Imaging gate-tunable Tomonaga-Luttinger liquids in 1H-MoSe$_2$ mirror twin boundaries

Posted by Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Tiancong Zhu, Wei Ruan, Yan-Qi Wang, Hsin-Zon Tsai, Shuopei Wang | Summary: One-dimensional electron systems (1DESs) exhibit properties that are fundamentally different from higher-dimensional systems. For example, electron-electron interactions in 1DESs have been predicted to induce Tomonaga-Luttinger liquid behavior. Naturally-occurring grain boundaries in single-layer semiconducting transition […]

A quantum hamiltonian simulation benchmark

Posted by klaurent Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Yulong Dong, K. Birgitta Whaley, Lin Lin, , | Summary: Hamiltonian simulation is one of the most important problems in quantum computation, and quantum singular value transformation (QSVT) is an efficient way to simulate a general class of Hamiltonians. However, the QSVT circuit typically involves multiple ancilla […]

Forecasting racial dynamics at the neighborhood scale using Density-functional Fluctuation Theory

Posted by klaurent Cornell

Kavli Affiliate: Itai Cohen | First 5 Authors: Yunus A. Kinkhabwala, Boris Barron, Matthew Hall, Tomas A. Arias, Itai Cohen | Summary: Racial residential segregation is a defining and enduring feature of U.S. society, shaping inter-group relations, racial disparities in income and health, and access to high-quality public goods and services. The design of policies […]

Fast universal quantum control above the fault-tolerance threshold in silicon

Posted by klaurent Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Akito Noiri, Kenta Takeda, Takashi Nakajima, Takashi Kobayashi, Amir Sammak | Summary: Fault-tolerant quantum computers which can solve hard problems rely on quantum error correction. One of the most promising error correction codes is the surface code, which requires universal gate fidelities exceeding the error correction threshold […]

Measuring photoexcited electron and hole dynamics in ZnTe and modeling excited state core-valence effects in transient XUV reflection spectroscopy

Posted by klaurent Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Hanzhe Liu, Jonathan M. Michelsen, Isabel M. Klein, Scott K. Cushing, | Summary: Transient XUV spectroscopy is growing in popularity for the measurement of solar fuel and photovoltaic materials as it can separately measure electron and hole energies for multiple elements at once. However, interpretation of […]

Topological Optical Parametric Oscillation

Posted by klaurent Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Arkadev Roy, Midya Parto, Rajveer Nehra, Christian Leefmans, Alireza Marandi | Summary: Topological insulators possess protected boundary states which are robust against disorders and have immense implications in both fermionic and bosonic systems. Harnessing these topological effects in non-equilibrium scenarios is highly desirable and has led to […]

Circuit quantum electrodynamics with two remote electron spins

Posted by klaurent Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Patrick Harvey-Collard, Jurgen Dijkema, Guoji Zheng, Amir Sammak, Giordano Scappucci | Summary: We report the coherent coupling of two electron spins at a distance via virtual microwave photons. Each spin is trapped in a silicon double quantum dot at either end of a superconducting resonator, achieving spin-photon […]

Directional excitation of a high-density magnon gas using coherently driven spin waves

Posted by klaurent Delft

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Brecht G. Simon, Samer Kurdi, Helena La, Iacopo Bertelli, Joris J. Carmiggelt | Summary: Controlling magnon densities in magnetic materials enables driving spin transport in magnonic devices. We demonstrate the creation of large, out-of-equilibrium magnon densities in a thin-film magnetic insulator via microwave excitation of […]
