Orbital Frontiers: Harnessing Higher Modes in Photonic Simulators
Jiho Noh, Julian Schulz, Wladimir Benalcazar +1
Photonic platforms have emerged as versatile and powerful classical simulators of quantum dynamics, providing clean, controllable optical analogs of extended structured (i.e., crys…
Giant non-reciprocity and gyration through modulation-induced Hatano-Nelson coupling in integrated photonics
Ogulcan E. Orsel, Jiho Noh, Penghao Zhu +4
Asymmetric energy exchange interactions, also known as Hatano-Nelson type couplings, enable the study of non-Hermitian physics and associated phenomena like the non-Hermitian skin…
A mono-atomic orbital-based 1D topological crystalline insulator
Gengming Liu, Violet Workman, Jiho Noh +4
Topological crystalline insulators (TCIs) are classified by topological invariants defined with respect to the crystalline symmetries of their gapped bulk. The bulk-boundary corres…
Electrically-Controlled Suppression of Rayleigh Backscattering in an Integrated Photonic Circuit
Ogulcan E. Orsel, Jiho Noh, Gaurav Bahl
Undesirable light scattering is an important fundamental cause for photon loss in nanophotonics. Rayleigh backscattering can be particularly difficult to avoid in wave-guiding syst…
Scattering theory of delicate topological insulators
Penghao Zhu, Jiho Noh, Yingkai Liu +1
We study the scattering theory of delicate topological insulators (TIs), which are novel topological phases beyond the paradigm of the tenfold way, topological quantum chemistry, a…
Photonic quadrupole topological insulator using orbital-induced synthetic flux
Julian Schulz, Jiho Noh, Wladimir A. Benalcazar +2
The rich physical properties of multiatomic molecules and crystalline structures are determined, to a significant extent, by the underlying geometry and connectivity of atomic orbi…
Spontaneously-Induced Dirac Boundary State and Digitization in a Nonlinear Resonator Chain
Gengming Liu, Jiho Noh, Jianing Zhao +1
The low-energy excitations in many condensed matter and metamaterial systems can be well described by the Dirac equation. The mass term associated with these collective excitations…
Observation of Quadratic (Charge-2) Weyl Point Splitting in Near-Infrared Photonic Crystals
Christina Jörg, Sachin Vaidya, Jiho Noh +4
Weyl points are point degeneracies that occur in momentum space of periodic materials, and are associated with a quantized topological charge. We experimentally observe in a 3D mic…
Higher-order topological pumping and its observation in photonic lattices
Wladimir A. Benalcazar, Jiho Noh, Mohan Wang +3
The discovery of the quantization of particle transport in adiabatic pumping cycles of periodic structures by Thouless [Phys. Rev. B 27, 6083 (1983)] linked the Chern number, a top…
Observation of a charge-2 photonic Weyl point in the infrared
Sachin Vaidya, Jiho Noh, Alexander Cerjan +1
Weyl points are robust point degeneracies in the band structure of a periodic material, which act as monopoles of Berry curvature. They have been at the forefront of research in th…
Braiding photonic topological zero modes
Jiho Noh, Thomas Schuster, Thomas Iadecola +5
A remarkable property of quantum mechanics in two-dimensional (2D) space is its ability to support "anyons," particles that are neither fermions nor bosons. Theory predicts that th…
Observation of Photonic Topological Valley-Hall Edge States
Jiho Noh, Sheng Huang, Kevin Chen +1
We experimentally demonstrate topological edge states arising from the valley-Hall effect in twodimensional honeycomb photonic lattices with broken inversion symmetry. We break inv…
Topological protection of photonic mid-gap cavity modes
Jiho Noh, Wladimir A. Benalcazar, Sheng Huang +4
Defect modes in two-dimensional periodic photonic structures have found use in a highly diverse set of optical devices. For example, photonic crystal cavities confine optical modes…
Experimental observation of optical Weyl points
Jiho Noh, Sheng Huang, Daniel Leykam +3
Weyl fermions are hypothetical two-component massless relativistic particles in three-dimensional (3D) space, proposed by Hermann Weyl in 1929. Their band-crossing points, called '…
Core-Shell Magneto-Optical Trap for Alkaline-Earth-Metal-Like Atoms
Jeongwon Lee, Jae Hoon Lee, Jiho Noh +1
We propose and demonstrate a new magneto-optical trap (MOT) for alkaline-earth-metal-like (AEML) atoms where the narrow transition and the broad $…
Observation of the universal jump across the Berezinskii-Kosterlitz-Thouless transition in two-dimensional Bose gases
Jiho Noh, Jeongwon Lee, Jongchul Mun
The physics in two-dimensional (2D) systems is very different from what we observe in three-dimensional (3D) systems. Thermal fluctuations in 2D systems are enhanced, and they prev…
