Breathing Mode of a Bose-Einstein Condensate Immersed in a Fermi Sea
Piotr T. Grochowski, Tomasz Karpiuk, Mirosław Brewczyk +1
By analyzing breathing mode of a Bose-Einstein condensate repulsively interacting with a polarized fermionic cloud, we further the understanding of a Bose-Fermi mixture recently re…
Nanoscale phase separation and pseudogap in the hole-doped cuprates from fluctuating Cu-O-Cu bonds
Sergi Julià-Farré, Alexandre Dauphin, Ravindra W. Chhajlany +4
The pseudogap phenomenology is one of the enigmas of the physics of high-Tc superconductors. Many members of the cuprate family have now been characterized with high resolution in…
Collective oscillations of a two-component Fermi gas on the repulsive branch
Tomasz Karpiuk, Piotr T. Grochowski, Mirosław Brewczyk +1
We calculate frequencies of collective oscillations of two-component Fermi gas that is kept on the repulsive branch of its energy spectrum. Not only is a paramagnetic phase explore…
Two-mode Gaussian quantum states measured by collinearly and noncollinearly accelerating observers
Piotr T. Grochowski, Krzysztof Lorek, Andrzej Dragan
We generalize -dimensional formalism derived by Ahmadi et. al. [Phys. Rev. D \textbf{93}, 124031] to investigate an effect of relativistic acceleration on localized two-mode G…
Fermionic quantum carpets: From canals and ridges to solitonlike structures
Piotr T. Grochowski, Tomasz Karpiuk, Mirosław Brewczyk +1
We report a formation of sharp, solitonlike structures in an experimentally accessible ultracold Fermi gas, as a quantum carpet solution is analyzed in a many body system. The effe…
