Description
Quantum-limited devices allow to overcome classical physics limits on measurement precision. Such quantum sensors are maturing from being proof-of-principle experiments to measurement real-world measurement devices. Their use allows to improve probes of BSM physics beyond the capabilities of classical sensors. Atomic systems and NV-centers allow to probe electric and mag-netic fields, enhancing the measurement sensitivities through record-long coherence times of the individual sensors and entanglement among sensor ensembles. These systems can for instance be used to probe the very weak coupling of dark matter candidates like axions or milli-charged dark matter.
The exploration of dark matter beyond the standard lore is of vital importance towards resolving the identity of dark matter. I will discuss new proposals for the direct detection of light dark matter which hold much promise. These include the use of superconducting nanowires, two-dimensional targets such as graphene, and heavy fermion materials. Considering dark matter interactions with these...
Antiprotonic atoms have been produced since the 1980's, but recent developments of laser-controlled controlled charge exchange processes in Penning traps have opened up a wide range of new physics topics. This talk will address several of these, whose physics reach ranges from atomic cascades within antiprotonic Rydberg atoms, a new production method of trapped, cold, fully stripped...
The QUest for Axion (QUAX) is a direct-detection CDM axion search which reaches the sensitivity necessary for the detection of galactic QCD-axion in the range of frequency 8.5-11 GHz.
The QUAX collaboration is operating two haloscopes, located at Padova/LNL- and LNF-INFN laboratories in Italy, that work in synergy and operate in different mass ranges.
In this talk we will report about...
The search for a quantum theory of gravity has led to the discovery of quantum many-body systems that are dual to gravitational models with quantum properties. The perhaps most famous of these systems is the Sachdev--Ye--Kitaev (SYK) model. It features maximal scrambling of quantum information, and opens a potential inroad to experimentally investigating aspects of quantum gravity. A scalable...
