Interpolating conformal algebra in dimensions between the instant form and the light-front form of relativistic dynamics
Hariprashad Ravikumar, Chueng-Ryong Ji
We extend the interpolation of the Poincaré algebra between instant form dynamics (IFD) and light-front dynamics (LFD) to the conformal algebra in dimensions. Building upon…
Quantum corrections as a Bound for Detecting Self-Interacting Ultralight Dark Matter
Jae-Weon Lee, Chueng-Ryong Ji
We investigate the implications of interactions between ultralight dark matter (ULDM) and Standard Model fermions for the radiative stability of the ULDM potential. By matching the…
Quantum orientation entanglement analysis of the interpolating helicity states between the instant form dynamics and the light-front dynamics
Deepasika Dayananda, Chueng-Ryong Ji
The interplay between quantum orientation entanglement and Wigner rotation plays a fundamental role in understanding the behavior of spin angular momentum in quantum states. To ana…
Interpolating conformal algebra in dimensions between the instant form and the light-front form of relativistic dynamics
Chueng-Ryong Ji, Hariprashad Ravikumar
We present the interpolating conformal algebra between the instant form dynamics (IFD) and the light-front dynamics (LFD) in dimensions, along with a interpolati…
Axial Anomaly and Confinement in Two-dimensional QED: Singular Behavior of Vacuum Polarization at Threshold
Bailing Ma, Chueng-Ryong Ji
Performing the perturbative calculation of the vacuum polarization amplitude in QED1+1, one finds an anomalous axial vector Ward identity. We note that the photon self-energy funct…
Quantum Scales of Galaxies from Self-interacting Ultralight Dark Matter
Jae-Weon Lee, Chueng-Ryong Ji
We derive the characteristic scales for physical quantities of dwarf galaxies, such as mass, size, acceleration, and angular momentum, within the self-interacting ultralight dark m…
