Application of Instantons: Quenching of Macroscopic Quantum Coherence and Macroscopic Fermi-Particle Configurations [PDF]
, 1996 Starting from the coherent state representation of the evolution operator with the help of the path-integral, we derive a formula for the low-lying levels $E = \epsilon_0 - 2\triangle\epsilon cos (s+\xi)\pi$ of a quantum spin system.

Stable Macroscopic Quantum Superpositions [PDF]
Physical Review Letters, 2011 We study the stability of superpositions of macroscopically distinct quantum states under decoherence. We introduce a class of quantum states with entanglement features similar to Greenberger-Horne-Zeilinger (GHZ) states, but with an inherent stability against noise and decoherence.

Experimental Demonstration of Macroscopic Quantum Coherence in Gaussian States [PDF]
, 2007 We witness experimentally the presence of macroscopic coherence in Gaussian quantum states using a recently proposed criterion (E.G. Cavalcanti and M. Reid, Phys. Rev. Lett. 97, 170405 (2006)).

Macroscopic Models for Superconductivity [PDF]
SIAM Review, 1992 Summary: This paper reviews the derivation of some macroscopic models for superconductivity and also some of the mathematical challenges posed by these models. The paper begins by exploring certain analogies between phase changes in superconductors and those in soldification and melting.

A continuum model of gas flows with localized density variations [PDF]
, 2008 We discuss the kinetic representation of gases and the derivation of macroscopic equations governing the thermomechanical behavior of a dilute gas viewed at the macroscopic level as a continuous medium.

Proceedings of the National Academy of Sciences, 2009 In 2003 zoologists proposed a short, standardized DNA sequence from a uniform locality on the genome to serve as a DNA barcode to identify the species of tissue from almost all animals—reliably, quickly, and economically. In 2008 two New York City high school students, Kate Stoeckle and Louisa Strauss (1), used the accumulating barcode reference ...

Quantum Fisher information on its own is not a valid measure of the coherence
Results in Physics, 2018 We show that contrary to the claim in Feng and Wei (2017), the quantum Fisher information itself is not a valid measure of the coherence based on the resource theory because it can increase via an incoherent operation.
