Full tunability enabled by Floquet engineering in a multilevel quantum dot system

Kavli Affiliate: Ke Wang | First 5 Authors: Yuan Zhou, Sisi Gu, Ke Wang, Gang Cao, Xuedong Hu | Summary: Tunability of an artificial quantum system is crucial to its capability to process quantum information. However, tunability usually poses significant demand on the design and fabrication of a device. In this work, we demonstrate that […]

The Simons Observatory: Constraining inflationary gravitational waves with multi-tracer B-mode delensing

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Anton Baleato Lizancos, Naomi Robertson, Blake D. Sherwin, Anthony Challinor | Summary: We introduce and validate a delensing framework for the Simons Observatory (SO), which will be used to improve constraints on inflationary gravitational waves (IGWs) by reducing the lensing noise in measurements of the […]

Valley transport driven by dynamic lattice distortion

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Yuya Ominato, Daigo Oue, Mamoru Matsuo, , | Summary: Angular momentum conversion between mechanical rotation and the valley degree of freedom in 2D Dirac materials is investigated theoretically. Coupling between the valley and vorticity of dynamic lattice distortions is derived by applying the k.p method to 2D […]

TESS Hunt for Young and Maturing Exoplanets (THYME) VI: an 11 Myr giant planet transiting a very low-mass star in Lower Centaurus Crux

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Andrew W. Mann, Mackenna L. Wood, Stephen P. Schmidt, Madyson G. Barber, James E. Owen | Summary: Mature super-Earths and sub-Neptunes are predicted to be $simeq$Jovian radius when younger than 10 Myr. Thus, we expect to find 5-15$R_oplus$ planets around young stars even if their older counterparts […]

Establishing the Non-Primordial Origin of Black Hole-Neutron Star Mergers

Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Volodymyr Takhistov, Valeri Vardanyan, Ying-li Zhang, | Summary: Primordial black holes (PBHs) from the early Universe constitute an attractive dark matter candidate. First detections of black hole-neutron star (BH-NS) candidate gravitational wave events by the LIGO/Virgo collaboration, GW200105 and GW200115, already prompted speculations about non-astrophysical […]

Interplay of vibration- and environment-assisted energy transfer

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Zeng-Zhao Li, Liwen Ko, Zhibo Yang, Mohan Sarovar, K. Birgitta Whaley | Summary: We study the interplay between two environmental influences on excited state energy transfer in photosynthetic light harvesting complexes, namely, vibrationally assisted energy transfer(VAET) and environment-assisted quantum transport (ENAQT), considering a dimeric chromophore donor-acceptor […]

Universal finite-size amplitude and anomalous entanglement entropy of $z=2$ quantum Lifshitz criticalities in topological chains

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, T. A. Sedrakyan, , , | Summary: We consider Lifshitz criticalities with dynamical exponent $z=2$ that emerge in a class of topological chains. There, such a criticality plays a fundamental role in describing transitions between symmetry-enriched conformal field theories (CFTs). We report that, at such […]
