We describe boson sampling of interacting atoms from the noncondensed fraction of Bose–Einstein-condensed (BEC) gas confined in a box trap as a new platform for studying computational ♯P-hardness and quantum supremacy of many-body systems. We cal

We present a finite-order system of recurrence relations for a permanent of circulant matrices containing a band of k any-value diagonals on top of a uniform matrix (for k = 1, 2, and 3) as well as the method for deriving such recurrence relations wh

Numerical simulations and qualitative analysis of the predicted simultaneous generation of different quasiperiodic pulse trains [1] - [3] in a CW multimode class C quantum-dot heterolaser with self-locking of some of the modes are carried out on the

We carry out numerical modelling of the Maxwell-Bloch equations for a CW superradiant lasing of a homogeneous two-level active medium in a symmetric low-Q Fabry-Perot cavity and find a remarkable phase transition. Namely, at a pumping level n > n ( a

Numerical analysis of the Maxwell-Bloch equations for a low-Q CW superradiant laser with symmetric Fabry-Perot cavity shows that a strong pumping leads to spontaneous formation of a highly asymmetric half-wavelength grating of polarization and popula

We propose an analytical model for a distributed current sheet separating two regions of anisotropic collisionless plasma with different values of magnetization and different effective temperatures of the energy distributions of electrons and ions [1

We calculate the Bose-Einstein condensate (BEC) occupation statistics vs. the interparticle interaction in a dilute gas with a nonuniform condensate in a box trap within the Bogoliubov approach. The results are compared against the previously found B

We communicate three formulas for the permanents of degenerate Schur and circulant matrices. These combinatorial and integral formulas are intended for the analytical and asymptotic evaluation of the permanents as well as for the solution of three-di
