STM investigation of laser driven processes at surfaces 2022-01-26
Ultrashort laser pulses are an intriguing tool for driving non-adiabatic processes at surfaces. Amongst others, they may be utilized for tailoring adsorbed molecules or the surfaces themselves with…
Frequency comb interferometry 2022-01-26
A frequency comb is a broad spectrum of evenly spaced phase-coherent narrow laser lines. Initially invented for frequency metrology, such combs (often generated with ultrashort-pulse mode-locked…
Spectro-microscopy at extreme limits 2022-01-26
This talk is devoted to modern methods for attosecond and femtosecond laser spectroscopy, with a special focus on applications that require extreme spatial resolution. In the first part, I discuss…
Ultrafast terahertz physics: from single-cycle nonlinear optics to materials science on elementary timescales 2022-01-27
In this presentation the current and future research directions of AG Turchinovich will be discussed. We will start with outlining several representative results from the recent past, which…
Aqueous Systems 2022-02-10
Water is the most important liquid for life. It is intimately linked to our well-being. Without water, cell membranes cannot function. Charges and charged groups cannot be dissolved, self-assembly…
Tri-comb spectroscopy 2022-04-06
Optical multidimensional coherent spectroscopy (MDCS) has been developed over the last 20 years and proven very powerful at unfolding congested spectra, identifying coupling between resonances,…
Tunnel Magnetoresistance Detection of Skyrmion 2022-03-22
Tunnel Magnetoresistance (TMR) has been investigated to detect the passage of a skyrmion through a channel, using the properties of Magnetic Tunnel Junction (MTJ). Throughout the research, we used…
Correlated Dynamics of Driven Magnetic Skyrmions 2022-04-11
Magnetic skyrmions are topological spin configurations that can be set into motion by electric currents, magnetic fields, and laser irradiation. Achieving control over interacting ensembles of driven…
Ultrafast Fiber Lasers in 1 μm – 2 μm Wavelength Region 2022-04-08
Ultrafast fiber lasers have been received many attentions in many applications such as spectroscopy, free-space optical communications and laser surgery. Generally, the techniques for optical pulse…
