Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Tomojit Chowdhury, Aurélie Champagne, Patrick Knüppel, Zehra Naqvi, Mengyu Gao | Summary: Bilayer crystals, formed by stacking monolayers of two-dimensional (2D) crystals, create interlayer potentials that govern excitonic phenomena but are constrained by their fixed covalent lattices. Replacing one layer with an atomically thin molecular crystal […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Tomojit Chowdhury, Aurélie Champagne, Fauzia Mujid, Patrick Knüppel, Zehra Naqvi | Summary: Bilayer crystals, built from monolayers of two-dimensional (2D) crystals with different lattice orientations, generate interlayer potentials leading to unique excitonic properties. However, the ability to tune the interlayer potential is limited by the fixed […]
Kavli Affiliate: Ruobing Dong | Summary:Observations of protoplanetary disks have revealed the presence of both crescent-shaped and ring-like structures in dust continuum emission. These crescents are thought to arise from dust-trapping vortices generated by the Rossby Wave Instability (RWI), which induces density waves akin to those caused by planets. These vortices have the potential to […]

Kavli Affiliate: Yevgeny Stadnik | Summary:We propose a novel detection method for axion dark matter using the Rabi oscillation of neutron spins in beam-based measurements. If axions couple to neutron spins, a background oscillating axion dark matter field would drive transitions between spin-up and spin-down neutron states in a magnetic field when the axion particle […]

Kavli Affiliate: Jia Liu | First 5 Authors: , , , , | Summary: We investigate a fifth force mediated by a light vector boson that couples to lepton spins, characterized by axial-vector couplings to leptons and vector couplings to nucleons. This interaction generates a potential proportional to the inner product of the lepton spin […]
Kavli Affiliate: Debanjan Chowdhury | Summary:Periodically driven Floquet quantum many-body systems have revealed new insights into the rich interplay of thermalization, and growth of entanglement. The phenomenology of dynamical freezing, whereby a translationally invariant many-body system exhibits emergent conservation laws and a slow growth of entanglement entropy at certain fixed ratios of a drive amplitude […]
Kavli Affiliate: Marcela Carena | Summary:Motivated by the out-of-equilibrium dynamics during an early-universe first-order phase transition, we perform real-time simulations of fermion-bubble scattering in $1+1$ dimensions. This nonequilibrium process can generate a charge-conjugation $mathsfC$ asymmetry outside the bubble wall, induced by the complex fermion mass profile. The resulting $mathsfC$ asymmetry is the 1+1-dimensional analog of […]
