چکیده
A bstract In this paper, we study a class of symmetry reduced models $$ \mathcal{N} N = 1 super- gravity using self-dual variables. It is based on particular Ansatz for the gravitino field as proposed by D’Eath et al. We show that essential part constraint algebra in classical theory closes. particular, (graded) Poisson bracket between left and right supersymmetry reproduces Hamiltonian constraint. For quantum theory, apply techniques from manifestly supersymmetric approach to loop supergravity, which yields graded analog holonomy-flux natural state space. implement remaining constraints theory. certain subclass these models, explicitly commutator exactly relations. trace Hamilton operator. Finally, consider dynamics compare it quantization standard variables minisuperspace techniques.

p-ADIC AND ADELIC MINISUPERSPACE QUANTUM COSMOLOGY
We consider formulation and some elaboration of p-adic and adelic quantum cosmology. Adelic generalization of the Hartle-Hawking proposal does not work in models with matter fields. p-Adic and adelic minisuperspace quantum cosmology is well defined as an ordinary application of p-adic and adelic quantum mechanics. It is illustrated by a few of minisuperspace cosmological models in one, two and ...
متن کاملSupersymmetric Quantum Cosmology
The canonical quantization of N = 1 and N = 2 supergravity theories is reviewed in this report. A special emphasis is given to the topic of supersymmetric Bianchi class-A and FRW minisuperspaces, namely in the presence of supermatter fields. The quantization of the general theory (including supermatter) is also contemplated. The issue of quantum physical states is subsequently analysed. A discu...
متن کاملSupersymmetric homogeneous Quantum Cosmology
Canonical N = 1, D = 4 quantum supergravity is studied in a modeamplitude basis, where its supersymmetry generators are found to be represented by deformed exterior derivatives on configuration space. Cosmological models in supergravity are shown to be governed by the covariant version of the Witten model of supersymmetric quantum mechanics. Properties of the latter are investigated and the res...
متن کاملEssential Self-adjointness in One-loop Quantum Cosmology
The quantization of closed cosmologies makes it necessary to study squared Dirac operators on closed intervals and the corresponding quantum amplitudes. This paper shows that the proof of essential self-adjointness of these second-order elliptic operators is related to Weyl’s limit point criterion, and to the properties of continuous potentials which are positive near zero and are bounded on th...
متن کاملHomogeneous Loop Quantum Cosmology
Loop quantum cosmological methods are extended to homogeneous models in diagonalized form. It is shown that the diagonalization leads to a simplification of the volume operator such that its spectrum can be determined explicitly. This allows the calculation of composite operators, most importantly the Hamiltonian constraint. As an application the dynamics of the Bianchi I model is studied and i...
