Semiclassical multi-mode squeezed states in harmonic cosmology
Bekir Baytaş
Harmonic cosmology is an algebraic framework based on the Lie algebra that underlies the effective dynamics of loop quantum cosmology and group field theory. F…
Degenerate Limits of Scalar-Tensor Gravity
Bekir Baytaş, Xiao-Kan Guo
We study the degenerate limits of the scalar-tensor theory of gravity in its Hamiltonian connection dynamics formulation. The degenerate limit of the spatial triad is effectuated b…
Bosonic and fermionic statistics in nonperturbative quantum gravity
Bekir Baytaş, Patrick L. Rodrigues, Nelson Yokomizo
The relation between spin and statistics in quantum field theory relies on Poincaré invariance, a symmetry that is lost in the presence of a gravitational field, and replaced in ge…
A class of entangled and diffeomorphism-invariant states in loop quantum gravity: Bell-network states
Bekir Baytaş
Bell-network states constitute a class of diffeomorphism-invariant and entangled states of the geometry within loop quantum gravity (LQG) that satisfy an area-law for the entanglem…
Effective geometry of Bell-network states on a dipole graph
Bekir Baytaş, Nelson Yokomizo
Bell-network states are a class of entangled states of the geometry that satisfy an area-law for the entanglement entropy in a limit of large spins and are automorphism-invariant,…
Cosmological states in loop quantum gravity on homogeneous graphs
Bekir Baytas, Nelson Yokomizo
We introduce a class of states characterized by proposed conditions of homogeneity and isotropy in loop quantum gravity and construct concrete examples given by Bell-network states…
Minisuperspace results for causal dynamical triangulations
Bekir Baytas, Martin Bojowald, Sean Crowe +1
Detailed applications of minisuperspace methods are presented and compared with results obtained in recent years by means of causal dynamical triangulations (CDTs), mainly in the f…
Equivalence of models in loop quantum cosmology and group field theory
Bekir Baytas, Martin Bojowald, Sean Crowe
The paradigmatic models often used to highlight cosmological features of loop quantum gravity and group field theory are shown to be equivalent, in the sense that they are differen…
Effective potentials from semiclassical truncations
Bekir Baytas, Martin Bojowald, Sean Crowe
Canonical variables for the Poisson algebra of quantum moments are introduced here, expressing semiclassical quantum mechanics as a canonical dynamical system that extends the clas…
Canonical Tunneling Time in Ionization Experiments
Bekir Baytas, Martin Bojowald, Sean Crowe
Canonical semiclassical methods can be used to develop an intuitive definition of tunneling time through potential barriers. An application to atomic ionization is given here, cons…
Faithful realizations of semiclassical truncations
Bekir Baytas, Martin Bojowald, Sean Crowe
Realizations of algebras in terms of canonical or bosonic variables can often be used to simplify calculations and to exhibit underlying properties. There is a long history of usin…
