Compass models: Theory and physical motivations
... We start by introducing and defining, in Sec. II, various compass models. Next, in Sec. III, we discuss viable extensions of more typical compass models including, e.g., ring exchange and extensions to general spatial dimensions. While the most common representation of compass models is that on a la ...

Quantum Orders and Symmetric Spin Liquids

However, the hypothesis of internal “patterns” appears to have one difficulty – FQH states are liquids, and how can liquids have any ...

An Unshunted Comparator as a Device for Quantum Measurements
... During the double-pulse the phase over the comparator increases by 4π. This implies that an anti-pulse is created in the input line and this anti-pulse will then propagate away from the comparator back into the input line. This suggests a new SFQ comparator design where the detection or non-detectio ...

Relativistic effects in atomic and molecular properties

Until the seventies of the 20th century it was generally accepted that for a description of the electronic structure of atoms and molecules and, therefore, for the whole chemistry and for the substantial part of physics, relativistic theory is not needed. According to Sheldon L. Glashow [1], Nobel P ...
