New Probes of Initial State of Quantum Fluctuations During Inflation
Eiichiro Komatsu - Max-Planck-Institut für Astrophysik (MPA), Garching
How did inflation actually happen? Precision measurements of statistical properties of primordial fluctuations generated during inflation offer a direct probe of the physics of inflation. When we calculate statistical properties of primordial fluctuations generated during inflation, we usually…
Correlated Electronic States in Conjugated Polymers: A DMRG Approach
S. Ramasesha - Indian Institute of Science, Bangalore
Electrons in conjugated organic polymers and molecules are strongly correlated since most of these systems are quasi one-dimensional. Experimental evidences include existence of two photons below one photon state, observation of negative spin densities in polyene radicals and qualitatively different…
The entropy power inequality for quantum systems
Robert Koenig - IBM (United States)
When two independent analog signals, $X$ and $Y$ are added together giving $Z=X+Y$, the entropy of $Z$, $H(Z)$, is not a simple function of the entropies $H(X)$ and $H(Y)$, but rather depends on the details of $X$ and $Y$'s distributions. Nevertheless, the entropy power inequality (EPI), which…
Affine Quantum Gravity: Review and Recent Results
John Klauder - University of Florida
Recent progress in the quantization of nonrenormalizable scalar fields has found that a suitable non-classical modification of the ground state wave function leads to a result that eliminates term-by-term divergences that arise in a conventional perturbation analysis. After a brief review of both…
Dark Energy and Neutrino Oscillations
Stephon Alexander - Brown University
In this talk I provide a model where the late time acceleration of the universe emerges from a BCS-like condensation of sterile neutrinos. This scenario can be naturally accommodated by general relativity covariantly coupled to sterile neutrinos, where the neutrinos act like an "aether" field. We…
Hidden Structures in High Dimensional Entanglement
Filippo Miatto - University of Strathclyde
The minimal dimension of the Hilbert space that hosts states of an entangled pair of photons can be extremely high. The process of spontaneous parametric down-conversion (SPDC) is a possible way of producing highly entangled photon pairs, in both the spatial and temporal parts of the wave function…
Gravity and Yang-Mills Sectors from a Unified Theory and Their Relation with Dark Energy
Antonino Marciano - Fudan University
We propose a new method of unifying gravity and the Yang-Mills fields by introducing a spin-foam model. We realize a unification between an SU(2) Yang-Mills interaction and 3D general relativity by considering a constrained Spin(4) ~SO(4) Plebanski action. The theory is quantized a la spin-foam by…
The DBI Pseudo-Conformal Universe: Scale Invariance from Spontaneous Breaking of Conformal Symmetry
Godfrey Miller - University of Pennsylvania
The pseudo-conformal scenario is an alternative to inflation in which the early universe is approximately described by a conformal field theory in Minkowski space. Crucially, the cosmological background spontaneously breaks the flat space so(4,2) conformal algebra down to its so(4,1) de Sitter…
On a partially Reduced Phase Space Quantisation of General Relativity Conformally Coupled to a Scalar Field
Alexander Stottmeister - University of Erlangen-Nuremberg
We comment on a certain partially reduced phase space quantisation of general relativity conformally coupled to a scalar field, and its extension to standard model matter fields. The partially reduced phase space is reached by trading the Hamiltonian constraint for the generator of local conformal…
Time and a Physical Hamiltonian for Quantum Gravity
Viqar Husain - University of New Brunswick
I will describe an approach to the problem of time that uses dust as a time variable. The canonical theory is such that there is a true Hamiltonian with spatial diffeomorphisms as the only gauge symmetry. This feature, and the form of the Hamiltonian, suggest a model for non-perturbative quantum…
