First-principle approach to the superpositions of gravitational fields in atom interferometry
Understanding the fundamental nature of gravity at the interface with quantum theory is a major open question in theoretical physics. Recent progress in experiments has enabled probing the interaction of...

New ALP probes from light meson decays
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons and pions benefit from their small total...

Causality and Ideal Measurements of Smeared Fields in Quantum Field Theory
The usual quantum mechanical description of measurements, unitary kicks, and other local operations has the potential to produce pathological causality violations in the relativistic setting of quantum field theory (QFT)...

Toys can't play: physical agents in Spekkens' theory
Information is physical, and for a physical theory to be universal, it should model observers as physical systems, with concrete memories where they store the information acquired through experiments and...

Phenomenological thermodynamics with multiple quantities of interest
Joint work (in progress) with Ladina Hausmann, Nuriya Nurgalieva and Renato Renner We can classify contemporary approaches to thermodynamics in roughly four camps: (1) Top-down microscopic approaches. These are for...

Cosmological Signatures of Interacting Dark Sectors
Models of dark sectors with a mass threshold can have important cosmological signatures. If, in the era prior to recombination, a relativistic species becomes non-relativistic and is then depopulated in...

BBN circa 2022: New Physics hints from the Early Universe?
Bang Nucleosynthesis (BBN) is one of the greatest outcome of the Standard Model of Particle Physics when put next to ΛCDM cosmology. In this talk, I will first review the...

Direct Deflection of Particle Dark Matter
Detecting light dark matter that interacts weakly with electromagnetism has recently become one of the benchmark goals of near-term and futuristic direct detection experiments. In this talk, I will discuss...

milliQan - a new experiment for heavy milli-charged particles at the LHC
milliQan is a proposed search for milli-charged particles produced at the LHC with expected sensitivity to charges of between 0.1e and 0.001e for masses in 0.1 - 100 GeV range...
