Unusual persistence of superconductivity against high magnetic fields in the strongly-correlated iron-chalcogenide film FeTe:O
I. K. Dimitrov, W. D. Si, W. Ku +2
We report an unusual persistence of superconductivity against high magnetic fields in the iron chalcogenide film FeTe:O below ~ 2.5 K. Instead of saturating like a mean-field…
Analytical and Experimental Study of X-ray Absorption Coefficients of Material by Abel's Inversion
S. J. Han
The hard x-ray gamma-ray absorption by cylindrically symmetric U-238 test objects is studied by means of gamma-ray transmission measurements. To make a precise comparison between t…
Stability of a Charged Particle Beam in a Resistive Plasma Channel
S. J. Han
A self-focusing of a coasting relativistic beam in a plasma channel that is confined by an external magnetic field is studied as a means of reconditioning the beam emerging from a…
Coherent Collective Excitations in a Superfluid: Spontaneously Broken Symmetries and Fluctuations-Dissipation
S. J. Han
This paper presents an elementary theory of the phase-coherent collective excitations in both He II in the gravitational field and atomic Bose-Einstein condensation in a trap. The…
Atomic Theory of the Two-fluid Model: Broken Gauge Symmetry in Bose-Einstein condensation
S. J. Han
We discuss the collective excitations in a spatially inhomogeneous (cylindrically symmetric) Bose-Einstein condensation (BEC) at low temperature (). The main result is t…
Quantum Hamilton-Jacobi Equation and Broken Symmetry in Hydrodynamics of Liquid Helium II
S. J. Han
Based on the quantum theory of Bohm and the phase coherence along with the mean field of Penrose and Onsager, it is shown that a free surface of He II behaves like a classical flui…
