Resonant Perfect Absorption Yielded By Zero-Area Pulses, Yu He, Zuoye Liu, Christian Ott, Adrian N. Pfeiffer, Shaohua Sun, Mette B. Gaarde, Thomas Pfeifer, Bitao Hu

Faculty Publications

We propose and study the manipulation of the macroscopic transient absorption of an ensemble of open two-level systems via temporal engineering. The key idea is to impose an ultrashort temporal gate on the polarization decay of the system by transient absorption spectroscopy, thus confining its free evolution and the natural reshaping of the excitation pulse. The numerical and analytical results demonstrate that even at moderate optical depths, the resonant absorption of light can be reduced or significantly enhanced by more than 5 orders of magnitude relative to that without laser manipulation. The achievement of the quasicomplete extinction of light at …

Series of events show that Southeast Asian electoral democracies are receding back to full authoritarianism, and such a phenomenon requires academic attention to investigate its pattern. This paper explores the impact of Chinese patronage on Southeast Asian democracy and argues that its economic and normative support of autocrats enable the continuation of an authoritarian turn in Southeast Asia. Two cases of the Philippines and Cambodia unravel how Chinese patronage leads to autocrats’ disregard for liberal pressures. The logic is twofold. First, …

A Simulation Methodology For Superconducting Qubit Readout Fidelity, Hiu Yung Wong, Prabjot Dhillon, Kristin M. Beck, Yaniv J. Rosen

Faculty Research, Scholarly, and Creative Activity

Qubit readout is a critical part of any quantum computer including the superconducting-qubit-based one. The readout fidelity is affected by the readout pulse width, readout pulse energy, resonator design, qubit design, qubit-resonator coupling, and the noise generated along the readout path. It is thus important to model and predict the fidelity based on various design parameters along the readout path. In this work, a simulation methodology for superconducting qubit readout fidelity is proposed and implemented using Matlab and Ansys HFSS to allow co-optimization in the readout path. As an example, parameters are taken from an actual superconducting-qubit-based quantum computer. Without …

Domestic Terrorism Classification In The United States V. Canada And The United Kingdom, Michelle Hayek

Brooklyn Journal of International Law

For the past two decades, discourse on terrorism (both global and domestic) has been commonplace throughout the international sphere. Following the attacks on September 11, 2001, many nations have followed suit in launching counterterrorism operations to identify and prevent attacks by both radical groups and lone actors. While the common narrative has focused on “why” terrorist actors commit heinous acts and “how” to best prevent future incidents from emerging, it is important to analyze the legal nuances between prosecuting domestic versus international terrorists. With the rise on “homegrown” domestic lone actors, nations have had to reevaluate and adapt counterterrorism statutes …
