Tania Monteiro moved to UCL in 1995. She held an EPSRC Advanced Fellowship until 1999, was promoted to Reader in 1999 and then to to Professor in 2005. She is interested primarily in quantum theory, including applications to future quantum-based technologies. During her time at UCL, she has published widely in different areas of Quantum dynamics and Nonlinear dynamics. She is a Fellow of the Institute of Physics and member of the EPSRC Peer Review College. For the last three years, she has been Chair of the EPSRC-funded Collaborative Computational Project 2 (CCP2). Over the last ten years, she has taught the 2nd year, 3rd year and 4th year Quantum theory courses and in Quantum Strand Leader. She is currently Director of Graduate Studies for the Department of Physics and Astronomy.LINKS
In the early years (1995-1998) her group helped develop the theory which describes atoms in strong magnetic fields, where the motion is chaotic; and the theory for chaotic resonant tunnelling diodes. In 2001 the theory was extended to molecules in strong magnetic fields. A mechanism for the first quantum chaotic Hamiltonian ratchet using cold atoms in pulsed standing waves of light was proposed in 2002-3; this mechanism was realised experimentally in 2007 in a collaboration with the UCL cold atoms group. In 2004, a variant of the famous quantum chaos paradigm (the Quantum Kicked Rotor) was experimentally investigated at UCL using cold atoms. The new system was called "The Double-Kicked rotor". The theory developed in 2004-2007 revealed unusual quantum localization properties including a fractional dependence on Planck's constant. From 2006, investigations by her group of AC-driven or periodically pulsed BECs suggested new ways to control phase transitions such as the Mott-Insulator to Superfluid transitions, as well as new forms of directed ratchet-like transport of the cold atoms and quantum spin chains. Her group now has close links with the Quantum Information group. We also have a collaboration with the London Centre for Nanotechnology and are investigating bismuth spin qubits in silicon.
