A speculation about a puzzled result in energy spectrum of cosmic-ray electrons around TeV energies
Wei Zhu, Jianhong Ruan, Peng Liu +2
Nuclear Coulomb potential at completely ionized and extremely thin atmosphere can leaks to a macroscopic spatial scale. This effect is used to explain the difference between the en…
Dark Matter Particle Explorer observations of high-energy cosmic ray electrons plus positrons and their physical implications
Qiang Yuan, Lei Feng
The DArk Matter Particle Explorer (DAMPE) is a satellite-borne, high-energy particle and -ray detector, which is dedicated to indirectly detecting particle dark matter and study…
Density waves and jet emission asymmetry in Bose Fireworks
Han Fu, Lei Feng, Brandon M. Anderson +5
A Bose condensate subject to a periodic modulation of the two-body interactions was recently observed to emit matter-wave jets resembling "fireworks" [Nature 551, 356(2017)]. In th…
Quantum Simulation of Coherent Hawking-Unruh Radiation
Jiazhong Hu, Lei Feng, Zhendong Zhang +1
Exploring quantum phenomena in a curved spacetime is an emerging interdisciplinary area relating many fields in physics such as general relativity, thermodynamics, and quantum info…
The Energy Dependence of Micro Black Hole Horizon in Quantum Gravity Theory
Lei Feng
The energy dependence of the deflection angle is a common prediction in some quantum gravity theories when the impact parameters are much larger than the photon wavelength. For low…
Search for line signal candidates in the Fermi-LAT data
Shang Li, Zi-Qing Xia, Yun-Feng Liang +7
In order to search for the line-like signals in the Fermi-LAT data, we have analyzed totally 49152 regions of interest (ROIs) that cover the whole sky. No ROI displays a line signa…
Search for gamma-ray emission from the nearby dwarf spheroidal galaxies with 9 years of Fermi-LAT data
Shang Li, Kai-Kai Duan, Yun-Feng Liang +8
In this work, we search for -ray emission from the directions of some nearby Milky Way dwarf spheroidal galaxies (dSphs) and candidates with the publicly-available Pass 8 data o…
Looking for the gluon condensation signature in proton using the Earth limb gamma-ray spectra
Lei Feng, Jianhong Ruan, Fan Wang +1
A new type of gamma ray spectrum is predicted in a general hadronic framework if considering the gluon condensation effects in proton. The result presents the power-law with a shar…
Constraints on axion-like particle properties with very high energy gamma-ray observations of Galactic sources
Yun-Feng Liang, Cun Zhang, Zi-Qing Xia +3
Axion-like particles (ALPs) can oscillate to photons and vice versa in electromagnetic fields. The photon-ALP oscillation provides an attractive solution to the apparent transparen…
Complex correlations in high harmonic generation of matter-wave jets revealed by pattern recognition
Lei Feng, Jiazhong Hu, Logan W. Clark +1
Correlations in interacting many-body systems are key to the study of quantum materials and quantum information. More often than not, the complexity of the correlations grows quick…
New Bounds on Axion-Like Particles From the Fermi Large Area Telescope observation of PKS
Cun Zhang, Yun-Feng Liang, Shang Li +5
The axion-like particle (ALP)-photon mixing in the magnetic field around -ray sources or along the line-of-sight could induce oscillation between photons and ALPs, which then ca…
Observation of density-dependent gauge fields in a Bose-Einstein condensate based on micromotion control in a shaken two-dimensional lattice
Logan W. Clark, Brandon M. Anderson, Lei Feng +3
We demonstrate a density-dependent gauge field, induced by atomic interactions, for quantum gases. The gauge field results from the synchronous coupling between the interactions an…
Searching for spectral oscillations due to photon-axionlike particle conversion using the Fermi-LAT observations of bright supernova remnants
Zi-Qing Xia, Cun Zhang, Yun-Feng Liang +4
Axionlike-particles (ALPs) are one promising type of dark matter candidate particle that may generate detectable effects on -ray spectra other than the canonical weakly interact…
