    In general relativity producing a regular bounce entails violation of Null Energy Condition for a dynamical source in the model.
    That generically indicates existence of ghosts or other instabilities.
    However, in cuscuton modification of gravity, the correspondence between a background bounce and violation of Null Energy Condition for dynamical sources is broken.
    Cuscuton action, modifies...

  2. 2858. Qubits as edge state detectors: illustration using the SSH model

    Theoretical Physics / Physique théorique (DTP-DPT)
    Invited Speaker / Conférencier(ère) invité(e)

    As is well-known, qubits are the fundamental building blocks of quantum computers, and more generally, of quantum information. A major challenge in the development of quantum devices arises because the information content in any quantum state is rather fragile, as no system is completely isolated from its environment; generally, such interactions degrade the quantum state, resulting in a loss...

  3. 2393. An Analytic Study of the Fourier Transform of the Gravitational Wave Pulsar Signal with Spin-down Effects

    Oral (Non-Student) / Orale (non-étudiant(e))

    The direct detection of gravitational waves from pulsars is a much anticipated discovery in the emerging field of multi-messenger gravitational wave (GW) astronomy. In this context we develop an analytic approach to study the Fourier Transform (FT) of the GW pulsar signal including spindown effects. To incorporate the spindown effects, we incorporate an extended model of Alvarez and...

  4. 2399. Double Spectrum Digraph of Quantum Group Gravity
    Prof. zhi-an luan (china petroleum university, huadong)

    Theoretical Physics / Physique théorique (DTP-DPT)
    Oral (Non-Student) / Orale (non-étudiant(e))

    We establish the unitary representation theory of quantum group gravity.
    (i) A dual pair of nonlinear diffusion equations are presented, first describes the growth phase transition process (as universe expansion); second describes the descent process (as Hall effect). These exactly analytical solutions explain the explicate and implicate physical causality, structure and law of dual quantum...
