Abstract:

Electronic transport in quasi-one dimensional (1-D) systems is mainly studied in quantum point contact (QPC) and quantum wire devices. It was first reported in QPCs of high electron mobility devices of GaAs/GaAlAs heterostructure, where steps of differential conductance (G normalized to a quantum value G0 = 2e2/h) was observed as the gate voltage was varied. Since 1988 a number of other 1-D systems from Si metal-oxide field effect transistors, GaAs type other hetero-structures and constricted graphenes etc., exhibited the quantized steps. Apart from quantized steps of universal nature (having its occurrence at integral values n=1, 2, 3, etc., for G/G0 = n) there seems to be anomalies observed in many of the above systems at the nonintegral values. Generally there are two types of anomalies: (i) Thomas and coworkers are first to identify an anomalous structure in the conductance below the first quantized step in GaAs QPCs at about 0.7 (2e2/h). It has been argued that this (0.7 anomaly) is an intrinsic property caused by many-body effect, which appears to arise independent of the materials system. Although 0.7 anomaly has been discussed abundantly in the literature, a careful observation of conductance features in all the 1D conductors would reveal anomalies at various conductance values apart from at 0.7. They occur clearly at some elevated temperature and at nonzero magnetic fields. (ii) Another anomaly has been identified in the nonlinear transport regime at low temperatures as zero-bias peak in the differential conductance while sweeping the drain bias. It is called “zero-bias anomaly” (ZBA). Explanation of these anomalies is mainly by two ideas: (1) an assumption of spontaneous spin polarization (SSP) and (2) presence of a many-body state arising out of Kondo physics. In this talk we shall critically discuss experimental findings and present various theoretical methods to explain the observed anomalies.

Menas C Kafatos

Chapman University, USA

Keynote: Universal quantum laws, health and well-being

Time : 09:45-10:45

Biography:

Menas C Kafatos is the Fletcher Jones Endowed Professor of Computational Physics, at Chapman University. He is a Quantum Physicist, Cosmologist, and Climate Change Researcher and works extensively on consciousness. He holds seminars and workshops for individuals and corporations on the natural laws that apply everywhere and are the foundations of the universe, for well-being and success. His Doctoral thesis advisor was the renowned MIT Professor Philip Morrison who studied under J Robert Oppenheimer. He has authored 315+ articles, is author or editor of 17 books, including “The Conscious Universe” (Springer), “Looking In, Seeing Out” (Theosophical Publishing House), and is co-author with Deepak Chopra of the NYT bestseller book, “You Are the Universe” (Harmony). He maintains a Huffington Post blog.

Abstract:

Quantum mechanics has opened new horizons for science, technology and all human endeavors. Both science and spiritual traditions seek unity, one by exploring the outer world, the other by exploring the inner world. The existence of un versal Laws which emerge from deep understanding of quantum mechanics, implies that we can approach science, health, wellbeing and medicine in a common philosophical framework. We explore what we have learned from quantum mechanics, phenomena such as entanglement, non-locality, the participatory nature of the universe, how they may apply to health, wellbeing and specifically to oriental medicine. The universal principles of Integrated Polarity, Recursion and Flow apply to all levels of existence and all human activities. There is a distinct possibility that what we have learned from quantum mechanics will provide clues to better understanding of the operational principles of oriental medicine, health and well-being. Common to all frameworks is the assertion that conscious Awareness is the foundation of the universe and the inner core of all human beings. Applications of quantum mechanics will extend beyond science and engineering to human beings themselves.

Abstract:

The direct simulation of life via computers is impossible. We need to do it on the quantum level, where the complexity grows exponentially. Feynman's idea is to let us build a quantum computer as a device consisting of simple quantum gates like the ordinary computer consists of transistors. And this is suitable to this theory. Experiments have shown that the decoherence is the fundamental factor, which cannot be overcome as we suppress errors in classical computations. Two facts are: the existence of the fast quantum algorithms and decoherence as the stumbling block show that we still don't quite understand how to apply quantum mechanics to complex systems. This area requires the detailed computer simulation and further experiments aimed not to single-particle but to complex phenomena in collectives of distinguishable particles. Lower bounds of quantum complexity show that quantum computer can speedup exactly tasks, which can be speedup by parallel classical performance that confirms the deep connections between quantum and classical computational parallelism. We put forward the hypothesis about universal character of classical algorithms. Any complex evolution of quantum system can be simulated classically. It means that the fundamental source of decoherence is the lack of classical memory of an abstract simulating computer. It seems very plausible that quantum computer in its specific form works in the living matter. This ''biological quantum computer'' differs from Feynman's model but it is essentially quantum and it really works. Such interesting quantum effects as dephasing assisted transport (DAT) in green sulfur bacteria, probable quantum mechanisms of olfactory and magneto reception of birds and insects can be simulated on the existing computers by the extremely simplified "qubit" models.
