Probing the Material Loss and Optical Nonlinearity of Integrated Photonic Materials

Tobias Kippenberg, Junqiu Liu, Guanhao Huang

Optical absorption and nonlinear index are important performance drivers in devices like microcombs and parametric oscillators. Here we use resonance-enhanced nonlinear spectroscopy to characterize absorption limits and nonlinear index for some integrated ...

Coupled VO2 oscillators circuit as analog first layer filter in convolutional neural networks

Mihai Adrian Ionescu, Kirsten Emilie Moselund, Elisabetta Corti, Siegfried Karg

In this work we present an in-memory computing platform based on coupled VO2 oscillators fabricated in a crossbar configuration on silicon. Compared to existing platforms, the crossbar configuration promises significant improvements in terms of area densit ...

Atom-surface van der Waals potentials of topological insulators and semimetals from scattering measurements

Davide Campi

The phenomenology of resonant scattering has been known since the earliest experiments upon scattering of atomic beams from surfaces and is a means of obtaining experimental information about the fundamentals of weak adsorption systems in the van der Waals ...

Magnetic-Field-Induced Bound States in Spin-1/2 Ladders

Frédéric Mila, Mithilesh Nayak

Motivated by the recently observed intriguing mode splittings in a magnetic field with inelastic neutron scattering in the spin ladder compound (C5H12N)(2) CuBr4 (BPCB), we investigate the nature of the spin ladder excitations using a density matrix renorm ...

Vibrationally inelastic scattering of HCl from Ag(111)

Jan Daniel Geweke

Using molecular beam cooled samples and quantum state-selective detection, we observe v = 0 -> 1 vibrational transitions when HCl (v = 0) collides with an Ag(111) surface and derive both the incidence energy and surface temperature dependence of the transi ...

Multiphase magnetism in Yb2Ti2O7

Gregory Scott Tucker

We use neutron scattering to show that ferromagnetism and antiferromagnetism coexist in the low T state of the pyrochlore quantum magnet Yb2Ti2O7. While magnetic Bragg peaks evidence long-range static ferromagnetic order, inelastic scattering shows that sh ...

Dissipative-coupling-assisted laser cooling: Limitations and perspectives

Alexander Tagantsev

The recently identified possibility of ground-state cooling of a mechanical oscillator in the unresolved sideband regime by combination of the dissipative and dispersive optomechanical coupling under the red sideband excitation [Phys. Rev. A 88, 023850 (20 ...

Unraveling intrinsic correlation effects with angle-resolved photoemission spectroscopy

Marco Vanzini, Vladimir N. Strocov

Interaction effects can change materials properties in intriguing ways, and they have, in general, a huge impact on electronic spectra. In particular, satellites in photoemission spectra are pure many-body effects, and their study is of increasing interest ...

State-to-state methane-surface scattering as a probe of catalytic activity

Rainer Beck, Maarten Eduard van Reijzen, Jörn Werdecker, Bo-Jung Chen

Quantum state-resolved scattering experiments for methane molecules colliding with a catalytically active nickel surface are compared to scattering from a nickel surface passivated by a single layer of graphene. The vibrational state distribution of the sc ...
