Quantum vortex channels as Josephson junctions
Natalia Masalaeva, Wyatt Kirkby, Francesca Ferlaino +1
In quantum gases, weak links are typically realized with externally imposed optical potentials. We show that, in rotating binary condensates, quantized vortices in one component fo…
Rotational Superradiance in a Time-Reversal Symmetry-Broken Quantum Gas inside an Optical Cavity
Natalia Masalaeva, Farokh Mivehvar
Appearance of quantized vortices in a superfluid and a Bose-Einstein condensate (BEC) stems from their nontrivial response to broken time-reversal symmetry (TRS). Here we show that…
Measurement-assisted non-Gaussian gate for Schrödinger cat states preparation: Fock resource state versus cubic phase state
A. V. Baeva, N. G. Veselkova, N. I. Masalaeva +1
In this paper, we consider the preparation of Schrödinger cat states using a measurement-assisted gate based on the Fock resource state, the quantum non-demolition (QND) entangling…
Tuning photon-mediated interactions in a multimode cavity: from supersolid to insulating droplets hosting phononic excitations
Natalia Masalaeva, Helmut Ritsch, Farokh Mivehvar
Ultracold atoms trapped in laser-generated optical lattices serve as a versatile platform for quantum simulations. However, as these lattices are infinitely stiff, they do not allo…
Quantum statistics of Schrödinger cat states prepared by logical gate with non-Gaussian resource state
N. I. Masalaeva, I. V. Sokolov
A measurement-induced continuous-variable logical gate is able to prepare Schrödinger cat states if the gate uses a non-Gaussian resource state, such as cubic phase state [I. V. So…
Spin and density self-ordering in dynamic polarization gradients fields
Natalia Masalaeva, Wolfgang Niedenzu, Farokh Mivehvar +1
We study the zero-temperature quantum phase diagram for a two-component Bose-Einstein condensate in an optical cavity. The two atomic spin states are Raman coupled by two transvers…
Cavity-assisted squeezing and entanglement: Non-adiabatic effects and optimal cavity-atomic ensemble matching
N. I. Masalaeva, A. N. Vetlugin, I. V. Sokolov
We investigate theoretically quantum entanglement of light with the collective spin polarization of a cold atomic ensemble in cavity-assisted Raman schemes. Previous works concentr…
Cavity-assisted atomic Raman memories beyond the bad cavity limit: effect of four-wave mixing
N. G. Veselkova, N. I. Masalaeva, I. V. Sokolov
Quantum memories can be used not only for the storage of quantum information, but also for substantial manipulation of ensembles of quantum states. Therefore, the speed of such man…
Modified gravitational collapse, or the wonders of the MOND
Alexey Golovnev, Natalia Masalaeva
There are many hot discussions in the literature about two competing paradigms in galactic and extra-galactic astronomy and cosmology, namely the Dark Matter and the Modified Newto…
