Trends in condensed matter physics: is research going faster and faster?

TL;DR

This paper analyzes research trends in condensed matter physics by examining publication patterns over time, revealing common growth-decay behaviors and proposing a model to predict future research directions.

Contribution

It introduces a simple model to describe publication trends and offers predictions for future research dynamics in condensed matter physics.

Findings

Many topics exhibit initial rapid growth followed by exponential decay.

A model successfully describes the observed publication trend patterns.

Predictions suggest ongoing shifts in research focus areas.

Abstract

In this paper we study research trends in condensed matter physics. Trends are analyzed by means of the the number of publications in the different sub-fields as function of the years. We found that many research topics have a similar behavior with an initial fast growth and a next slower exponential decay. We derived a simple model to describe this behavior and built up some predictions for future trends.
