Singular Mean-Field States: A Brief Review of Recent Results
Condensed Matter, 2020 This article provides a focused review of recent findings which demonstrate, in some cases quite counter-intuitively, the existence of bound states with a singularity of the density pattern at the center; the states are physically meaningful because ...

Magnetic Excitations in the Ground State of $\mathrm{Yb_2Ti_2O_7}$ [PDF]
, 2017 We report an extensive study on the zero field ground state of a powder sample of the pyrochlore $\mathrm{Yb_2Ti_2O_7}$. A sharp heat capacity anomaly that labels a low temperature phase transition in this material is observed at 280 mK.

Moving Toward the Ground State [PDF]
Cell Stem Cell, 2015 Transferring mouse ESCs to a media supplemented with Mek and Gsk3β inhibitors (2i) provokes marked transcriptional and epigenetic changes, embodying a shift toward ground-state pluripotency. In this issue of Cell Stem Cell, Kolodziejczyk et al. (2015) examine population structures of ESCs while Galonska et al.

Extended RPA with ground-state correlations in a solvable model [PDF]
Phys.Rev. C70 (2004) 057307, 2004 The ground states and excited states of the Lipkin model hamiltonian are calculated using a new theoretical approach which has been derived from an extended time-dependent Hartree-Fock theory known as the time-dependent density-matrix theory (TDDM). TDDM enables us to calculate correlated ground states, and its small amplitude limit (STDDM), which is a

The role of Ta on twinnability in nanocrystalline Cu–Ta alloys
Materials Research Letters, 2017 Nanostructured Cu–Ta alloys show promise as high-strength materials in part due to their limited grain growth. In the present study, we elucidate the role of Ta on the transition from deformation twinning to dislocation-mediated slip mechanisms in ...
