Hybrid exciton-polaritons in a bad microcavity containing the organic and inorganic quantum wells
We study the hybrid exciton-polaritons in a bad microcavity containing the
organic and inorganic quantum wells. The corresponding polariton states are
given. The analytical solution and the numerical result of the stationary
spectrum for the cavity field are finishedComment: 3 pages, 1 figure. appear in Communications in Theoretical Physic
Interface-Controlled Ferroelectricity at the Nanoscale
Recent experimental results demonstrate that in thin films ferroelectricity
persists down to film thickness of a few unit cells. This finding opens an
avenue for novel electronic devices based on ultathin ferroelectrics, but also
raises questions about factors controlling ferroelectricity and the nature of
the ferroelectric state at the nanoscale. Here we report a first-principles
study of KNbO3 ferroelectric thin films placed between two metal electrodes,
either SrRuO3 or Pt. We show that the bonding at the ferroelectric-metal
interface imposes severe constraints on the displacement of atoms, destroying
the bulk tetragonal soft mode in thin ferroelectric films. This does not,
however, quench local polarization. If the interface bonding is sufficiently
strong the ground state represents a ferroelectric double-domain structure,
driven by the intrinsic oppositely-oriented dipole moments at the two
interfaces. Although the critical thickness for the net polarization of KNbO3
film is finite - about 1 nm for Pt and 1.8 nm for SrRuO3 electrodes - local
polarization persists down to thickness of a unit cell.Comment: 5 pages, 4 figure

Bending and wrinkling as competing relaxation pathways for strained free-hanging films
An equilibrium phase diagram for the shape of compressively strained
free-hanging films is developed by total strain energy minimization. For small
strain gradients {\Delta}{\epsilon}, the film wrinkles, while for sufficiently
large {\Delta}{\epsilon}, a phase transition from wrinkling to bending occurs.
We consider competing relaxation mechanisms for free-hanging films, which have
rolled up into tube structures, and we provide an upper limit for the maximum
achievable number of tube rotations.Comment: 4 pages, 4 figure
Entangling two superconducting LC coherent modes via a superconducting flux qubit
Based on a pure solid-state device consisting of two superconducting LC
circuits coupled to a superconducting flux qubit, we propose in this paper that
the maximally entangled coherent states of the two LC modes can be generated
for arbitrary coherent states through flux qubit controls.Comment: 5 pages, 2 figure
A scheme for dense coding in the non-symmetric quantum channel
We investigate the dense coding in the case of non-symmetric Hilbert spaces
of the sender and receiver's particles sharing the quantum maximally entangled
state. The efficiency of classical information gain is also considered. We
conclude that when a more level particle is with the sender, she can get a
non-symmetric quantum channel from a symmetric one by entanglement transfer.
Thus the efficiency of information transmission is improved

Identification of novel transcripts and peptides in developing murine lens.
We previously investigated the transcriptome and proteome profiles of the murine ocular lens at six developmental time points including two embryonic (E15 and E18) and four postnatal time points (P0, P3, P6, and P9). Here, we extend our analyses to identify novel transcripts and peptides in developing mouse lens. We identified a total of 9,707 novel transcripts and 325 novel fusion genes in developing mouse lens. Additionally, we identified 13,281 novel alternative splicing (AS) events in mouse lens including 6,990 exon skipping (ES), 2,447 alternative 3' splice site (A3SS), 1,900 alternative 5' splice site (A5SS), 1,771 mutually exclusive exons (MXE), and 173 intron retention (IR). Finally, we integrated our OMIC (Transcriptome and Proteome) datasets identifying 20 novel peptides in mouse lens. All 20 peptides were validated through matching MS/MS spectra of synthetic peptides. To the best of our knowledge, this is the first report integrating OMIC datasets to identify novel peptides in developing murine lens
