I am delighted to let you know that our recent work on the 'thermal quenching' of scrambling has been accepted as a letter in Physical Review E! @YairLitman @LarsMe1812. journals.aps.org/pre/abstrac…

Thermal quenching of classical and semiclassical scrambling

Quantum scrambling often gives rise to short-time exponential growth in out-of-time-ordered correlators. The scrambling rate over an isolated saddle point at finite temperature is shown here to be...

A new path-integral method for calculating exact, vibrationally resolved tunneling splittings using classical molecular dynamics. pubs.aip.org/aip/jcp/article…

Exact tunneling splittings from symmetrized path integrals

We develop a new simulation technique based on path-integral molecular dynamics for calculating ground-state tunneling splitting patterns from ratios of symmetr

Excited to present our theory @PNASNews on the existence of a bound on quantum chaos. We show this bound is controlled by 'instantons', thus connecting chaos to quantum tunnelling @ChemCambridge @stjohnscam @Cambridge_Uni @ChemColumbia @ETH #compchem pnas.org/doi/10.1073/pnas.23…
