Late-time Structure of the Bunch-Davies FRW Wavefunction
George Konstantinidis, Raghu Mahajan, Edgar Shaghoulian
In this short note we organize a perturbation theory for the Bunch-Davies wavefunction in flat, accelerating cosmologies. The calculational technique avoids the in-in formalism and…
Late-time Structure of the Bunch-Davies De Sitter Wavefunction
Dionysios Anninos, Tarek Anous, Daniel Z. Freedman +1
We examine the late time behavior of the Bunch-Davies wavefunction for interacting light fields in a de Sitter background. We use perturbative techniques developed in the framework…
Quantum coherence in momentum space of light-matter condensates
C. Antón, G. Tosi, M. D. Martín +6
We show that the use of momentum-space optical interferometry, which avoids any spatial overlap between two parts of a macroscopic quantum state, presents a unique way to study coh…
Conformal Quivers and Melting Molecules
Dionysios Anninos, Tarek Anous, Paul de Lange +1
Quiver quantum mechanics describes the low energy dynamics of a system of wrapped D-branes. It captures several aspects of single and multicentered BPS black hole geometries in fou…
Microwave and millimeterwave electrical permittivity of graphene monolayer
Alina Cismaru, Mircea Dragoman, Adrian Dinescu +3
The effective electrical permittivity of a graphene monolayer is experimentally investigated in the 5-40 GHz range, which encompasses the microwave and the lower part of millimeter…
Higher Spin de Sitter Holography from Functional Determinants
Dionysios Anninos, Frederik Denef, George Konstantinidis +1
We discuss further aspects of the higher spin dS/CFT correspondence. Using a recent result of Dunne and Kirsten, it is shown how to numerically compute the partition function of th…
Supergoop Dynamics
Dionysios Anninos, Tarek Anous, Frederik Denef +2
We initiate a systematic study of the dynamics of multi-particle systems with supersymmetric Van der Waals and electron-monopole type interactions. The static interaction allows a…
Radio frequency signal detection by ballistic transport in Y-shaped graphene nanoribbons
George Deligeorgis, Fabio Coccetti, George Konstantinidis +1
We report on the fabrication and room temperature measurements of a high frequency electrical signal detector. The device is based on the ballistic transport in graphene to detect…
Graphene-like metallic-on-silicon field effect transistor
M. Dragoman, G. Konstantinidis, K. Tsagaraki +3
In this manuscript, we present a field effect transistor with a channel consisting of a two-dimensional electron gas located at the interface between an ultrathin metallic film of…
Graphene radio: Detecting radiowaves with a single atom sheet
Mircea Dragoman, Dan Neculoiu, Alina Cismaru +3
We present the experimental evidence of RF demodulation by a graphene monolayer embedded in a coplanar structure. The demodulator was tested in the frequency range from 100 MHz to…
