अल्बर्ट आइंस्टीन के अनुसार "यह वह सिद्धांत है जो तय करता है कि क्या देखा जा सकता है!" सिद्धांत के बिना विज्ञान अकल्पनीय है - सिद्धांतकार प्रकृति के संचालन के बारे में हमारी मूलभूत समझ प्रदान करते हैं, और इस ज्ञान को व्यावहारिक अनुप्रयोगों में भी बदल सकते हैं।
जेएनसीएईआर के सैद्धांतिक विज्ञान एकक में, हमारा उद्देश्य उस समृद्ध विविधता की आवश्यकताओं को पूरा करना, समझाना और समझना है जो हम भौतिक दुनिया में देखते हैं। हम इस समझ का उपयोग नई घटनाओं की भविष्यवाणी करने या नई सामग्रियों को डिजाइन करने के लिए भी करते हैं। इसके लिए हम सैद्धांतिक भौतिकी और रसायन शास्त्र के साथ-साथ गणित की तकनीकों का उपयोग करते हैं। हम अंतःविषय क्षेत्रों (जैसे विकासपरक जीव विज्ञान) में भी रुचि रखते हैं जिसमें नई अंतर्दृष्टि प्राप्त करने के लिए भौतिकी से तकनीकों और विचारों का उपयोग किया जा सकता है।
The research in our Unit is inspired by two complementary approaches to the study of matter and life: the search for universality and the exploration and explanation of diversity.In the very early universe, matter was homogeneous, but this is clearly no longer so. Due to spontaneously broken symmetries and sequences of phase transtions, the world around us now exhibits variety and complexity: carbon is ultrahard as diamond but soft as graphite, ice contracts when it melts, wheareas 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 understand this perplexing yet fascinating range of behaviour, we have to examine structures and properties at a fundamental level, and consider the complex consequences of having a large number of entities (be they electrons, atoms, molecules or living creatures) that interact strongly with one another. Even when the underlying natural laws are simple in form, complex behaviour 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 basic training in many body physics, computational chemistry, quantum mechanical density functional theory, statistical mechanics and mathematical physics. However, much of the work we currently pursue is interdisciplinary in nature, so that we turn the boundaries between these fields into seamless ones. Accordingly, we also accept students who have undergraduate or graduate degrees in a variety of academic disciplines, such as chemistry, physics, engineering and computer science.
In addition to collaborating amongst ourselves on various problems, all of us also interact intensively with our experimental colleagues, both in JNCASR and outside. We also use a mixture of analytical and computational techniques; in the latter, we are helped by the presence of high-performance computational facilities at JNCASR.
The atmosphere in our Unit is vibrant, informal and interactive. Our faculty and students participate in a number of national and international conferences and workshops, we organize several seminars and colloquia ourselves, and have a constant stream of distinguished visitors. Alumni of our Unit have excelled in their careers; several of them are now establishing their own groups at universities in India and abroad. We are always on the lookout for bright students who are curious about science and dedicated to research; we urge you to contact us if you are one of them!
