Fluctuation Relations for Dissipative Systems in Constant External Magnetic Field: Theory and Molecular Dynamics Simulations

Sara Bonella, Alessandro Coretti

We illustrate how, contrary to common belief, transient Fluctuation Relations (FRs) for systems in constant external magnetic field hold without the inversion of the field. Building on previous work providing generalized time-reversal symmetries for syste ...

Fabrication and applications of AuAg alloy metasurfaces and hybrid metal dielectric nanoantennas

Debdatta Ray

The most prevalent materials used in the field of plasmonics are Au and Ag. However, for the past few years, the plasmonic community has also been looking for alternative materials that have lower losses than Au and higher stability than Ag. This thesis is ...

Spontaneous formation of ordered micro-wrinkles on a thermosensitive resist

Jürgen Brugger, Giovanni Boero, Xia Liu, Ana Conde Rubio, Mohammadreza Rostami

Self-organizing patterns with micrometer-scale features are promising for applications in photonics and bioengineering. Their spontaneous formation reduces the number of required processing steps. Here, we report an approach to spontaneously form stochasti ...

Fabrication of plasmonic structures with well-controlled nanometric features: a comparison between lift-off and ion beam etching

Olivier Martin, Christian Santschi, Banafsheh Abasahl

After providing a detailed overview of nanofabrication techniques for plasmonics, we discuss in detail two different approaches for the fabrication of metallic nanostructures based on e-beam lithography. The first approach relies on a negative e-beam resis ...

Strong photon coupling to the quadrupole moment of an electron in a solid-state qubit

Pasquale Scarlino

The fundamental concept of light–matter interaction is routinely realized by coupling the quantized electric field in a cavity to the dipole moment of a real or an artificial atom. A recent proposal1,2, motivated by the prospect of overcoming the decoherin ...

Diffractive optical elements in single crystal diamond

Niels Quack

We demonstrate the design, fabrication, and experimental characterization of near-field binary phase transmission diffractive optical elements (DOEs) in single crystal diamond. Top-hat and arbitrary pattern DOE beam shapers were numerically optimized using ...

Persistence of Magnetism in Atomically Thin MnPS3 Crystals

Dumitru Dumcenco, Marco Gibertini, Zhe Wang

The magnetic state of atomically thin semiconducting layered antiferromagnets such as CrI3 and CrCI3 can be probed by forming tunnel barriers and measuring their resistance as a function of magnetic field (H) and temperature (T). This is possible because t ...
