Quantum States of Neutrons in the Gravitational Field
... What is gravity? In many respects this may be one of the most important questions ever asked. Answers to it have always been milestones on the way from ancient natural philosophy to modern science. Every physicist knows the legendary free fall experiments of Galileo Galilei at the dawn of empiricism ...

This metal-insulator transition should be directly observable in such a fractional quantum Hall effect line contact. In this paper we describe in detail the experimental signature of a 1D metal-insulator transition f ...

Fractional excitations in the square lattice quantum antiferromagnet
... In order to explore whether fractionalization of magnons can account for the (π, 0) anomaly in the QSLHAF, we use a theoretical approach based on Gutzwiller-projected variational wave functions [48, 49]. In this approach, spin operators are transformed into pairs of S = 1/2 fermionic operators so th ...

The Unruh effect revisited - Department of Mathematics and Statistics
... What is nevertheless still surprising in connection with the Unruh effect is the claim that the detector “perceives” a thermal distribution of radiation at some particular temperature that only depends on the acceleration. To see what is precisely meant by these statements, it is helpful to get rid ...
