External Energy Paradigm For Black Holes
Yuan K. Ha
A new paradigm for black holes is introduced. It is known as the External Energy Paradigm. The paradigm asserts that all energies of a black hole are external quantities; they are…
Weighing the Black Hole via Quasi-local Energy
Yuan K. Ha
We set to weigh the black holes at their event horizons in various spacetimes and obtain masses which are substantially higher than their asymptotic values. In each case, the horiz…
The Horizon Energy of a Black Hole
Yuan K. Ha
We investigate the energy distribution of a black hole in various spacetimes as reckoned by a distant observer using the quasi-local energy approach. In each case the horizon mass…
Weighing The Black Holes Of GW150914
Yuan K. Ha
We evaluate the mass of the black holes of GW150914 at their event horizons via quasi-local energy approach and obtain the values of 71 and 57 solar masses, compared to their asymp…
Bosonization and Lie Group Structure
Yuan K. Ha
We introduce a concise quantum operator formula for bosonization in which the Lie group structure appears in a natural way. The connection between fermions and bosons is found to b…
Symmetries in Bosonization
Yuan K. Ha
Two-dimensional quantum field theories are important in many problems in physics because they contain exact symmetries and are often completely integrable. We demonstrate the power…
