Abstract: We present a detailed study of the behavior of the delocalization properties in the phase space of the Husimi function of ground and excited states in the avoided crossings vicinity for a Hamiltonian of Lipkin–Meshkov–Glick… read more here.

DOI: 10.1103/physrevlett.125.151101
Abstract: We constrain the parameters of neutron superfluidity in the cores of neutron stars making use of the recently proposed effect of resonance stabilization of r modes. To this end, we, for the first time, calculate… read more here.

DOI: 10.1126/sciadv.abl3708
Abstract: Signal amplification by reversible exchange (SABRE) creates “hyperpolarization” (large spin magnetization) using a transition metal catalyst and parahydrogen, addressing the sensitivity limitations of magnetic resonance. SABRE and its heteronuclear variant X-SABRE are simple, fast, and… read more here.

DOI: 10.3390/e25050751
Abstract: Electronic structure theory describes the properties of solids using Bloch states that correspond to highly symmetrical nuclear configurations. However, nuclear thermal motion destroys translation symmetry. Here, we describe two approaches relevant to the time evolution… read more here.
