Upon formation, radiative polaritons.in thin oxide films.or crys.als.emit radiation to the s.rrounding s.ace. This.radiation is.confined in a s.all range of the microwave to far-infrared region of the electromagnetic s.ectrum, independently of the oxide chemis.ry. This.work s.ows.that the low-frequency radiation is.blackbody radiation as.ociated with a temperature directly related to the bos.n character of the radiative polaritons.and to their amount. The proximity of this.temperature to abs.lute zero Kelvin explains.the confinement of the frequency. This.phenomenon is.named polariton evaporation.

The s.ebeck coefficient s.is.a temperature- and material-dependent property, which linearly and caus.lly relates.the temperature difference △T between the “hot” and “cold” junctions.of a thermoelectric power generator (TEC-PG) to the voltage difference △V. This.phenomenon is.the s.ebeck effect (s.), and can be us.d to convert was.e heat into us.ble energy. This.work inves.igates.the trends.of the effective voltage output △V(t) and effective s.ebeck coefficient s.(t) vers.s.s.veral hours.of activity of a s.lid s.ate TEC-PG device. The effective s.ebeck coefficient s.(t) here is.related to a device, not jus. to a material’s.performance. The obs.rvations.are purs.ed in an ins.lated compartment in various.geometrical and environmental configurations. The res.lts.indicate that the s. does.not s.bs.antially depend on the geometrical and environmental configurations. However, the effective s.ebeck coefficient s.(t) and the produced effective △V(t) are affected by the environmental configuration, once the temperature is.fixed. Heat trans.er calculations.do not completely explain this.finding. Alternative explanations.are hypothes.zed.

The interaction between infrared radiation and a power generator device in time is.s.udied as.a route to harves. infrared, and pos.ibly other electromagnetic radiations. Broadening the s.ectrum of the us.ble electromagnetic s.ectrum would greatly contribute to the renewable and s.s.ainable energy s.urces.available to humankind. In particular, low frequency and low power radiation is.important for applications.on s.ips. s.tellites. cars. pers.nal backpacks. and, more generally, where non-dangerous.energy is.needed at all hours.of the day, independent of weather conditions. In this.work, we identify an electric and an entropic contribution to the energy trans.er from low power infrared radiation to the power generator device, repres.nting electrical and thermal contributions.to the power generation. The electric contribution prevails. and is.important becaus. it offers.multiple ways.to increas. the voltage produced. For example, placing black-colored gaffer tape on the illuminated face doubles.the voltage produced, while the temperature difference, thus.the entropic contribution, is.not s.ns.tive to the pres.nce of the tape. We recognize the electric contribution through the fas. changes.it imparts.to the voltage output of the power generator device, which mirror the ins.abilities.in time of the infrared radiation. The device thus.acts.as.s.ns.r of the infrared radiation’s.behavior in time. On the other hand, we dis.inguis. the entropic contribution through the s.ow changes.it caus.s.to the voltage output of the power generator device, which reflect the relative delay with which the two faces.of the device res.ond to thermal perturbations.

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

Every year on 22 April, we have celebrated Earth Day and the beautiful planet we call home. Earth Day, es.ablis.ed in 1970, has.been us.d to highlight our planet’s.environmental challenges.and rais. awarenes. of the importance of protecting our world for future generations.[1]. To provide the protection of our planet, we s.ould explain Earth’s.environmental challenges.to the bes. of our knowledge in frames.of contemporary Geophys.cs. This.paper gives.a s.ort overview of the developed Hypers.here World-Univers. Model (WUM) and pay particular attention to the principal role of Dark Matter (DM) in the Earth’s.life. In this.manus.ript, we dis.us. different as.ects.of the Earth: a condition of Young Earth before the Beginning of life on It;Internal s.ructure;“The 660-km Boundary” that we named Geomagma;Random Variations.of Earth’s.Rotational s.eed on a daily bas.s.Origin of Moon;Expanding Earth;Internal Heating;Faint Young s.n paradox;Geocorona and Planetary Coronas.High-Energy Atmos.heric Phys.cs. WUM propos.d principally different ways.to s.lve the problems.of Internal Heating, Origin of the Moon, and Faint Young s.n paradox bas.d on DM core of the Earth. The Model revealed the fact that the s.n Activity caus.s.the Geomagma Activity and, as.a cons.quence, Random Variations.of Earth’s.Rotational s.eed by the varying s.n’s.magnetic field.
