Density Induced Phase Transitions in the Schwinger Model: A Study with Matrix Product States [PDF]
, 2017 We numerically study the zero temperature phase structure of the multiflavor Schwinger model at nonzero chemical potential. Using matrix product states, we reproduce analytical results for the phase structure for two flavors in the massless case and ...

CHEMICAL STRUCTURE OF STREPTOTHRICINS
The Journal of Antibiotics, 1972 The general formula, proposed earlier for the natural streptothricins E, D, C, B, A and for the biosynthetic streptothricin X was shown to be valid. 1. The presence of a common moiety in streptothricins F, E, D, C, B and A was demonstrated by isolation of N-guan-streptolidyl gulosaminide from preparations of all these antibiotics. 2.

The observed chemical structure of L1544
, 2017 Prior to star formation, pre-stellar cores accumulate matter towards the centre. As a consequence, their central density increases while the temperature decreases. Understanding the evolution of the chemistry and physics in this early phase is crucial to
