Thermodynamics of SU(2) bosons in one dimension

On the basis of Bethe ansatz solution of two-component bosons with SU(2) symmetry and $\delta$-function interaction in one dimension, we study the thermodynamics of the system at finite temperature by using the strategy of thermodynamic Bethe ansatz (TBA). It is shown that the ground state is an isospin "ferromagnetic" state by the method of TBA, and at high temperature the magnetic property is dominated by Curie's law. We obtain the exact result of specific heat and entropy in strong coupling limit which scales like $T$ at low temperature. While in weak coupling limit, it is found there is still no Bose-Einstein Condensation (BEC) in such 1D system.Comment: 7 page

Diaqua­bis­(4-hy­droxy-5-nitro­pyridine-2-carboxyl­ato-κ2 N 1,O 2)copper(II)

In the title compound, [Cu(C6H3N2O5)2(H2O)2], the CuII ion, lying on an inversion center, is coordinated by two pyridine N atoms and two carboxyl­ate O atoms from symmetry-related two 4-hy­droxy-5-nitro­pyridine-2-carboxyl­ate ligands, and two water mol­ecules, forming a distorted octa­hedral geometry. In the crystal, O—H⋯O hydrogen bonds link the complex mol­ecules. One of the H atoms of the water mol­ecule is disordered over two sites of equal occupancy

A Survey of Blockchain Applications in Different Domains

Blockchains have received much attention recently since they provide decentralized approaches to the creation and management of value. Many banks, Internet companies, car manufacturers, and even governments worldwide have incorporated or started considering blockchains to improve the security, scalability, and efficiency of their services. In this paper, we survey blockchain applications in different areas. These areas include cryptocurrency, healthcare, advertising, insurance, copyright protection, energy, and societal applications. Our work provides a timely summary for individuals and organizations interested in blockchains. We envision our study to motivate more blockchain applications.Comment: Published in Proceedings of the 2018 International Conference on Blockchain Technology and Application (ICBTA
