.H. inequalities which asymptotically converges to the standard one and which might be competitive with standard quantum mechanics predictions. We suggest to test this inequalities conceiving new E.P.R.-Bell like tests with time dependent detector efficiency and photon flux. Finally, we suggest to apply these generalized inequalities to the correlation functions of entangled classical spinning waves realized recently with metamaterials.
