Emergent Potts Order in a Coupled Hexatic-Nematic XY model

1 code implementation2 Mar 2021 Victor Drouin-Touchette, Peter P. Orth, Piers Coleman, Premala Chandra, Tom C. Lubensky

Addressing the nature of an unexpected smectic-A' phase in liquid crystal 54COOBC films, we perform large scale Monte Carlo simulations of a coupled hexatic-nematic XY model.

Adaptive Variational Quantum Imaginary Time Evolution Approach for Ground State Preparation

1 code implementation2 Feb 2021 Niladri Gomes, Anirban Mukherjee, Feng Zhang, Thomas Iadecola, Cai-Zhuang Wang, Kai-Ming Ho, Peter P. Orth, Yong-Xin Yao

This ensures the state is able to follow the quantum imaginary time evolution path in the system Hilbert space rather than in a restricted variational manifold set by a predefined fixed ansatz.

Gutzwiller Hybrid Quantum-Classical Computing Approach for Correlated Materials

1 code implementation9 Mar 2020 Yongxin Yao, Feng Zhang, Cai-Zhuang Wang, Kai-Ming Ho, Peter P. Orth

Rapid progress in noisy intermediate-scale quantum (NISQ) computing technology has led to the development of novel resource-efficient hybrid quantum-classical algorithms, such as the variational quantum eigensolver (VQE), that can address open challenges in quantum chemistry, physics and material science.

Quantum Logic Gate Synthesis as a Markov Decision Process

no code implementations27 Dec 2019 M. Sohaib Alam, Noah F. Berthusen, Peter P. Orth

In the presence of gate noise, we demonstrate how the optimal policy adapts to the effects of noisy gates in order to achieve a higher state fidelity.

Extremely large magnetoresistance and Kohler's rule in PdSn4: a complete study of thermodynamic, transport and band structure properties

no code implementations18 Jul 2017 Na Hyun Jo, Yun Wu, Lin-Lin Wang, Peter P. Orth, Savannah S. Downing, Soham Manni, Dixiang Mou, Duane D. Johnson, Adam Kaminski, Sergey L. Bud'ko, Paul C. Canfield

By comparing these similar compounds, we address the origin of the extremely large magnetoresistance in PdSn$_4$ and PtSn$_4$; based on detailed analysis of the magnetoresistivity, $\rho(H, T)$, we conclude that neither carrier compensation nor the Dirac arc node surface state are primary reason for the extremely large magnetoresistance.
