Daniele Fausti: Cavity-Mediated Thermal Modulation ‌of the Metal-to-Insulator Transition in 1T-TaS2

This seminar will focus on the potential of cavity electrodynamics in shaping material properties, opened by on our recent investigation into cavity-mediated thermal control of the metal-to-insulator transition in 1T-TaS2, which demonstrated the feasibility of reversible cavity manipulation of a phase transition in a correlated solid-state material.By immersing the charge density wave material 1T-TaS2 into cryogenic tunable terahertz cavities, we unveil a remarkable shift between conductive s...

Martin Eckstein: Light-matter hybrids made from strongly correlated electron systems

Enhancing the light-matter coupling in cavities provides an intriguing avenue to control properties of matter, from chemical reactions to transport and thermodynamic phase transitions. In this talk, I discuss two mechanisms in which quantum light can influence extended condensed matter systems, in particular strongly correlated electron systems: (i) The hybridization of light and matter can affect first-order metal insulator transitions, because light selectively modifies the free energy of t...

Federico Cilento: Ultrafast Dynamics of the Charge Density Wave in Kagome Metals

The Charge Density Wave (CDW) order, descending from a metallic parent state, offers an intriguing playground to study the interplay of structural and electronic degrees of freedom in complex materials. Recently, this phenomenology has been discovered also in Kagome metals. With dispersive and correlation features including topological Dirac-like itinerant states, van-Hove singularities, correlated flat bands, and magnetic transitions at low temperature, kagome metals are located in the inter...

Michael Sentef: Light-Matter Control of Quantum Materials

Advances in time-resolved pump-probe spectroscopies have enabled us to follow the microscopic dynamics of quantum materials on femtosecond time scales. This gives us a glimpse into the inner workings of how complex, emergent functionalities of quantum many-body systems develop on ultrafast time scales or react to external forces. The ultimate dream of the community is to use light as a tuning parameter to create new states of matter on demand with designed properties and new functionalities, ...

James McIver: Ultrafast control of topological transport in quantum materials

Quantum materials exhibit remarkable non-equilibrium phenomena when driven by the strong fields in femtosecond laser pulses. Recent years have seen a surge of interest in using ultrafast light-matter interaction to create and manipulate photon-dressed Floquet-Bloch states as a strategy for controlling material properties. This excitement is fueled by the predictive power of Floquet theory, which has been used, for example, to correctly predict the formation of topological edge modes in period...

Sourav Nandy: Emergent dipole moment conservation and subdiffusion in tilted chains

I plan to talk regarding the transport dynamics of an interacting tilted (Stark) chain, based on our recent work. In this work, we have shown that the crossover between diffusive and subdiffusive dynamics in such a system is governed by F√L, where F is the strength of the field, and L is the wave-length of the excitation. While the subdiffusive dynamics persist for large fields, the corresponding transport coefficient is exponentially suppressed with F so that the finite-time dynamics appea...

Andrei Kirilyuk: Shaken, not stirred: a recipe for ultrafast magnetic switching ‌via phononic resonances

Strong light-matter interaction constitutes the bedrock of all photonic applications, empowering material elements to create and mediate interactions of light with light. Among others, phononamplified interactions were shown to bring a specific twist into this, in the infrared (IR) frequency range. Thus, phono-magnetic effects are the low-frequency analogues of inverse Faraday and Cotton-Mouton effects where phonons, not electrons, mediate the interaction between light and spins. In this case...

Philipp Werner: Photo-induced nonthermal metals

Several insulating materials can be switched by laser pulses into transient metal states with apparently nonthermal properties. Often, this has been interpreted as a nonthermal closing of a Mott gap. An alternative mechanism is the generation of in-gap states by the nonthermal population of multiplets (e. g. singlet-triplet excitations in dimerized systems), or the nonthermal reshuffling of charge between orbitals. I will present recent nonequilibrium dynamical mean field theory studies of mo...

Kazuki Yamamoto: Entanglement phase transition under continuously monitored dynamics ‌in many-body localized systems

Localization, which is typically induced by disorder, is an exotic phenomenon where a quantum state fails to spread over the entire Hilbert space. Recently, measurement is utilized as another mechanism to localize a quantum state in nonunitary quantum circuits and continuously monitored systems, which exhibit novel quantum phenomena dubbed measurement-induced phase transitions (MIPTs). However, while both the disorder and the measurement localize the wave function and suppress the entanglemen...

Giuliano Chiriaco: Entanglement transition and monogamy effects in non-Markovian systems

In the last few years there has been great interest in the dynamics of monitored quantum many-body systems. The interplay between unitary evolution and dissipative dynamics leads to many effects, including measurement induced phase transitions of the entanglement scaling. While earlier works all considered Markovian dissipative processes, lately there has been growing interest in non-Markovian dissipation and the effect of memory on entanglement transitions.I will present recent results and d...

Jaka Vodeb: Probing Dynamical Resonances In A 5564 Qubit Quantum Annealer

Understanding the dynamics of complex, strongly interacting many-body systems is crucial in the field of quantum science and engineering. Recent advancements in controlling programmable many-body systems have provided insights into nonequilibrium states, often inaccessible to classical simulations. This talk explores the concept of dynamical resonances, which are radically distinct magnetization dynamics occurring only within a very narrow parameter regime, in the transverse field Ising model...

Jernej Mravlje: Ta2NiSe5: excitonic or not?

Ta2NiSe5 has long been considered as a prominent candidate for realization of the excitonic condensation that was invoked to explain the opening of the gap in the photoemission and to rationalize the existence of short time scales in pump-probe experiments. A structural transition that coincides with the putative excitonic transition leads to eternal chicken-egg debate addressing the dominant mechanism of the transition. We consider a realistic 6 orbital model and discuss its instabilities i...

Alexander Osterkorn: Current-induced excitonic condensation in bilayer systems

Excitons are correlated electron-hole pairs in multi-band electron systems, which can condense and form ordered phases of matter called excitonic insulators. These are expected to display novel and technologically highly relevant features like superfluid energy transport. While it is experimentally challenging to identify real materials hosting equilibrium excitonic order, out-of-equilibrium protocols open up an independent route to stabilize excitonic condensates.Ma proposed a gated s...
