Maximizing Nonclassicality of Massive Objects via Quantum Zeno Effect
Debarshi Das, Pritam Roy, Marko Toroš +3
For testing quantum mechanics in the macroscopic domain, a major challenge is to devise effective means for enhancing the observable nonclassical signatures despite the ubiquitous…
Extended symmetry of the Maxwell theory with a gauge coupling constant as a conserved charge
Sojeong Cheong, Myungseok Eune, Wontae Kim +1
It has been proposed that any coupling constant in a covariant action can be treated as a conserved charge by promoting the coupling constant to auxiliary fields, typically realize…
Strong gravitational lensing effects of black holes with quantum hair
Sojeong Cheong, Wontae Kim
According to the no-hair theorem, stationary black holes are uniquely characterized by their mass, charge, and angular momentum. In this paper, we explore quantum hair by deriving…
Einstein ring of dust shells with quantum hair
Sojeong Cheong, Wontae Kim, Mungon Nam
The information about the internal structure of a compact object is classically inaccessible to external observers. In this paper, we investigate how quantum corrections to gravita…
Quantum geodesics reflecting the internal structure of stars composed of shells
Sojeong Cheong, Wontae Kim
In general relativity, an external observer cannot distinguish distinct internal structures between two spherically symmetric stars that have the same total mass . However, when…
