Highly tunable magnetic phases in transition metal dichalcogenide Fe$_{1/3+δ}$NbS$_2$

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Shan Wu, Zhijun Xu, Shannon C. Haley, Sophie F. Weber, Arany Acharya | Summary: Layered transition metal dichalcogenides (TMDCs) host a plethora of interesting physical phenomena ranging from charge order to superconductivity. By introducing magnetic ions into 2H-NbS$_2$, the material forms a family of magnetic intercalated […]

Thermal anyon interferometry in phonon-coupled Kitaev spin liquids

Kavli Affiliate: Joel E. Moore | First 5 Authors: Kai Klocke, Joel E. Moore, Jason Alicea, Gábor B. Halász, | Summary: Recent theoretical studies inspired by experiments on the Kitaev magnet $alpha$-RuCl$_3$ highlight the nontrivial impact of phonons on the thermal Hall conductivity of chiral topological phases. Here we introduce mixed mesoscopic-macroscopic devices that allow […]

Vibronic coupling in energy transfer dynamics and two-dimensional electronic-vibrational spectra

Kavli Affiliate: Graham R. Fleming | First 5 Authors: Eric A. Arsenault, Addison J. Schile, David T. Limmer, Graham R. Fleming, | Summary: We introduce a heterodimer model in which multiple mechanisms of vibronic coupling and their impact on energy transfer can be explicitly studied. We consider vibronic coupling that arises through either Franck-Condon activity […]

Reinforcement learning of rare diffusive dynamics

Kavli Affiliate: David T. Limmer | First 5 Authors: Avishek Das, Dominic C. Rose, Juan P. Garrahan, David T. Limmer, | Summary: We present a method to probe rare molecular dynamics trajectories directly using reinforcement learning. We consider trajectories that are conditioned to transition between regions of configuration space in finite time, like those relevant […]

Continuous measurement of a qudit using dispersively coupled radiation

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: John Steinmetz, Debmalya Das, Irfan Siddiqi, Andrew N. Jordan, | Summary: We analyze the continuous monitoring of a qudit coupled to a cavity using both phase-preserving and phase-sensitive amplification. The quantum trajectories of the system are described by a stochastic master equation, for which we derive the […]

Spatiotemporal Crossover between Low- and High-Temperature Dynamical Regimes in the Quantum Heisenberg Magnet

Kavli Affiliate: Joel E. Moore | First 5 Authors: Maxime Dupont, Nicholas E. Sherman, Joel E. Moore, , | Summary: The stranglehold of low temperatures on fascinating quantum phenomena in one-dimensional quantum magnets has been challenged recently by the discovery of anomalous spin transport at high temperatures. Whereas both regimes have been investigated separately, no […]

Distinct chemistries explain decoupling of slip and wettability in atomically smooth aqueous interfaces

Kavli Affiliate: David T. Limmer | First 5 Authors: Anthony R. Poggioli, David T. Limmer, , , | Summary: Despite essentially identical crystallography and equilibrium structuring of water, nanoscopic channels composed of hexagonal boron nitride and graphite exhibit an order-of-magnitude difference in fluid slip. We investigate this difference using molecular dynamics simulations, demonstrating that its […]
