A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics
Natural Sciences, Volume 6, Issue 3, July 2026.ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at

Bose-Einstein Condensation in a Plasmonic Lattice
, 2017 Bose-Einstein condensation is a remarkable manifestation of quantum statistics and macroscopic quantum coherence. Superconductivity and superfluidity have their origin in Bose-Einstein condensation. Ultracold quantum gases have provided condensates close

European Physical Journal C: Particles and FieldsDuring 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.

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 ...

Magnetically Decoupled Janus Bound States in the Continuum for Chirality–Topology Control
Nanophotonics, Volume 15, Issue 11, 13 June 2026.This article demonstrates the Janus BICs, which are bi‐layer photonic crystal (PhCs) structures composed of C3v and magneto‐optical C6v symmetry slabs. It offers a unique platform for independent controlling chirality and topological charge, which successfully realizes the decoupling of topological charge and chirality.

Deriving density-matrix functionals for excited states
SciPost Physics, 2023 We initiate the recently proposed $w$-ensemble one-particle reduced density matrix functional theory ($w$-RDMFT) by deriving the first functional approximations and illustrate how excitation energies can be calculated in practice.

Soliton diffusion in a Bose-Einstein condensate: A signature of the analogue Hawking radiation
Physics Letters B, 2019 The analog Hawking radiation (HR) emanating from a sonic black hole horizon formed in a cigar-shaped Bose-Einstein condensate (BEC) at finite temperature is investigated. In particular, we study the effect of HR on a dark (topological) soliton.

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 ...
