Nonreciprocal charge transport in topological superconductor candidate Bi2Te3/PdTe2 heterostructure

open access: yesnpj Quantum Materials, 2022
In a hybrid system of topological insulator (TI)/superconductor (SC), the proximity-induced topological superconductivity is expected to appear at the interface. Here we propose and demonstrate that a TI/SC hybrid Bi2Te3/PdTe2 heterostructure serves as a

Intrinsic coupling between spatially-separated surface Fermi-arcs in Weyl orbit quantum Hall states

open access: yesNature Communications, 2021
The spatial distribution of the quantized transport due to the presence of Weyl orbits in topological semimetals remains elusive. Here, the authors report concomitant modulation of doubly-degenerate quantum Hall states, evidencing intrinsic coupling ...

Phase transition from hadronic matter to quark matter [PDF]

open access: yes, 2006
We study the phase transition from nuclear matter to quark matter within the SU(3) quark mean field model and NJL model. The SU(3) quark mean field model is used to give the equation of state for nuclear matter, while the equation of state for color ...

Neutrino Propagation In Color Superconducting Quark Matter [PDF]

open access: yes, 2000
We calculate the neutrino mean free path in color superconducting quark matter, and employ it to study the cooling of matter via neutrino diffusion in the superconducting phase as compared to a free quark phase.
