Flagship projects, research groups

LASRAM

Investigation and application (e.g. medical) oriented optimization of infrared (1500 nm and 2000 nm) diode lasers including their fiber coupling. Laser diode: maximum stable output power, effect of thermal conditions, determination of pulse and beam parameters. Beam guiding: identification and minimization of losses (by means of beam shaping and coupling optics), investigation of optical properties and boundary surface damage.

Nanoelectronics

Materials show new conducting properties at nanometer scale. Understanding this is a big challenge for the theoretical research, but it may give new functionalities for applications. We make nanocircuits in various ways: hybrid nanosystems containing superconductors and ferromagnet, molecular contact, and memristive structures. In measurements at low temperature the quantum effects, the wave nature, or the spins of the electrons play an important role. Website of the research group: http://nanoelectronics.physics.bme.hu

Exotic Quantum Phases Group

The Exotic Quantum Phases Group is a joint high-profile research group of  the Hungarian Academy of Sciences and the Technical University. Its research focuses mostly on the quantum theory of engineered quantum systems such as ultracold atomic systems, nanoscale artificial atoms and molecules, and hybrid systems, their dyanmical and out of equilibrium properties, and the novel quantum phases appearing in these systems.

Medicontur - intraocular eyelens examination

The project topic is the scientific examination of the optical properties of implanted intraocular lens (IOL) provided for cataract patients and related production technology development. The goal is to provide patients with implanted artificial eye lens with an optical performance that reaches the healthy eye visual ability. The modelling of the lens in a realistic eye model, the development of new diagnostic procedures and measurement of the errors of the lens mapping, light scattering properties and testing of accommodative power is required.

One-dimensional quantum systems

Our group studies the dynamics of one-dimensional quantum systems, such as spin chains, one-dimensional Bose gases, and related quantum field theory models. Compared to higher dimensional systems, quantum effects and correlations between the degrees of freedom play a much more important role in one dimension, resulting in numerous exotic phenomena. In a significant part of these phenomena the so-called integrability and its breaking plays a central role.

FP7 3x3D

We propose to engineer and validate a novel random access three-dimensional two-photon (2P) laser scanning microscope which can simultaneously image three different brain regions in the three spatial dimensions (3x3D system), where each scanned volume can exceed cubic millimetres. We will validate the capability of our 3x3D system by simultaneously performing retinal, lateral geniculate nucleus, and cortical 3D imaging and photo stimulation.
