Circular dichroism in resonant photoelectron diffraction as a direct probe of sublattice magnetization in altermagnets
Peter Krüger
Altermagnets are a new class of magnetic materials that are promising for spintronics technology. Here it is shown that in altermagnets, the circular dichroism (CD) in resonant pho…

Finite-size effects of the excess entropy computed from integrating the radial distribution function
Darshan Raju, Mahinder Ramdin, Jean-Marc Simon +2
Computation of the excess entropy from the second-order density expansion of the entropy holds strictly for infinite systems in the limit of small densities. For the reliable and e…

How to compute density fluctuations at the nanoscale
Peter Krüger
The standard definition of particle number fluctuations based on point-like particles neglects the excluded volume effect. This leads to a large and systematic finite-size scaling…
