• Abstract: Proposed recently by the author Q-ball mechanism of the pseudogap state and high-Tc superconductivity in cuprates (2022) was supported by micro X-ray diffraction data in HgBa$_2$CuO$_{4+y}$ (2023). In the present paper it is demonstrated that T-linear temperature dependence of electrical resistivity arises naturally in the Q-ball gas phase, that may explain corresponding experimental data in the "strange metal" phase of high-T$_c$ cuprates, as reviewed by Barisic et al. (2013). In the present theory it arises due to scattering of electrons on the Q-balls gas of condensed charge/spin fluctuations. Close to the lowest temperature boundary of the "strange metal" phase, at which Q-ball radius diverges, electrical resistivity caused by a slide of the Q-balls as a whole is calculated using fluctuation paraconductivity calculation method by Alex Abrikosov (1987). The diamagnetic response of Q-balls gas is calculated as well and shows good accord with experimental data by L.Li et al. (2010) in the "strange metal" phase. In total, obtained results demonstrate different properties of the correlated electrons systems that arise due to formation of Q-balls possessing internal bosonic frequency $\Omega=2\pi nT$ in Matsubara time and, thus, forming the quantum thermodynamic time polycrystals. Presented theory may give a clue concerning a possible mechanism of the experimentally measured properties of high-T$_c$ cuprates in the "strange metal" phase of their phase diagram. We believe , these results provide support to the quantum thermodynamic time crystal model of the Euclidean Q-balls considered in the present paper.

  We show that the quantum state of the emitted photons is non-classical and does depend on the QEW shape. This non-classicality originates from the shape dependent off-diagonal terms of the photon density matrix. Our findings indicate that in the case of a modulated density QEWs beam, the phase of the off-diagonal terms of the photon state emitted by the modulated QEWs is the harbinger of bunched beam superradiance.

  A quantum simulation of magnetism in trapped-ion systems makes use of the crystal vibrations to mediate pairwise interactions between spins. These interactions can be accounted for by a long-wavelength relativistic theory, where the phonons are described by a coarse-grained Klein-Gordon field. We show that thermal effects, which can be controlled by laser cooling, can unveil this flow through the appearance of thermal masses in interacting QFTs.
