Bosons and Fermions System
XAT 2014 · Verbal Ability & Logical Reasoning · Hard · Paragraph Completion
In many cases in physics, one has to deal simultaneously with collective and single-particle excitations of the system. The collective excitations are usually bosonic in nature while the single-particle excitations are often fermionic. One is therefore led to consider a system which includes bosons and fermions. Hence, _____________ Which of the following options is most likely to follow the paragraph given above?
- A.
in this book, we discuss application of bosonic particles and their consequences on physics.
- B.
in this book, we discuss application of general algebraic theory of mixed Bose- Fermi systems to atomic nuclei.
- C.
in this book, we discuss excitations of collective and single particles separately.
- D.
in this book, we prove how collective excitations are bosonic and singular excitation are fermionic.
- E.
in this book, we prove that collective and singular excitation cannot exist together.
B
Explanation
The blank is preceded by the idea of systems which include both bosons and fermions. Therefore, the following sentence must talk about mixed Bose-Fermi systems.
