Feshbach-Einstein Condensates [PDF]

open access: yesPhysical Review Letters, 2009
We investigate the phase diagram of a two-species Bose-Hubbard model describing atoms and molecules on a lattice, interacting via a Feshbach resonance. We identify a region where the system exhibits an exotic super-Mott phase and regions with phases characterized by atomic and/or molecular condensates.

Effects of Bose-Einstein Condensation on forces among bodies sitting in a boson heat bath [PDF]

open access: yes, 2000
We explore the consequences of Bose-Einstein condensation on two-scalar-exchange mediated forces among bodies that sit in a boson gas. We find that below the condensation temperature the range of the forces becomes infinite while it is finite at ...

Physics of $\pi$-Meson Condensation and High Temperature Cuprate Superconductors

open access: yes, 2009
The idea of condensation of the Goldstone $\pi$-meson field in nuclear matter had been put forward a long time ago. However, it was established that the normal nuclear density is too low, it is not sufficient to condensate $\pi$-mesons. This is why the $\

A third family of super dense stars in the presence of antikaon condensates [PDF]

open access: yes, 2001
The formation of $K^-$ and $\bar K^0$ condensation in $\beta$-equilibrated hyperonic matter is investigated within a relativistic mean field model. In this model, baryon-baryon and (anti)kaon-baryon interactions are mediated by the exchange of mesons. It

Selecting and Installing Energy-Efficient Windows to Improve Dwelling Sustainability

open access: yesVitruvio: International Journal of Architectural Technology and Sustainability, 2017
Windows play a significant role in achieving comfort in buildings by letting in natural light, solar warmth, fresh air and permitting outdoor views. On the other hand, poor quality windows can be the source of overheating or unwanted infiltration or ...

Spirocyclic Nitroxides as Versatile Tools in Modern Natural Sciences: From Synthesis to Applications. Part I. Old and New Synthetic Approaches to Spirocyclic Nitroxyl Radicals

open access: yesMolecules, 2021
Spirocyclic nitroxyl radicals (SNRs) are stable paramagnetics bearing spiro-junction at α-, β-, or γ-carbon atom of the nitroxide fragment, which is part of the heterocyclic system.

Entanglement phases as holographic duals of anyon condensates [PDF]

open access: yes, 2017
Anyon condensation forms a mechanism which allows to relate different topological phases. We study anyon condensation in the framework of Projected Entangled Pair States (PEPS) where topological order is characterized through local symmetries of the ...

A time-domain finite element model reduction method for viscoelastic linear and nonlinear systems

open access: yesLatin American Journal of Solids and Structures
Many authors have shown that the effective design of viscoelastic systems can be conveniently carried out by using modern mathematical models to represent the frequency- and temperature-dependent behavior of viscoelastic materials.
