It is the idea that decides what are often observed!”, said Albert Einstein. Science without theory is unthinkable: theoreticians provide our fundamental understanding of how nature operates and may also turn this data into practical applications. In the Theoretical Sciences Unit at JNCASR, we aim to deal with, explain and understand the rich diversity we observe within the physical world. We also use this understanding to predict new
phenomena or design new materials. For this, we use the techniques ot theoretical
physics and chemistry, also as mathematics. We also are curious about interdisciplinary areas (such as
evolutionary biology) during which techniques and concepts from
physics are often wont to gain fresh insight. The research in our Unit is inspired by two complementary approaches to the study of matter and life: the look for universality and therefore the exploration and explanation of diversity. In the very early universe, matter was homogeneous, but this is often clearly not so. Due to spontaneously broken symmetries and sequences of phase transitions, the planet around us now exhibits variety and complexity: carbon is ultrahard as diamond but soft as graphite, ice contracts when it melts, whereas copper expands, chewing gum stretches when stepped on while glass shatters, most of life is multicellular and sexually reproducing though these are "expensive" traits. Why?? In order to know this perplexing yet fascinating range of behavior, we've to look at structures and properties at a fundamental level, and consider the complex consequences of getting a large number of entities (be they electrons, atoms,
molecules or living creatures) that interact strongly with each other . Even when the underlying natural laws are simple in form, complex behavior can be manifested as system sizes increase; this is known as "emergence” and is of fundamental interest to us.Our faculty members have had their military training in many body physics, computational chemistry, quantum mechanical density functional theory, physics, and mathematical physics. However, much of the work we currently pursue is interdisciplinary in nature, in order that we turn the boundaries between these fields into seamless ones. Accordingly, we also accept students who have undergraduate or graduate degrees during a sort of academic disciplines, like chemistry, physics, engineering, and computing.
