Nitin Kaushal – Quantum Matter Institute Title: Realization of magnetically frustrated Wigner crystals and a novel multiorbital model in transition metal dichalcogenide based moiré materials Abstract: Moiré materials constructed using the transition metal dichalcogenide (TMD) bilayers have been used to simulate the Hubbard model with long range Coulomb interactions procuring the lattice Wigner crystal states […]

Andrea Young – University of California Santa Barbara Title: Magnetism and superconductivity in rhombohedral graphene multilayers: triplet superconductivity, intervalley coherence, and spin orbit coupling  Abstract: The electronic band structure of rhombohedral graphene multilayers hosts van Hove singularities at which the single particle of states diverges.  I will discuss experiments in which we use electrostatic gates […]

Kaoru Yamanouchi – Institute for Attosecond Laser Facility and Department of Chemistry, University of Tokyo Title: Quantum computing of atomic and molecular problems Abstract: Two-dimensional analogs of metal-halide perovskites represent a promising platform for exciton-polariton-based technologies. They sustain strongly bound excitons that are stable at room temperature, readily enabling strong light-matter coupling at ambient conditions. In the […]

CM Seminar: Carlos Silva-Acuña – Institut Courtois & Département de physique, Université de Montréal Title: Many-Body Exciton Polariton Quantum Dynamics in Optical Microcavities based on two-dimensional Metal-Halide Semiconductors Abstract: Two-dimensional analogs of metal-halide perovskites represent a promising platform for exciton-polariton-based technologies. They sustain strongly bound excitons that are stable at room temperature, readily enabling strong light-matter coupling at […]

Hao Tjeng – Max Planck Title: Stabilization of U 5f2 configuration in UTe2 through U 6d dimers in the presence of Te2 chains Abstract: We investigate the topological superconductor candidate UTe2 using high-resolution valence-band resonant inelastic x-ray scattering at the U M4,5-edges. We observe atomic-like low-energy excitations that support the correlated nature of this unconventional […]

CM Seminar: James McIver– Columbia University Title: Ultrafast optoelectronic circuits Abstract: Ultrafast optoelectronic circuits offer new opportunities for investigating and controlling the electrical responses of microstructured quantum materials and heterostructures at femtosecond timescales and THz frequencies. Based on metal waveguides and laser-triggered photoconductive switches, these chip-scale circuits can be interfaced to quantum materials to directly […]

CM Seminar: James Analytis – UC Berkley Title: Frustrated Quantum Devices: understanding how correlations, complex order and boundary states manifest in novel material functionalities Abstract: Materials at the boundary of critical phase transitions are of significant fundamental interest, not least due because of their connection to unconventional superconductivity and quantum magnetism. One characteristic of such […]

CM Seminar: Ania Bleszynski Jayich – University of California Santa Barbara Title: Quantum sensing in the solid-state: from one spin to many spins Abstract: Sensors that leverage quantum phenomena to measure physical quantities harbor many attractive features beyond classical sensors. Solid-state quantum sensors, with the nitrogen-vacancy (NV) center in diamond a forefront technology, are particularly attractive […]

Kamran Kamiri – National Centre for Nuclear Research, Poland Title: Multiscale Modeling of Mechanical Deformation in Chemically Complex Alloys Abstract: In my presentation, I will give an overview of three primary areas that have been my focal research interests at NOMATEN CoE: i) crystal and amorphous plasticity, ii) transport properties of high-entropy alloys (HEAs), and iii) […]
