Project acronym 4DPHOTON
Project Beyond Light Imaging: High-Rate Single-Photon Detection in Four Dimensions
Researcher (PI) Massimiliano FIORINI
Host Institution (HI) ISTITUTO NAZIONALE DI FISICA NUCLEARE
Call Details Consolidator Grant (CoG), PE2, ERC-2018-COG
Summary Goal of the 4DPHOTON project is the development and construction of a photon imaging detector with unprecedented performance. The proposed device will be capable of detecting fluxes of single-photons up to one billion photons per second, over areas of several square centimetres, and will measure - for each photon - position and time simultaneously with resolutions better than ten microns and few tens of picoseconds, respectively. These figures of merit will open many important applications allowing significant advances in particle physics, life sciences or other emerging fields where excellent timing and position resolutions are simultaneously required.
Our goal will be achieved thanks to the use of an application-specific integrated circuit in 65 nm complementary metal-oxide-semiconductor (CMOS) technology, that will deliver a timing resolution of few tens of picoseconds at the pixel level, over few hundred thousand individually-active pixel channels, allowing very high rates of photons to be detected, and the corresponding information digitized and transferred to a processing unit.
As a result of the 4DPHOTON project we will remove the constraints that many light imaging applications have due to the lack of precise single-photon information on four dimensions (4D): the three spatial coordinates and time simultaneously. In particular, we will prove the performance of this detector in the field of particle physics, performing the reconstruction of Cherenkov photon rings with a timing resolution of ten picoseconds. With its excellent granularity, timing resolution, rate capability and compactness, this detector will represent a new paradigm for the realisation of future Ring Imaging Cherenkov detectors, capable of achieving high efficiency particle identification in environments with very high particle multiplicities, exploiting time-association of the photon hits.

Project acronym COMPLEXLIGHT
Project Light and complexity
Researcher (PI) Claudio Conti
Host Institution (HI) CONSIGLIO NAZIONALE DELLE RICERCHE
Call Details Starting Grant (StG), PE2, ERC-2007-StG
Summary The project is aimed at funding a multi-disciplinary laboratory on nonlinear optics and photonics in soft-colloidal materials and on “complex lightwave systems”. A team of talented young researchers, divided among experiments, theory, parallel computation and nano-fabrication is involved. The proposed research will foster several breakthrough discoveries from soft-matter to biophysics, from nonlinear and integrated optics to the science of complexity and cryptography. The underlying vision is driven by the physics of complex systems, those displaying a large number of thermodynamically equivalent states and emergent properties. There are 4 original and high-impact activities, which explore applicative potentialities: 1) sub-wavelength light filaments in soft- and bio-matter; 2) lasers in soft-matter and bio-tissues; 3) control of soft-matter lasers by light filaments; 4) complex lightwave systems, encryption by nano-structured disordered lasers. Activity 1 will lead to ultra-thin re-addressable light beams (sub-wavelength spatial solitons) propagating in soft- and bio-matter that can be used in laser-surgery, matter manipulation and able to guide high power laser pulses; activity 2 attains novel structural diagnostic techniques in bone tissue surpassing limits of nuclear magnetic resonance imaging, and assesses the field of lasers in soft-materials; activity 3 will demonstrate the control of self-organization processes in soft-matter by light filaments probed by laser emission; activity 4 is based on specific features mutuated from spin-glass theory, and will realize a novel cryptographic technique superior to chaotic systems in terms of security. Activity 1 and 2 are propaedeutic to the others. The team is composed by the Principal Investigator (P.I.), 4 post-doctoral researchers and 3 Ph.D. students. The budget will be used for paying the P.I., two post-doctoral positions, laser sources, high performance computing facilities, and instrumentation.

Project acronym INITIUM
Project an Innovative Negative Ion TIme projection chamber for Underground dark Matter searches
Researcher (PI) Elisabetta BARACCHINI
Host Institution (HI) GRAN SASSO SCIENCE INSTITUTE
Call Details Consolidator Grant (CoG), PE2, ERC-2018-COG
Summary INITIUM: an Innovative Negative Ion TIme projection chamber for Underground dark Matter searches. INITIUM goal is to boost the advancement of gaseous Time Projection Chamber detectors in the Dark Matter (DM) searches field, one of the most compelling issues of todays fundamental physics. I believe this approach to be superior because of its active neutron/electron discrimination, directional and fiducialization capability down to low energies and versatility in terms of target material. Thanks to recent advances in Micro Pattern Gas Detectors amplification and improved readout techniques, TPCs are nowadays mature detectors to aim at developing a ton-scale experiment. INITIUM focuses on the development and operation of the first 1 m3 Negative Ion TPC with Gas Electron Multipliers amplification and optical readout with CMOS-based cameras and PMTs for directional DM searches at Laboratori Nazionali del Gran Sasso (LNGS). INITIUM will put new significant constraints in a DM WIMP-nucleon scattering parameter space still unexplored to these days, with a remarkable sensitivity down to 10-42-10-43 cm2 for Spin Independent coupling in the 1-10 GeV WIMP mass region. As a by-product, INITIUM will also precisely and simultaneously measure environmental fast and thermal neutron flux at LNGS, supplying crucial information for any present and future experiment in this location. Consequently, I will demonstrate the proof-of-principle and scalability of INITIUM approach towards the development of a ton-scale detector in the context of CYGNUS, an international collaboration (of which I am one of the Spokespersons and PIs) recently gathered together with the aim to establish a Galactic Directional Recoil Observatory, that can test the DM hypothesis beyond the Neutrino Floor and measure the coherent scatter of galactic neutrinos, generating a significant long-term impact on detection techniques for rare events searches.

Project acronym MEGANTE
Project MEasuring the Gravitational constant with Atom interferometry for Novel fundamental physics TEst
Researcher (PI) Gabriele ROSI
Host Institution (HI) ISTITUTO NAZIONALE DI FISICA NUCLEARE
Call Details Starting Grant (StG), PE2, ERC-2018-STG
Summary Starting from the original experiment performed by Henry Cavendish more than two centuries ago, the precision determination of the gravitational constant G remains a challenging endeavour. It has been measured about a dozen times over the last 50 years, but the results have varied much more than what would be expected from random and
systematic errors. Likely, this is due to the fact that, so far, all the past experiments have relied on macroscopic classical instruments, which could all be governed by uncontrolled mechanical influences. On the other hand, a recent controversial study about correlations between the measured values of G and the variations of the length of day seems to suggest that some other not well-understood effects could be present.
MEGANTE will address all these issues by carrying out precision G determinations making use of original experimental strategies based on quantum sensors. Unprecedented accuracy levels will be achieved using cold atoms in free-fall to probe the gravitational field, surpassing thus the state-of-art measurements based on torsion balance and simple pendulum.
In parallel, MEGANTE will provide results that go far beyond the pure metrological interest. Indeed, owing the lack of a full understanding of gravity, several theoretical models predict new physics phenomena such violations of the inverse square law or a dependency of the G value from the local density of the matter. These aspects of the gravitational interactions will be thoroughly examined during the project, improving current constrains on those theories.
MEGANTE will define a novel paradigm for precision G measurements and experiments on gravitation, paving the way for a final resolution of a two-centuries-old problem in metrology.

Project acronym QUPOL
Project Quantum gases of ultracold polar molecules
Researcher (PI) Giovanni Modugno
Host Institution (HI) LABORATORIO EUROPEO DI SPETTROSCOPIE NON LINEARI
Call Details Starting Grant (StG), PE2, ERC-2007-StG
Summary I propose to realize quantum gases of ultracold molecules with a permanent electric dipole moment. This project aims at a significant extension of the field of ultracold quantum gases towards more complex particles interacting via long-range, anisotropic interactions. Quantum gases of polar molecules would allow to study novel kinds of matter waves, to solve open questions in modern condensed matter physics, to explore novel quantum phases and to implement novel quantum computing schemes. Weakly bound heteronuclear dimers formed in ultracold atomic quantum mixtures via magnetic Feshbach resonances will be coherently transferred to deeply-bound ro-vibrational states using laser fields. The formation of both bosonic and fermionic molecules will be explored in different alkali mixtures. The high degree of coherence of the molecular quantum gases will allow to prepare them in selected rotational states of the absolute ground electronic and vibrational state. The molecular electric dipoles will be manipulated via electric and microwave fields. The precise dynamical control of the shape and strength of the dipole-dipole potential will allow to engineer a variety of quantum states and to study many interdisciplinary phenomena. The following themes will be explored: phenomenology of dipolar quantum gases, lattice spin models, polar molecules as qubits.
