Exact characterizations for quantum conditional mutual information and some other entropies
Zhou Gang
Lieb and Ruskai's strong subadditivity theorem, which shows that the conditional mutual information must be nonnegative, is fundamental in quantum theory. It has numerous applicati…
A Completion of Quantum Mechanics
Jürg Fröhlich, Zhou Gang, Alessandro Pizzo
A proposal of how to complete non-relativistic quantum mechanics to a physically meaningful, mathematically precise and logically coherent theory is reviewed. Our proposal leads to…
On the Evolution of States in a Quantum-Mechanical Model of Experiments
Jürg Fröhlich, Zhou Gang
The postulates of von Neumann and Lüders concerning measurements in quantum mechanics are discussed and criticized in the context of a simple model proposed by Gisin. The main purp…
Exponential Convergence to the Maxwell Distribution For Spatially Inhomogenous Boltzmann Equations
Zhou Gang
We consider the rate of convergence of solutions of spatially inhomogenous Boltzmann equations, with hard sphere potentials, to some equilibriums, called Maxwellians. Maxwellians a…
An Adiabatic Theorem for the Gross-Pitaevskii Equation
Zhou Gang, Philip Grech
We prove an adiabatic theorem for the non-autonomous Gross-Pitaevskii equation in the case of a weak trap. More precisely, we assume that the external potential decays suitably at…
Derivation of an effective evolution equation for a strongly coupled polaron
Rupert L. Frank, Zhou Gang
Fröhlich's polaron Hamiltonian describes an electron coupled to the quantized phonon field of an ionic crystal. We show that in the strong coupling limit the dynamics of the polaro…
Emission of Cherenkov Radiation as a Mechanism for Hamiltonian Friction
Juerg Froehlich, Zhou Gang
We study the motion of a heavy tracer particle weakly coupled to a dense, weakly interacting Bose gas exhibiting Bose-Einstein condensation. In the so-called mean-field limit, the…
