Macroscopic quantum condensate in the many body systems

Макроскопические квантовые конденсаты в системах многих тел
In particular, modern photonics investigates the possibility of quantum tomography, which allows determining the phase coefficients of coherent light beams quantum superposition (photonic analogue of Schrodinger’s cat). The development of measurement techniques of quantum entanglement of photons lies in the basis of quantum information transmission devices construction. At the same time, the evidences of so called hidden order parameter high-temperature superconducting cuprates. This order parameter makes itself evident in appearance of the gap on electronic spectrum on Fermi level, however cannot be determined directly, as it can be done with usual order parameters: magnetization or the density of charge density wave. New theoretical results, obtained in the Department of Theoretical Physics and Quantum Technologies indicates, that realization of ordering (“condensation” of order parameter) in the form of the quantum superposition of quasiclassical states of photons or electrons can be expressed with the language of crystallization in euclidean space. Here in “euclidian crystal” unlike it happens in the usual crystal, ordering takes place along the imaginary “Matsubara time” axis instead of the space axes. “Matsubara time” appears in the thermodynamicall description of quantum systems. At the current moment the researches are dedicated to the development of the “Theory of Elasticity” of euclidian crystals and their interaction with the external world are performed in the department.
