Magneto-optical study of metamagnetic transitions in the antiferromagnetic phase of alpha-RuCl3

alpha-RuCl3 is a promising candidate material to realize the so far elusive quantum spin liquid ground state. However, at low temperatures, the coexistence of different exchange interactions couple the effective pseudospins into an antiferromagnetically zi ...

Polaritonic Cross Feshbach Resonance

Daniel Oberli, Marcia Portella Oberli, Mitchell David Anderson, Naotomo Takemura, Morteza Navadeh Toupchi

We demonstrate the existence of a cross Feshbach resonance by strongly driving a lower polariton mode and by monitoring in time the transmission of a short optical pulse at the energy of the upper polariton mode in a semiconductor microcavity. From the sig ...

Near optimal graphene terahertz non-reciprocal isolator

Juan Ramon Mosig, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Julien Perruisseau-Carrier, Michele Tamagnone

Isolators, or optical diodes, are devices enabling unidirectional light propagation by using non-reciprocal optical materials, namely materials able to break Lorentz reciprocity. The realization of isolators at terahertz frequencies is a very important ope ...

Anomalously thick domain walls in ferroelectrics

Nava Setter, Alexander Tagantsev, Tomas Sluka, Maxim Gureev, Petr Yudin

Using the Landau theory we demonstrate the possibility of unusual, anomalously thick ferroelectric domain walls, where the order parameter rotates with a nearly constant modulus as in ferromagnets. The effect occurs in 90 degrees charged domain walls and i ...

Internal optical forces in plasmonic nanostructures

Olivier Martin, Raziman Thottungal Valapu

We present a computational study of the internal optical forces arising in plasmonic gap antennas, dolmen structures and split rings. We find that very strong internal forces perpendicular to the propagation direction appear in these systems. These interna ...

Coupling Strength Can Control the Polarization Twist of a Plasmonic Antenna

Olivier Martin, Christian Santschi, Shourya Dutta Gupta, Banafsheh Abasahl

The far-field polarization of the optical response of a plasmonic antenna can be tuned by subtly engineering of its geometry. In this paper, we develop design rules for nano antennas which enable the generation of circular polarized light via the excitatio ...
