Quantum conjugacy classes of simple matrix groups

A. Mudrov

Let be a simple complex classical group and $\g$ its Lie algebra. Let $\U_\hbar(\g)$ be the Drinfeld-Jimbo quantization of the universal enveloping algebra $\U(\g)$. We constru…

Estimation of pure qubits on circles

Samuel L. Braunstein, Sibasish Ghosh, Simone Severini

Gisin and Popescu [PRL, 83, 432 (1999)] have shown that more information about their direction can be obtained from a pair of anti-parallel spins compared to a pair of parallel spi…

Image states in metal clusters

Patrick Rinke, Kris Delaney, P. Garcia-Gonzalez +1

The existence of image states in small clusters is shown, using a quantum-mechanical many-body approach. We present image state energies and wave functions for spherical jellium cl…

Quantum Energy Inequalities in two-dimensional conformal field theory

Christopher J. Fewster, Stefan Hollands

Quantum energy inequalities (QEIs) are state-independent lower bounds on weighted averages of the stress-energy tensor, and have been established for several free quantum field mod…

p-Nuclearity in a New Perspective

Christopher J. Fewster, Izumi Ojima, Martin Porrmann

In this paper we try to settle some confused points concerning the use of the notion of p-nuclearity in the mathematical and physical literature, pointing out that the nuclearity i…

A Mass Transference Principle and the Duffin-Schaeffer conjecture for Hausdorff measures

Victor Beresnevich, Sanju Velani

A Hausdorff measure version of the Duffin-Schaeffer conjecture in metric number theory is introduced and discussed. The general conjecture is established modulo the original conjec…
