Bogoliubov theory of the Hawking effect in Bose-Einstein condensates [PDF]
arXiv, 2002 Artificial black holes may demonstrate some of the elusive quantum properties of the event horizon, in particular Hawking radiation. One promising candidate is a sonic hole in a Bose-Einstein condensate. We clarify why Hawking radiation emerges from the condensate and how this condensed-matter analog reflects some of the intriguing aspects of quantum ...

Nano Select, Volume 6, Issue 4, April 2025.XYFe4As4 samples were synthesized by the Flux Method and Solid‐State Reaction Method (SSR). The flux method is a viable method for synthesizing 1144‐type single‐crystalline FeBSCs that uses a molten metal salt, called flux, to dissolve precursor materials and promote crystal growth of the desired XYFe4As4 sample.

Thermodynamic QED Coherence in Condensed Matter: Microscopic Basis of Thermal Superradiance [PDF]
arXiv, 2002 Electromagnetic superradiant field coherence exists in a condensed matter system if the electromagnetic field oscillators undergo a mean displacement. Transitions into thermal states with ordered superradiant phases have been shown to theoretically exist in Dicke-Preparata models.

Bosonization and Duality in Condensed Matter Systems [PDF]
arXiv, 1995 We show that abelian bosonization of 1+1 dimensional fermion systems can be interpreted as duality transformation and, as a conseguence, it can be generalized to arbitrary dimensions in terms of gauge forms of rank $d-1$, where $d$ is the dimension of the space. This permit to treat condensed matter systems in $d>1$ as gauge theories.

Small Science, Volume 5, Issue 4, April 2025.MXenes are two‐dimensional materials with unique properties like high conductivity and potential for surface functionalization. This review focuses on their synthesis through top‐down and bottom‐up methods and their biomedical applications, including photodynamic therapy and photothermal therapy.

Qualitative methods in condensed matter physics [PDF]
arXiv, 2019 Expanding on our former hypothesis that, in the current information age, teaching physics should become more intuition-based and aiming at pattern recognition skills, we present multiple examples of qualitative methods in condensed matter physics.

Kinetic effects of multi-component nucleation [PDF]
arXiv, 2003 The process of multicomponent condensation is considered. The theory taking into account several channels of nucleation is constructed. The analytical approximate description of the whole condensation process is given. The specific phenomena of the secondary nucleation is described analytically.

Comment on ``Ramsey Fringes in a Bose-Einstein Condensate between Atoms and Molecules'' [PDF]
arXiv, 2003 In Phys. Rev. Lett. 89, 180401 (2002) [cond-mat/0204504], Kokkelmans and Holland interpret the results of a recent experiment at JILA that demonstrated atom-molecule coherence in a Bose-Einstein condensate. Using a mean-field approximation to a resonance field theory involving an atom condensate and a molecular condensate, they find that the molecular ...

The $K^0$ condensed phase of color-flavor locked quark matter : its formation as a stable state reexamined [PDF]
arXiv, 2005 Taking the vector kaon-quark interaction into account, we reexamine in detail the neutral kaon condensation in color-flavor locked quark matter. It is found that the pairing phenomena in the quark matter are somewhat influenced by $K^0$ condensation. Different from the previous predictions, we find that the $K^0$ condensed phase might no longer be more
