Atomistic view of the phase equilibrium and material properties of biomolecular condensates Abstract: Biomolecular condensates, formed through liquid-liquid phase separation, mediate crucial cellular functions and are linked with neurodegeneration and cancer. To reach a fundamental understanding of their phase equilibrium and material properties, we have integrated experimental techniques including optical tweezers and fluorescence imaging with […]

Early Galaxies from Rare Inflationary Processes Rare Poisson processes during cosmic inflation can generically lead to rare, high-redshift (z) galaxies. Focusing on inflationary heavy particle production as one example of a Poisson process, I will derive the redshift distribution, masses, and number densities of such early galaxies. The James Webb Space Telescope (JWST) is a powerful probe […]

Kramers Nodal Lines, Weyl Fermions and Large Anomalous Hall Effect in SmAlSi and InxTaS2 Kramers nodal lines (KNLs) are a special type of Weyl line degeneracies that connect time reversal invariant momenta (TRIM). KNLs are robust to spin orbit coupling (SOC), and are inherent to all non-centrosymmetric achiral crystal structures. In this talk, I will […]

TITLE: New perspectives on the cold neutral interstellar medium: from the Milky Way to nearby galaxies, ABSTRACT: The neutral interstellar medium (ISM) is a vital player in the star formation process, based on its major contribution to the ISM's mass, and bears the brunt of the stellar feedback. In particular, the diffuse ISM is not […]

Title: Local Probes of Spin Excitations in Quantum Matter, Abstract: Major scientific discoveries are often enabled by new measurement capabilities that provide novel perspectives into complex physical problems. Recent advances and discoveries made on quantum materials have challenged experimentalists to come up with new ways to probe their intrinsic properties. In this talk I will […]

TITLE: Viable qubits in noisy and strongly interacting systems, ABSTRACT: Quantum sensors and qubits are usually two-level systems, quantum analogs of classical bits assuming binary values ‘0' or ‘1'. They are useful to the extent to which superpositions of ‘0’ and ‘1’ persist despite a noisy environment. The standard prescription to avoid decoherence of solid-state […]

Theoretical approaches to cosmic tensions, Abstract: The Hubble and weak-lensing S8 tensions in cosmology perhaps hint at new physics beyond LCDM. I have extensively investigated these anomalies, proposing the  early dark energy (EDE) solution to the Hubble tension. Although EDE has had some successes, there are challenges yet - improving EDE's underlying fundamental model, constraining […]

Order from disorder: Designing sequence-programmable protein condensates,   Abstract: Biology provides numerous examples of phase-separated protein and nucleic acid condensates, which establish distinct compartments for spatially organizing biomolecules within living cells. This mechanism of spatial organization relies on the ability of biomolecular systems to navigate high-dimensional phase diagrams by tuning the interactions among proteins and […]
