On the excursion theory for linear diffusions
Paavo Salminen, Pierre Vallois, Marc Yor
We present a number of important identities related to the excursion theory of linear diffusions. In particular, excursions straddling an independent exponential time are studied i…

Impurity induced spin texture in quantum critical 2D antiferromagnets
Kaj H. Hoglund, Anders W. Sandvik, Subir Sachdev
We describe the uniform and staggered magnetization distributions around a vacancy in a quantum critical two-dimensional S=1/2 antiferromagnet. The distributions are delocalized ac…
