General Construction from Topological Loop States to Topological Invariants in Exactly Flat Bands
Rui-Heng Liu, Jiangping Hu, Chen Fang
Electronic flat bands have localized Wannier-like orbitals as zero modes. In the Lieb or the kagome models, the localized orbitals satisfy a topological condition that entails two…
Unconventional Electromechanical Response in Ferrocene Assisted Gold Atomic Chain
Biswajit Pabi, Štěpán Marek, Tal Klein +3
Atomically thin metallic chains serve as pivotal systems for studying quantum transport, with their conductance strongly linked to the orbital picture. Here, we report a non-monoto…
Quantum thermocouples: nonlocal conversion and control of heat in nanostructures
José Balduque, Rafael Sánchez
Nanoscale conductors are interesting for thermoelectrics because of their particular spectral features connecting separated heat and particle currents. Multiterminal devices in the…
Single-layer magnet phase in intrinsic magnetic topological insulators, , far beyond the thermodynamic limit
Deepti Jain, Hee Taek Yi, Xiong Yao +6
The intrinsic magnetic topological insulator (IMTI) family has demonstrated magneto-topological properties dependent…
Impact of charge transfer excitons on unidirectional exciton transport in lateral TMD heterostructures
Roberto Rosati, Sai Shradha, Julian Picker +3
Lateral heterostructures built of monolayers of transition metal dichalcogenides (TMDs) are characterized by a thin 1D interface exhibiting a large energy offset. Recently, the for…
Impact of the angular alignment on the crystal field and intrinsic doping of bilayer graphene/BN heterostructures
L. S. Farrar, G. Maffione, V. -H. Nguyen +5
The ability to tune the energy gap in bilayer graphene makes it the perfect playground for the study of the effects of internal electric fields, such as the crystalline field, whic…
Data needs and challenges for quantum dot devices automation
Justyna P. Zwolak, Jacob M. Taylor, Reed W. Andrews +17
Gate-defined quantum dots are a promising candidate system for realizing scalable, coupled qubit systems and serving as a fundamental building block for quantum computers. However,…
Voltage-controlled binary conductance switching in gold-4,4'-bipyridine-gold single-molecule nanowires
Gréta Mezei, Zoltán Balogh, András Magyarkuti +1
We investigate gold-4,4'-bipyridine-gold single-molecule junctions with the mechanically controllable break junction technique at cryogenic temperature (). We obse…
Hybridized intervalley moiré excitons and flat bands in twisted WSe bilayers
Samuel Brem, Kai-Qiang Lin, Roland Gillen +4
The large surface-to-volume ratio in atomically thin 2D materials allows to efficiently tune their properties through modifications of their environment. Artificial stacking of two…
KH2PO4 + Host Matrix (Alumina / SiO) Nanocomposite: Raman Scattering Insight
Ya. Shchur, A. S. Andrushchak, V. V. Strelchuk +6
We report on the synthesis and Raman scattering characterization of composite materials based on the hostnanoporous matrices filled with nanostructured KH2PO4 (KDP) crystal. Silica…
Anomalous zero-temperature magnetopolaronic blockade of resonant electron tunneling in Majorana-resonant-level single-electron transistor
G. A. Skorobagatko
The magnetopolaronic generalization of a Majorana-resonant-level (MRL) model is considered for a single-level vibrating quantum dot coupled to two half-infinite Tomonaga-Lu…
Noise suppression and long-range exchange coupling for gallium arsenide spin qubits
Filip Kazimierz Malinowski
This thesis presents the results of the experimental study performed on spin qubits realized in gate-defined gallium arsenide quantum dots, with the focus on noise suppression and…
Non-invasive transmission electron microscopy of vacancy defects in graphene produced by ion irradiation

Polarization resolved, Raman scattering response due to E phonon in monolayer graphene has been investigated in magnetic fields up to 29 T. The hybridization of the E…
How close can one approach the Dirac point in graphene experimentally?
Alexander S. Mayorov, Daniel C. Elias, Ivan S. Mukhin +5
The above question is frequently asked by theorists who are interested in graphene as a model system, especially in context of relativistic quantum physics. We offer an experimenta…
Atomically thin boron nitride: a tunnelling barrier for graphene devices
Liam Britnell, Roman V. Gorbachev, Rashid Jalil +12
We investigate the electronic properties of heterostructures based on ultrathin hexagonal boron nitride (h-BN) crystalline layers sandwiched between two layers of graphene as well…
On resonant scatterers as a factor limiting carrier mobility in graphene
Z. H. Ni, L. A. Ponomarenko, R. R. Nair +8
We show that graphene deposited on a substrate has a non-negligible density of atomic scale defects. This is evidenced by a previously unnoticed D peak in the Raman spectra with in…
Nonlinear relaxation of 0-dimension-trapped microcavity polaritons
Ounsi El Daif, Gael Nardin, Taofiq K. Paraiso +6
We study the emission properties of confined polariton states in shallow zero-dimensional traps under non-resonant excitation. We evidence several relaxation regimes. For slightly…
