9. Prepotential approach: A unified approach to exactly,quasi-exactly,and rationally extended solvable quantal systems

何 俊麟 (淡江大學)

29/06/2019, 16:00

We would like to demonstrate how all the known 1D exactly solvable, quasi-exactly solvable, and the recently discovered rationally extended solvable potentials, including those related to the exceptional orthogonal polynomials, can be constructed in a direct and systematic way, which we called the prepotential approach. In this approach, the prepotential, the deforming function, the potential,...

11. A possible connection of the broken power law between electron- and proton- spectra

Prof. 阮 建红 (East China Normal University)

29/06/2019, 17:00

Using the gluon condensation (GC) model, we predict a possible connection between the energy spectra of electron and proton. When GC occuring, large amount of gluons accumulate near the GC threshold, this phenomenon provides a possible source of the power rule broken in the energy spectra of cosmic rays, and also it predicts the connections between them.

12. Neutron star configurations confronting dark matter and neutron lifetime anomaly

楊 家威 (台灣師範大學)

The nature of dark matter (DM) has been one of major problems in physic. The stability and abundance of dark matter suggest possibility that the DM may play an important role for compact stellar objects. Confronting the recent neutron lifetime anomaly measurement in laboratories in Beam experiments and Bottle experiments. We propose the neutron decays into a DM and a new scalar boson to...

21. Charge Emission from Charged Black Holes

陳 江梅 (台灣中央大學)

30/06/2019, 16:00

The spontaneous pair production of charged scalars from near-extremal rotating, electrically and/or magnetically charged black holes is discussed. Analytical expressions for pair production, vacuum persistence and absorption cross section are found, and the spectral distribution is given a thermal interpretation. The associated holographical correspondence is confirmed at the 2-point function...

23. Thermodynamical study on universal horizons in higher $D$-dimensional spacetime and aether waves

丁 持坤 (湖南人文科技学院)

30/06/2019, 16:30

We investigate behaviors of the $D$-dimensional gravity coupled to a dynamical unit timelike vector, the aether, present two kinds of exact charged solutions and study the linearized wave spectrum of this theory. There is an universal horizon behind the Killing horizon in these aether black holes. We find that in the uncharged case, one can construct a Smarr formula and the (slightly modified)...

24. Positivity bounds in effective field theories

周 双勇 (ICTS, USTC)

30/06/2019, 17:00

Locality, unitarity and analyticity are some of the most fundamental properties of quantum field theory. I will show how requiring a local, analytic, unitary UV completion for a low energy effective theory (EFT) can impose positivity bounds on the Wilson coefficients of the EFT. These positivity bounds take the form of constraints on combinations of the pole subtracted scattering amplitude and...

25. Holographic entanglement entropy and its bit-thread interpretation

33. xi and ˆpi as with Noncommutative Coordinates of the Quantum Physical/Phase Space

江 祖永 (台灣中央大學)

01/07/2019, 16:00

The proper model of our physical space behind quantum mechanics is the (projective) Hilbert space which is also the phase space. The key difference between quantum mechanics and classical mechanics is just the different phase space, an infinite dimensional curved space instead of a six dimensional flat space. The latter is amazing the classical approximation of the former. We obtained all...

34. Ultrahigh Energy Cosmic Rays

马 伯强 (Peking University)

01/07/2019, 16:30

I report the assoication of ultrahigh energy cosmic neutrinos with gamma ray bursts, and from which on what we can obtain for the Lorentz invariance violation and CPT violation.

35. Quantum Correlation, Coherence & Uncertainty

费 少明 (首都师范大学)

01/07/2019, 17:00

Quantum correlations, quantum coherence and quantum uncertainty relations play significant roles in quantum information processing such as quantum communication and computation. The operational characterization of quantum correlations and quantum coherence are also the important aspects of the corresponding resource theory. We introduce some recent results on the theory of quantum...

22. The dynamics of falling charge in gravitational field

王 海军 (吉林大学)

The topic of a falling charge in gravitational field had surged quite a few times for the past decades. The equivalence principle was found to bring out different result from uniformly accelerated charge while concerning the radiation of the charge. The puzzle is still alive up to date. The problem lies in the heart of linking the electromagnetism with gravity, thus of unifying them. And...
