This dissertation focuses on methods which aid in the study of exotic phases of matter in quantum many-body systems. For this I look specifically at systems with local disorder that can give rise to the phenomenon of many-body localization as well as two-dimensional systems with certain local symmetries, which I show can potentially lead to the emergence of topologically ordered phases. In this work I use a group-theoretical approach to investigate the topological properties of two-dimensional materials, with a specific focus on the effects of local SU(3) symmetries in the Kagome lattice and enhance this theoretical approach by a numerical analysis that utilizes tensor network constructs. To further investigate the effects of disorder on a quantum many-body system, I derive analytical solutions to time-evolved local observables in many-body localized systems with random perturbation, which I subsequently use to design a tensor network framework by which I combine variational and perturbative solutions for quantum many-body systems to efficiently calculate the time-evolved values of relevant observables.

In early 2020 we looked at the causes of COVID-19 lockdown policies in US states using a panel data analysis and created interactive slides.

This new Hubblecast episode takes a detailed look into the refined Pointing Control System that allows Hubble to keep its gaze into the Universe firm and steady.

As the final crescendo of the Telling Responsible Stories course at the Munich Center for Technology in Society, my team and I released a podcast episode on how researchers, policy makers, philosophers, and the media deal with scientific uncertainty.

Beginning a PhD is a big step for a student in academia. However, there are several difficulties that come in the first year of PhD. What they are and how to...

We construct a topological spin liquid (TSL) model on the kagome lattice,with SU(3) symmetry with the fundamental representation at each lattice site,based on Projected Entangled Pair States (PEPS). Using the PEPS framework, wecan adiabatically connect the model to a fixed point model (analogous …

The dynamics of interacting quantum systems in the presence of disorder isstudied and an exact representation for disorder-averaged quantities via Itostochastic calculus is obtained. The stochastic integral representation affordsmany advantages, including amenability to analytic approximation, ap…

Quantum spin systems have been providing modern physics with ever new challenges to tackle in the past several decades; from the theoretical postulation of topological quantum order, a new chapter was revealed in the understanding of phase transitions in quantum systems. The novel properties of topo…

At the 2020 Soapbox Science Munich event, I spoke about my area of expertise — quantum science that will (or won’t) change the world of the future.

I held a science slam talk about how public policies are created and how important it is for quantum experts to speak up and have their voices heard.

I held a talk at the Quantum Technologies Meetup hosted by IBM in Munich on 2019/04/04. Behold, the slides!

By Ivana Kurecic and Chloe Hill — What motivates scientists to engage with policymaking? As researchers, most of us entered our scientific disciplines to gain a better understanding of the world, or by our desire to contribute to society by developing new technologies and techniques. One of the questions researchers often ask themselves is exactly how their research impacts the world and by what means.

Rock-solid Certainty? When astronomers around the globe discovered an unusual object passing through our Solar System in late 2017, the race was on to work out what it was and where it came from. The first interstellar visitor we had ever spotted — ’Oumuamua — was already moving away from the Sun,…

2018 ESO Media Highlights

Deep observations made with the MUSE spectrograph on ESO’s Very Large Telescope have uncovered vast cosmic reservoirs of atomic hydrogen surrounding distant galaxies. The exquisite sensitivity of MUSE allowed for direct observations of dim clouds of hydrogen glowing with Lyman-alpha emission in the …

The faint, ephemeral glow emanating from the planetary nebula ESO 577-24 persists for only a short time — around 10,000 years, a blink of an eye in astronomical terms. ESO’s Very Large Telescope captured this shell of glowing ionised gas — the last breath of the dying star whose simmering remains ar…

ESO’s planet-hunting instrument SPHERE on the VLT has caught sight of the exoplanet Beta Pictoris b emerging from the bright halo of its parent star, 64 ligh...
