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 […]
