Metal-Insulator Transition and Emergent Gapped Phase in the Surface-Doped 2D Semiconductor 2H-MoTe2

期刊: PHYSICAL REVIEW LETTERS, 2021; 126 (10)

Artificially created two-dimensional (2D) interfaces or structures are ideal for seeking exotic phase transitions due to their highly tunable carrier ......

Total Angular Momentum Dichroism of the Terahertz Vortex Beams at the Anti ferromagnetic Resonances

期刊: PHYSICAL REVIEW LETTERS, 2021; 126 (15)

Terahertz vortex beams with different superposition of the orbital angular momentum l = +/- 1, +/- 2, +/- 3, and +/- 4 and spin angular momentum sigma......

Droplets Sit and Slide Anisotropically on Soft, Stretched Substrates

期刊: PHYSICAL REVIEW LETTERS, 2021; 126 (15)

Anisotropically wetting substrates enable useful control of droplet behavior across a range of applications. Usually, these involve chemically or phys......

Confusing Head-On Collisions with Precessing Intermediate-Mass Binary Black Hole Mergers

期刊: PHYSICAL REVIEW LETTERS, 2021; 126 (20)

We report a degeneracy between the gravitational-wave signals from quasicircular precessing black-hole mergers and those from extremely eccentric merg......

Observation of Negative Terahertz Photoconductivity in Large Area Type-II Dirac Semimetal PtTe2

期刊: PHYSICAL REVIEW LETTERS, 2021; 126 (22)

As a newly emergent type-II Dirac semimetal, platinum telluride (PtTe2) stands out from other two dimensional noble-transition-metal dichalcogenides f......

Pairing Forces Govern Population of Doubly Magic Ca-54 from Direct Reactions

期刊: PHYSICAL REVIEW LETTERS, 2021; 126 (25)

Direct proton-knockout reactions of Sc-55 at similar to 220 MeV/nucleon were studied at the RIKEN Radioactive Isotope Beam Factory. Populated states o......

Probing Rotated Weyl Physics on Nonlinear Lithium Niobate-on-Insulator Chips

期刊: PHYSICAL REVIEW LETTERS, 2021; 127 (1)

Topological photonics, featured by stable topological edge states resistant to perturbations, has been utilized to design robust integrated devices. H......

Direct Measurement of Topological Properties of an Exceptional Parabola

期刊: PHYSICAL REVIEW LETTERS, 2021; 127 (3)

Non-Hermitian systems can produce branch singularities known as exceptional points (EPs). Different from singularities in Hermitian systems, the topol......

Dark Matter Freeze-Out via Catalyzed Annihilation

期刊: PHYSICAL REVIEW LETTERS, 2021; 127 (6)

We present a new paradigm of dark matter freeze-out, where the annihilation of dark matter particles is catalyzed. We discuss in detail the regime in ......

Parity-Symmetry-Protected Multiphoton Bundle Emission

期刊: PHYSICAL REVIEW LETTERS, 2021; 127 (7)

We demonstrate symmetry protected multiphoton bundle emission in the cavity QED system under the ultrastrong coupling regime. Our proposal only enable......

Anapole Meta-Atoms: Nonradiating Electric and Magnetic Sources

期刊: PHYSICAL REVIEW LETTERS, 2021; 127 (9)

The existence of classical nonradiating electromagnetic sources is one of the puzzling questions to date. Here, we investigate radiation properties of......

Unraveling the Orbital Physics in a Canonical Orbital System KCuF3

期刊: PHYSICAL REVIEW LETTERS, 2021; 126 (10)

We explore the existence of the collective orbital excitations, orbitons, in the canonical orbital system KCuF3 using the Cu L-3-edge resonant inelast......

Synthetic Gauge Fields in a Single Optomechanical Resonator

期刊: PHYSICAL REVIEW LETTERS, 2021; 126 (12)

Synthetic gauge fields have recently emerged, arising in the context of quantum simulations, topological matter, and the protected transportation of e......

Experimental Demonstration of a Multifunctional All-Optical Quantum State Transfer Machine

期刊: PHYSICAL REVIEW LETTERS, 2021; 126 (21)

Quantum information protocol with quantum resources shows a great advantage in substantially improving security, fidelity, and capacity of information......

Single-Atom Verification of the Noise-Resilient and Fast Characteristics of Universal Nonadiabatic Noncyclic Geometric Quantum Gates

期刊: PHYSICAL REVIEW LETTERS, 2021; 127 (3)

Quantum gates induced by geometric phases are intrinsically robust against noise due to the global properties of their evolution paths. Compared to co......
