Cavity Casimir-Polder Forces and Their Effects in Ground-State Chemical Reactivity [PDF]
Physical Review X, 2018 Here we present a fundamental study on how the ground-state chemical reactivity of a molecule can be modified in a QED scenario, i.e., when it is placed inside a cavity and there is strong coupling between the cavity field and vibrational modes within ...

Photodetachment of C− in the ground state
Journal of Physics: Conference Series, 2020 Synopsis Absolute total cross sections and asymmetry parameters for photodetachment of C− (4So) have been measured using animated-crossed-beam and velocity map imaging techniques, for photon energies from threshold up to 6eV. The cross sections are 15% to 25% larger than earlier experimental results above 2.2 eV.

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 ...

Experimental signatures of spin superfluid ground state in canted antiferromagnet Cr2O3 via nonlocal spin transport [PDF]
Science Advances, 2018 We report direct experimental signatures for the spin superfluid ground state in canted antiferromagnets via nonlocal spin transport. Spin superfluid is a novel emerging quantum matter arising from the Bose-Einstein condensate (BEC) of spin-1 bosons.

Probing the superconducting ground state of the rare-earth ternary boride superconductors $R$RuB$_2$ ($R$ = Lu,Y) using muon-spin rotation and relaxation [PDF]
, 2018 The superconductivity in the rare-earth transition metal ternary borides $R$RuB$_2$ (where $R$ = Lu and Y) has been investigated using muon-spin rotation and relaxation.

The Journal of Chemical Physics, 1998 The uncertainty over the symmetry of the ground state of NiH2 is resolved, showing that it is a bent 1A1. The computations have been performed using a complete active space self-consistent field wave function (CASSCF), a second order perturbation method (CASPT2), and quasirelativistic corrections to the energy and geometry.

NLS ground states on graphs [PDF]
Calculus of Variations and Partial Differential Equations, 2014 We investigate the existence of ground states for the subcritical NLS energy on metric graphs. In particular, we find out a topological assumption that guarantees the nonexistence of ground states, and give an example in which the assumption is not fulfilled and ground states actually exist.

Gaussian-Based Coupled-Cluster Theory for the Ground-State and Band Structure of Solids. [PDF]
Journal of Chemical Theory and Computation, 2017 We present the results of Gaussian-based ground-state and excited-state equation-of-motion coupled-cluster theory with single and double excitations for three-dimensional solids.
