String theory is having another bad week on the internet with feuds roiling on the social media platform X. François Chollet ...

String field theory is a second-quantised framework that recasts the perturbative dynamics of strings in terms of field-theoretic variables on the space of string configurations. By organising ...

In quantum field theory, spontaneous particle formation can occur when the potential energy between two elementary particles increases with their separation, as if they were confined by a string. When ...

Ashoke Sen, an acclaimed theoretical physicist hailing from Kolkata, received the prestigious Oskar Klein Medal in 2026. His ...

A research team led by faculty at the Duke Quantum Center (DQC) has observed string-breaking dynamics related to particle-antiparticle formation on a quantum simulator, among the first such ...

Around the end of the last century, there was a first boom in superstring theory, and it was hyped in the public eye as the ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my ...

An international team led by Innsbruck quantum physicist Peter Zoller, together with the US company QuEra Computing, has directly observed a gauge field theory similar to models from particle physics ...

Ashoke Sen’s research uses string theory to investigate black-hole entropy and the microscopic states behind it. Here is the ...

Modern string theory postulates that the elementary constituents of matter are tiny one-dimensional, string-like objects ...
