Most efficient type of heat pump it's a fake. Not even Maxwell's daemon can beat the second law. |

Most efficient type of heat pump If we assume that the second law is true (which all patent examiners do) then it is not possible to beat the Carnot efficiency. |

Query about Bernoulli's principle That the gravitational effect is unnotable is your mistake. It is exactly gravity which counteracts the gradient in pressure. |

Factors of $c$ in the Hamiltonian for a charged particle in electromagnetic field The first is the expression in the SI units (which most modern books are written in). The second is the expression in Gauss units (which still most scientific literature and old books use). |

Flux quantization and AB effect and Laughlin's argument of IQHE Because the charge is quantized in units of $e$. If you write down the Schrödinger equation for this problem, you will notice that you can gauge away full (and only full) flux quanta. |

Flux quantization and AB effect and Laughlin's argument of IQHE Laughlin says nothing about quantization. In fact any flux is allowed inside the cylinder. What he need however, is that an equivalent of a full flux quantum has no effect on the physics in the system. |

Quantum mechanical angular momentum and spin formalism/notation A direct sum $H=V_1 \oplus V_2$ is nothing but a statement that the Hilberspace $H$ consists of $V_1$ and $V_2$, i.e., a basis in $H$ is the combined basis of $V_1$ and $V_2$. |

Thermal equilibrium and non correlations @VijayMurthy: why should it follow from the Bohr-van Leeuwen theorem that the position and the canonical momentum are not correlated??? |

Lennard Jones liquid vapour phase transition if you would give all the parameters (the parameters of the Lennard Jones, which pressure, which temperature) in the question then maybe somebody can help. |

Thermal equilibrium and non correlations I think you are right. You could study the case of a non separable Hamiltonian (particle in a constant magnetic field) and you (obviously) will find correlations. |
