First Order Topological Phase Transitions and Disorder Induced Majorana Modes in Interacting Fermion Chains
Shruti Agarwal, Shreekant Gawande, Satoshi Nishimoto +2
Using a combination of the mean-field Bogoliubov deGennes (BdG) approach and the Density Matrix Renormalization Group (DMRG) method, we discover first order topological transitions…
Engineering antiferromagnetic skyrmions and antiskyrmions at metallic interfaces
Arnob Mukherjee, Deepak S. Kathyat, Sanjeev Kumar
We identify a mechanism to convert skyrmions and antiskyrmions into their antiferromagnetic (AFM) counterparts via interfacial engineering. The key idea is to combine properties of…
Spin- impurities with XXZ anisotropy in a spin-1/2 Heisenberg chain
Ayushi Singhania, Masahiro Kadosawa, Yukinori Ohta +2
We study the effect of anisotropy of spin- impurities on an antiferromagnetic SU(2) Heisenberg chain. The magnetic impurities are assumed to have an XXZ-type anisotropic exchang…
Complexity analysis of quantum teleportation via different entangled channels in the presence of noise
Deepak Singh, Sanjeev Kumar, Bikash K. Behera
Quantum communication is one of the hot topics in quantum computing, where teleportation of a quantum state has a slight edge and gained significant attention from researchers. A l…
Counterdiabatic route for preparation of state with long-range topological order
Sanjeev Kumar, Shekhar Sharma, Vikram Tripathi
We propose here a counterdiabatic (CD) strategy for fast preparation of a state with long-range topological order by magnetic field tuning of an initial separable state. For concre…
Pairing symmetries in the Zeeman-coupled extended attractive Hubbard model
Swagatam Nayak, Navketan Batra, Sanjeev Kumar
By introducing the possibility of equal- and opposite-spin pairings concurrently, we show that the extended attractive Hubbard model (EAHM) exhibits rich ground state phase diagram…
