Free expansion of fermionic dark solitons in a boson-fermion mixture

, 2005
We use a time-dependent dynamical mean-field-hydrodynamic model to study the formation of fermionic dark solitons in a trapped degenerate fermi gas mixed with a Bose-Einstein condensate in a harmonic as well as a periodic optical-lattice potential.

Group versus individual professional antenatal breastfeeding education for extending breastfeeding duration and exclusivity [PDF]

, 2015
Although breastfeeding initiation rates have increased substantially in many developed countries over the past several decades, breastfeeding duration and exclusivity remain suboptimal.

Instability of nonminimally coupled scalar fields in the spacetime of slowly rotating compact objects [PDF]

, 2014
Nonminimally coupled free scalar fields may be unstable in the spacetime of compact objects. Such instability can be triggered by classical seeds or, more simply, by quantum fluctuations giving rise to the so-called {\em vacuum awakening effect}.

Simulations of Alice Electrodynamics on a Lattice [PDF]

, 2002
In this paper we present results of numerical simulations and some (analytical) approximations of a compact $U(1)\ltimes\ZZ_2$ lattice gauge theory, including an extra bare mass term for Alice fluxes.

Insights Into Symmetry and Substitution Patterns Governing Singlet–Triplet Energy Gap in the Chemical Space of Azaphenalenes

Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
ABSTRACT Molecules that violate Hund's rule by exhibiting an inverted singlet–triplet gap (STG), where the first excited singlet (S1${\rm S}_1$) lies below the triplet (T1${\rm T}_1$), are rare but hold great promise as efficient fifth‐generation light emitters.

Possibility of "magic" co-trapping of two atomic species in optical lattices

, 2010
Much effort has been devoted to removing differential Stark shifts for atoms trapped in specially tailored "magic" optical lattices, but thus far work has focused on a single trapped atomic species.

Gravitational couplings of charged leptons in a medium [PDF]

, 2001
We calculate the leading order matter-induced corrections to the gravitational interactions of charged leptons and their antiparticles in a medium that contains electrons but not the other charged leptons, such as normal matter.

Development of an Organic Emitter Exhibiting Reverse Intersystem Crossing Faster than Intersystem Crossing

Angewandte Chemie, Volume 136, Issue 35, August 26, 2024.
The inverted singlet‐triplet excited states (iST) molecule, A6AP‐Cz, based on asymmetric hexa‐azaphenalene was designed. A6AP‐Cz showed the extremely short lifetime of delayed fluorescence (τDF) of 54 ns. Moreover, the reverse intersystem crossing (rate constant of RISC: kRISC=1.9×107 s−1) was faster than ISC (rate constant of ISC: kISC=1.0×107 s−1 ...

You Can't Get Through Szekeres Wormholes - or - Regularity, Topology and Causality in Quasi-Spherical Szekeres Models

, 2002
The spherically symmetric dust model of Lemaitre-Tolman can describe wormholes, but the causal communication between the two asymptotic regions through the neck is even less than in the vacuum (Schwarzschild-Kruskal-Szekeres) case.

Electric dipole moment constraints on minimal electroweak baryogenesis [PDF]

, 2006
We study the simplest generic extension of the Standard Model which allows for conventional electroweak baryogenesis, through the addition of dimension six operators in the Higgs sector.
