DOI: 10.1103/physreva.103.022822
Abstract: We study the prospects of using the electric quadrupole transitions from the ground states of Cu, Ag, and Au to the metastable states $^{2}D_{5/2}$ as clock transitions in optical lattice clocks. We calculate lifetimes, transition… read more here.

DOI: 10.1103/physrevb.103.024203
Abstract: We have recently shown that the logarithmic growth of the entanglement entropy following a quantum quench in a many-body localized phase is accompanied by a slow growth of the number entropy ${S}_{N}\ensuremath{\sim}ln\phantom{\rule{0.16em}{0ex}}ln\phantom{\rule{0.16em}{0ex}}t$. Here we provide… read more here.

DOI: 10.1103/physrevb.103.075418
Abstract: The interaction energy of the indirect-exchange or Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between magnetic spins localized on lattice sites of the $\ensuremath{\alpha}\text{\ensuremath{-}}{\mathcal{T}}_{3}$ model is calculated using linear response theory. In this model, the AB-honeycomb lattice structure is… read more here.

DOI: 10.1103/physrevc.101.034307
Abstract: The Royer formulas are often used to calculate the $\ensuremath{\alpha}$-decay half-lives [G. Royer, J. Phys. G 26, 1149 (2000); Nucl. Phys. A 848, 279 (2010)]. In recent years, the amount of experimental data on $\ensuremath{\alpha}$… read more here.

DOI: 10.1103/physrevc.101.044304
Abstract: We investigate the influence of a monochromatic strong laser electromagnetic field on $\ensuremath{\alpha}$ clustering and emission, by analyzing the Fourier components of the time-dependent $\ensuremath{\alpha}$-core realistic potential in the Henneberger representation. It turns out that… read more here.

DOI: 10.1103/physrevc.104.034302
Abstract: Shell structure effects on $\ensuremath{\alpha}$-cluster formation and decay are studied by using the quartetting wave function approach (QWFA). Both the intrinsic and center-of-mass (c.o.m.) motions of an $\ensuremath{\alpha}$ cluster inside a core nucleus are investigated… read more here.

Abstract: Background: Light ($30\ensuremath{\le}Z\ensuremath{\le}45$) neutron-rich isotopes are thought to be synthesized in the neutrino-driven ejecta of core-collapse supernovae explosions via the weak $r$ process. Recent nucleosynthesis studies have demonstrated that $(\ensuremath{\alpha},xn)$ reactions play a particularly important… read more here.
