A Route to Pure Optical Rotation in Self-Assembled Materials through Energetic Non-Degeneracy

Posted by klaurent March 16, 2026March 30, 2026Cornell

Kavli Affiliate: Richard D. Robinson | Summary:Achieving large optical rotation with minimal ellipticity and absorption, ‘pure’ optical rotation, remains a central challenge in chiral photonics. Solution-processed self-assembled materials can exhibit exceptional chiroptical responses (g-factors > 1), yet their circular birefringence (CB) typically overlaps with circular dichroism (CD) and resonant loss (Absorption), leading to elliptical, attenuated […]

Anomalous Thermal Transport Reveals Weak First-Order Melting of Charge Density Waves in 2H-TaSe2

Posted by klaurent March 16, 2026Cornell

Kavli Affiliate: David Muller | Summary:How ordered phases melt in low-dimensional quantum materials remain difficult to resolve because the relevant fluctuations are dynamic and charge neutral. In this work, we show that thermal transport provides a sensitive probe of these hidden fluctuations in the layered transition metal dichalcogenide 2H-TaSe2. We observe a striking V-shaped temperature […]

Out of oxygen: Extremely metal-poor galaxy candidates identified at $2.5 < z < 6.5$ with deep JADES medium-band imaging

Posted by klaurent March 16, 2026March 30, 2026Cambridge

Kavli Affiliate: Roberto Maiolino | Summary:JWST is beginning to uncover a population of extremely metal-poor galaxies (EMPGs, $Z < 1%~mathrmZ_odot$) at $z > 3$, mostly through serendipitous NIRSpec discoveries and blind slitless spectroscopy. To accelerate our understanding of pristine star formation, we further develop a methodology to identify EMPG candidates from photometry, using the extensive […]

BASS. LI. Cool gas supply of HI-massive local Seyfert galaxies

Posted by klaurent March 16, 2026March 30, 2026Peking

Kavli Affiliate: Claudio Ricci | Summary:We present neutral atomic hydrogen (HI) imaging observations of 22 HI-rich ($M_rm HI gtrsim 10^9.7 M_odot$), hard X-ray-selected local Seyferts to explore how cool gas is supplied to active galactic nuclei (AGN) hosts. The sample predominantly resides in group-like, gas-rich environments. About 80% (18/22) of the galaxies have HI-detected neighbors, […]

Halo assembly bias in the early Universe: a clustering probe of the origin of the Little Red Dots

Posted by klaurent March 16, 2026March 30, 2026Peking

Kavli Affiliate: Luis Ho | Summary:The clustering of galaxies encodes key information about the structure and assembly history of their host dark matter (DM) haloes, providing a powerful probe of the origin of extreme high-redshift systems. While halo assembly bias has been extensively studied at low redshift, its behavior in the early Universe remains poorly […]

Separating partially coherent light

Posted by klaurent March 16, 2026March 30, 2026Chicago

Kavli Affiliate: David W. Miller | Summary:Recent advances in optical imaging and communication increasingly involve high-dimensional, partially coherent light, creating a growing need for scalable tools to measure and manipulate coherence. Here, we demonstrate the automatic separation of spatially partially coherent light into "coherence modes" — its orthogonal and mutually incoherent components. To make this […]

Observation of two-component exciton condensates in an excitonic insulator

Posted by klaurent March 16, 2026March 30, 2026Berkeley

Kavli Affiliate: Michael Crommie | Summary:Macroscopic quantum coherence emerges when bosons condense into a Bose-Einstein condensate (BEC). First observed as a single-component superfluid in helium, BECs later emerged in ultracold atomic gases at nanokelvin temperatures as weakly interacting quantum fluids, which can also host multicomponent spinor condensates with rich internal degrees of freedom. Excitons provide […]

Multi-Plane Spatially Resolved Phase Structuring Using Optical Communication Modes

Posted by klaurent March 16, 2026March 30, 2026Chicago

Kavli Affiliate: David W. Miller | Summary:We present a deterministic framework for three-dimensional beam shaping that enables versatile control of intensity and phase, pixel-by-pixel, across multiple axial planes. Conventional multi-plane holographic techniques typically rely on iterative optimization and mitigate inter-plane crosstalk through phase randomization, introducing speckle noise and thereby limiting deterministic phase control. Here, target […]
