About QUINST

Quantum mechanics is at the heart of our technology and economy - the laser and the transistor are quantum devices - but its full potential is far from being realized. Recent technological advances in optics, nanoscience and engineering allow experimentalists to create artificial structures or put microscopic and mesoscopic systems under new manipulable conditions in which quantum phenomena play a fundamental role.

Quantum technologies exploit these effects with practical purposes. The objective of Quantum Science is to discover, study, and control quantum efects at a fundamental level. These are two sides of a virtuous circle: new technologies lead to the discovery and study of new phenomena that will lead to new technologies.

Our group's aim is  to control and understand quantum phenomena in a multidisciplinary intersection of  Quantum Information, Quantum optics and cold atoms, Quantum Control, Spintronics, Quantum metrology, Atom interferometry, Superconducting qubits and Circuit QED and Foundations of Quantum Mechanics.

Title: "Generalized Landauer formula for time-dependent potentials and zero bias dc current"  

 

Abstract:

Using recently developed single-electron approach for electron transport in mesoscopic (molecular) systems we derived the Landauer-type formula for time-dependent potentials, which can be applied for periodic and randomly fluctuating potentials. Using this formula we investigated conditions for appearance of dc current under zero bias voltage. We demonstrate that the effect of quantum coherence plays a crucial role in this phenomenon.
