Bose-Einstein Condensation in Financial Systems

Nonlinear Analysis, 2005
We describe financial systems as condensates, similar to Bose-Einstein condensates, and calculate equilibrium statistical distributions following from the model.

Ideal Bose Gas in Higher Dimensions [PDF]

مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2008
Some physical properties of the behavior of an ideal non- relativistic Bose gas in N – dimensional space are theoretically investigated. The general analytic expressions of the critical temperature Tc of Bose – Einstein condensation, and the high ...

Emergent Magnetism, Heavy Electrons, and Pressure‐Induced Reentrant Superconductivity in the Iron Substituted 4d Transition‐Metal Sulfides

Advanced Science, EarlyView.
This work illustrates that magnetic Fe substitution enables systematic modulation of physical properties of the putative unconventional superconductor Rh17S15. Iron doping uncovers delicate competition between weak ferromagnetism, spin‐glass states, heavy‐fermion signatures, and superconductivity.

On the dynamics of cosmological phase transition during Bose–Einstein condensation of dark matter in Barrow entropy-based cosmology

European Physical Journal C: Particles and Fields
Throughout the cosmic evolution of the Universe, when the temperature of a boson gas drops below a certain threshold, the Bose–Einstein condensation phenomenon may occur.

Pure Inverse Spin Hall Effect in Ferromagnetic Ni80Fe20/Y3Fe5O12 (YIG) Heterostructures via the Longitudinal Spin Seebeck Effect

Advanced Physics Research, EarlyView.
A pure inverse spin Hall effect (ISHE) is demonstrated in ferromagnetic Ni₈₀Fe2₀/YIG heterostructures via the longitudinal spin Seebeck effect. By employing symmetry‐controlled geometries and reference samples, anomalous Nernst contributions are quantitatively eliminated, revealing intrinsic spin–charge conversion in Ni₈₀Fe2₀.

Dynamics of cosmological phase crossover during Bose–Einstein condensation of dark matter in Tsallis cosmology

European Physical Journal C: Particles and Fields
During the cosmic evolution process, as the temperature of a cosmological boson gas falls below a certain threshold, a Bose–Einstein condensation process can occur at various points throughout the cosmic history of the Universe.

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Electromagnetic quantum shifts in relativistic Bose-Einstein condensation

Physics Letters B, 2021
We compute deviations from ideal gas behavior of the pressure, density, and Bose-Einstein condensation temperature of a relativistic gas of charged scalar bosons caused by the current-current interaction induced by electromagnetic quantum fluctuations ...

Skyrmions in Scalar Fields of Non‐Hermitian Optical Microcavities: Spontaneous Formation, Nonlinear Control, and Optical Forces

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
Skyrmion topology is shown to emerge spontaneously in scalar fields of driven‐dissipative optical microcavities, without externally imposed phase structure. In exciton‐polariton condensates, non‐Hermitian flow generates isolated Skyrmions and self‐organized Skyrmion lattices, while optical nonlinearities enable switching and reconfiguration of their ...

Bose condensation in (random) traps

Condensed Matter Physics, 2009
We study a non-interacting (perfect) Bose-gas in random external potentials (traps). It is shown that a generalized Bose-Einstein condensation in the random eigenstates manifests if and only if the same occurs in the one-particle kinetic-energy ...
