Quantum Dispersive Waves and Multimode Squeezing in Pure-Kerr Parametrically Driven Cavity Solitons
Announce Type: replace-cross Abstract: Parametrically driven cavity solitons (PDCS), unlike single-pumped cavity solitons, are localized optical pulses arising from parametric processes. These cavity solitons, recently discovered in pure-Kerr media, offer great promise for nonlinear dynamics studies and metrology.
Soliton crystal formation in Kerr cavities with an avoided mode crossing: a theoretical study
arXiv:2606.03202v1 Announce Type: new Abstract: We theoretically and numerically investigate the formation of soliton crystals in Kerr microresonators in the presence of an avoided mode crossing (AMX). Our study combines dynamical simulations based on a modified Lugiato-Lefever equation (LLE) with a stability analysis of its stationary solutions. We show that, depending on its strength and spectral position, the AMX can either stabilize otherwise unstable soliton crystals or induce Turing...
Kerr-induced In-line Interferometry for Ultra-sensitive Phase-Contrast Imaging
Announce Type: replace Abstract: Measuring the phase of light is fundamental to optical imaging, sensing, and signal processing applications. Conventional optical phase measurements rely on multipath configurations, bulky interferometric setups, and computationally intensive data pipelines, limiting scalability, robustness, and practicality. We introduce a technique that allows for reference-free in-line phase retrieval of abrupt phase transitions in optical pulses directly from spectral...
McCullum and Key are lucky to have kept their jobs. Now they have to nail England’s rebuild | Mark Ramprakash
Series against New Zealand will be a litmus test to see if the leadership team’s failed approach has really changedThere’s a quote from Legacy, James Kerr’s book about the All Blacks, that I have always liked: “Our values decide our character, our character decides our value.” As England’s Test side sets about its great post-Ashes reset, I think it is applicable. Culture is a work in progress and always will be, and the positive that has emerged from their winter in Australia – when, on and...

‘Mogging’ is suddenly everywhere. Is that a problem?
This word for outdoing or outshining others originated in the manosphere, but is now thoroughly mainstream. Why is it so popular – and should we be worried about slang that arises from toxic subcultures?Until recently, if someone had said “mog” to me, I probably would have assumed they were talking about the children’s book cat created by the late great Judith Kerr. If asked about “mogging” or being “mogged,” I would have been completely baffled.
Why has Belfast erupted in anti-immigrant violence after a knife attack?
Why has Belfast erupted in anti-immigrant violence after a knife attack? Ministers have blamed far-right online agitators for stoking racial tension following a stabbing. Anti-immigration protests have broken out in Belfast, Northern Ireland, after a knife attack allegedly perpetrated by a Sudanese refugee left the country on edge.

live Matildas vs Mexico, live updates, international friendly in Sydney The Matildas will be hoping for a degree of redemption as they look to put Saturday night's disjointed performance in Newcastle to bed in their second international against Mexico. The game is a milestone one for Caitlin Foord, who will play her 150th match for the Matildas. Follow the live blog below.
From Patrick Ewing to Jalen Brunson, the Knicks' Finals run connects two eras
NEARLY THREE DECADES later, Patrick Ewing's pain is fresh as he reminisces about the last time the New York Knicks were in the NBA Finals. In 1999, the upstart Knicks became the first 8-seed ever to reach the Finals, but they were no match for the San Antonio Spurs. Tim Duncan was just starting his legendary Spurs run of five titles in 16 seasons, and center David Robinson was still at an All-Star level.
Optical Poling Reveals Hidden Molecular Restructuring in Multimode Fibers, Unlocking Ultra-Efficient Third-Order Nonlinearities
Announce Type: new Abstract: Optical poling is a well-established technique for inducing \chi^{(2)} nonlinearity, yet its impact on silica's molecular structure remains unexplored. Here, we report the first direct observation of molecular restructuring in large-core graded-index multimode fibers (MMFs) induced by optical poling, transforming the silica tetrahedral ring network. Through coherent light beating, this process converts large rings of more than four SiO_4 tetrahedra into smaller...
