Superconductivity distorts crystal lattice of topological quantum materials

Superconductors (materials that conduct electricity without resistance) have fascinated physicists for more than a century. While conventional superconductors are well understood, a new class of materials known as topological superconductors has attracted intense interest in recent years.

These superconductors have been reported to be capable of hosting Majorana quasiparticles, exotic states that could change the field of fault-tolerant quantum computing. Yet many of the fundamental properties of these novel bulk topological superconductors remain relatively unknown, leaving open questions about how their unusual electronic states interact with the underlying .

In a new study conducted by Professor Guo-qing Zheng, along with Kazuaki Matano, S. Takayanagi, K. Ito of Okayama University and Professor H. Nakao of High Energy Accelerator Research Organization (KEK), published in Physical Review Letters on August 22, 2025, the researchers report that the doped topological insulator CuxBi2Se3 undergoes tiny but spontaneous distortions in its crystal lattice as it enters the superconducting state.

Caltech Shatters Record With 6,100-Qubit Quantum Array

The neutral-atom platform appears promising for scaling up quantum computers. To solve some of the toughest challenges in physics, chemistry, and other fields, quantum computers will eventually need extremely large numbers of qubits. Unlike classical bits that can only represent a 0 or a 1, qubits

Researchers Have Discovered a Way To Simulate the Universe — on a Laptop

Cosmologists can now explore data faster than ever before with a new emulator. As astronomers continue to uncover the mysteries of the universe, their work generates increasingly vast and intricate data sets. A recent innovation is making it possible for researchers to process these enormous collec

Scientists Accidentally Create a “Rainbow Laser” on a Tiny Chip

While developing LiDAR technology, scientists unexpectedly discovered how to generate multiple laser colors from a single chip.

Their innovation could transform data centers and communications by delivering faster, cleaner, and more efficient light sources.

New haptic system lets soft objects respond to taps, squeezes and twists

New technology that invites expressive, two-way communication between a person and the soft, flexible object they are holding or wearing has been developed at the University of Bath.

Using this system, a user can tap, twist or pinch a soft object—such as a cushion, an item of clothing or a pliable computer mouse—and the object will respond in a meaningful way, for instance, by changing the TV channel, turning off a light or creating a digital sculpture on a screen.

Crucially, the object also provides (such as a soft click or vibration) to confirm the action, while maintaining its natural softness and flexibility.

Climate-smart housing design helps cities beat the heat

Painting walls in light colors, insulating roofs, choosing medium-sized windows, and aligning buildings to the sun’s path may seem like simple choices. But they could provide powerful defenses against climate change for millions of people in the world’s most vulnerable regions.

That’s the message of a study, appearing in the journal Energy and Buildings, which identifies low-cost, climate-smart design strategies as crucial for future housing in Latin America’s rapidly warming cities.

Researchers used computer simulations to test how various climate-resilient building projects would perform under current and projected climate conditions in five major cities—Rio de Janeiro and São Paulo, in Brazil, Santiago (Chile), Bogotá (Colombia), and Lima (Peru).

HALO: hierarchical causal modeling for single cell multi-omics data

Chromatin accessibility dynamics causally influence changes in gene expression levels, but these fluctuations may not be directly coupled over time. Here, authors develop computational causal framework HALO, examining epigenetic plasticity and gene regulation dynamics in single-cell multi-omic data.

Computational Creativity Research: Towards Creative Machines

Computational Creativity, Concept Invention, and General Intelligence in their own right all are flourishing research disciplines producing surprising and captivating results that continuously influence and change our view on where the limits of intelligent machines lie, each day pushing the boundaries a bit further. By 2014, all three fields also have left their marks on everyday life – machine-composed music has been performed in concert halls, automated theorem provers are accepted tools in enterprises’ R&D departments, and cognitive architectures are being integrated in pilot assistance systems for next generation airplanes.
